Principle of laser freckle removal
Skin spots include epidermal spots such as freckles, coffee spots and senile spots, as well as dermal spots such as chloasma and nevus OTA. The principle of laser freckle removal is that the laser instrument emits light with a specific wavelength, and these concentrated high energies will decompose pigments and excrete them with the normal metabolism of the human body, thus achieving the effect of freckle removal and whitening. Because the light with a specific wavelength can only be absorbed by the pigment, laser freckle will not harm the normal part of the skin, which is often called the "selective photothermal principle".
Advantages of laser freckle removal
Compared with drug therapy and skin care products conditioning, laser freckle removal can directly and effectively remove skin pigment and excrete it, and the effect is faster.
Laser freckle is a minimally invasive cosmetic surgery, and the wound is only for long spots. There was no bleeding during the operation, and the skin recovered quickly, leaving no trace.
In addition, laser freckle can not only remove facial blemishes, but also use its toner to treat head, improve skin quality and whiten skin.
Eight misunderstandings of laser freckle removal
1 Does the laser make the skin thinner?
Many people think that laser beauty will damage the skin, and the skin surface will be destroyed, just like the wall skin is chiseled off, and it will become thinner and thinner.
In fact, after the age of 25, with the growth of age, our skin is losing collagen and elastin, and the skin is gradually thinning. Laser can fade the color spots, remove the dilated small blood vessels, repair the skin damaged by light and improve the appearance of the skin through selective thermal action.
At the same time, the photothermal effect of laser can activate skin fibroblasts, increase the expression of collagen, change the molecular structure of dermal collagen fibers and elastic fibers, increase the number and rearrange them, and restore the elasticity of skin, thus reducing wrinkles and pores.
Therefore, laser beauty will not only make the skin thinner, but also increase the thickness of the skin, making the skin firmer and more elastic, and changing to younger.
Does laser freckle hurt?
In fact, laser freckle removal is a minimally invasive beauty method, which does little harm to the skin. You may feel a tingling sensation during laser freckle removal, which is generally within our acceptable range. For some women who are afraid of pain, local anesthesia can be used to make the treatment easier.
3 laser freckle can be completed in just one treatment?
Laser freckle 1 can't be done after the course of treatment. Generally, laser speckle removal needs about 1 to 5 treatments in clinic, and the interval between two treatments is about 1-2 months. The frequency of laser speckle removal is mainly related to these two factors:
First, the beauty seeker's own conditions
Different skin types and stain types have different laser treatment times, and those with large stain area and dark color have more treatment times.
Second, the choice of laser instruments
At present, there are many laser devices for freckle removal, such as carbon dioxide laser and color light. Different laser equipment will have different treatment time.
Pigmented spots on superficial skin, such as freckles and blue-black tattoos, usually only need 1-3 times to achieve satisfactory results, while nevus OTA usually needs about 5 times of treatment (every time is more than 3 months apart). Pigments in the dermis, such as brown-blue nevus of zygomatic region, respond well to laser, and generally need 3-4 times of treatment, but there will be a pigmentation period of 1-2 months at the initial stage of treatment, which is darker than before treatment, so we must wait patiently for the pigment to subside.
4 Pigmentation represents treatment failure?
Pigmentation is a common adverse reaction after laser treatment, and the mechanism is still unclear. Most experts believe that this phenomenon belongs to the secondary pigmentation after inflammation, which may be related to individual factors such as excessive sun exposure and dark skin color after treatment.
Pigmentation after laser speckle removal is a normal phenomenon. Avoid the sun as much as possible after treatment, and take vitamin C orally to relieve pigmentation, which will generally subside after half a year.
Can laser freckle completely cure chloasma?
After many treatments, laser can really have a good therapeutic effect on freckles, senile plaques and other spots, but freckles are a disease closely related to heredity, so there is a possibility of recurrence after treatment in theory; After the treatment of senile plaque, some beauty seekers may relapse.
As for chloasma, laser is the most commonly used method to treat chloasma at present. Although there is no guarantee of cure, most beauty seekers are still effective.
6 Will laser freckle leave scars?
Because the laser with a specific wavelength can reach the diseased pigment tissue through epidermis and dermis, it only acts on pigment particles, and the epidermis of the skin will not be damaged basically, so it will not leave scars on the skin.
Laser with different wavelengths can be selectively absorbed by pigments with different colors in the skin. For example, at night, use a flashlight to shine things in the house through the glass window, and the glass is not damaged. In other words, laser freckle is a treatment done inside the skin.
Moreover, the area of the laser beam is very small, and it passes through the skin in a very short time of milliseconds and microseconds, so the heat loss of the laser to the epidermis is extremely small, which is also the original difficulty of leaving no scars on the epidermis.
7 will it rebound after laser freckle is cured?
The so-called "rebound" usually refers to the phenomenon that the curative effect is repeated, the effect is obviously reduced or the pigmentation is deepened after a short period of treatment due to the imprecise or unstable treatment.
Laser freckle removal is independent, which does not mean that there can be no spots in the future. If the body is in an "unbalanced" state for a long time, the spots formed by endocrine factors may grow back without paying attention to sun protection and skin care and internal adjustment.
8 Laser freckle removal is only important for therapeutic instruments and therapists?
Therapeutic instruments and therapists are dominant, but postoperative nursing care is very important to ensure curative effect and reduce recurrence.
First of all, after laser surgery, the treatment site may be red and swollen to varying degrees. This phenomenon is normal. As long as the ice is applied in time, it can be relieved, so don't panic.
Second, it is best not to use cosmetics within one week after operation. Aspirin and alcohol (including skin care products containing alcohol) are strictly prohibited. Do not crush or rub the treated area. Washing your face with water is the best choice.
Finally, sun protection. In the process of scabbing and shedding, you must do a good job of sun protection, go out as little as possible, or go out with an umbrella.
The diet is light, and the curative effect can be better after phototherapy combined with repair products.
Patients with chloasma will have enhanced local skin melanin processing ability, leading to an increase in melanin particles. Therefore, the treatment of chloasma should choose some drugs that inhibit tyrosinase activity, such as tranexamic acid, glutathione, vitamin C, vitamin E and so on. If there is stagnation of liver-qi, you can properly cooperate with some Chinese patent medicines for soothing the liver and regulating qi, and do a good job of sun protection on this basis, and then cooperate with the use of whitening drugs, including medical cosmetics and cosmeceuticals, such as vitamin C essence and tranexamic acid essence. However, laser treatment of chloasma is prone to serious pigmentation, and the anti-black ratio of laser treatment is very high. It is suggested that patients should be treated with oral and topical drugs first, and then with local laser treatment for some plaques that are difficult to eliminate.
First of all, let me explain that senile plaque and chloasma are definitely two different concepts!
First, the causes of senile plaque and mitigation measures
In the process of metabolism, the human body will produce a substance called "free radical", which is lipofuscin. This pigment keeps accumulating on the surface of human body, and the fat in the body is easy to be oxidized. With the increase of age, this lipofuscin will become more and more obvious to form obvious spots and plaques!
For senile plaque, we can't directly curb its appearance, we can only alleviate it! Avoid long-term sun exposure and abnormal substance stimulation, adjust the fat content in the diet, and take vitamin E, fresh green vegetables, carrots, potatoes, leeks, Chinese cabbage, etc. And strengthening your own exercise can effectively prevent the appearance of age spots!
2. Causes and solutions of chloasma
1. Causes of chloasma
(1) imbalance of yin and yang in human body
Stagnation of liver qi will cause blood stasis in the eye skin, while weakness of spleen and stomach and deficiency of qi and blood will also cause damp heat in the body to rise to the face, thus forming chloasma. At the same time, the dispersion of yang caused by deficiency of kidney yang will also cause blood to accumulate on the face and promote the formation of chloasma.
(2) Hormones increase during pregnancy
Many women's pregnancy leads to an increase in the secretion of androgen and progesterone in the placenta, so chloasma often appears symmetrically distributed on both cheeks, but most women will return to normal after childbirth, so chloasma on their faces will naturally be alleviated or disappeared.
(3) drug action
Women who take contraceptives for a long time are prone to chloasma. In addition, taking drugs such as hypertension, diabetes, chronic hepatitis and tuberculosis will also increase melanin due to the increased tyrosinase activity, and will also produce chloasma on the face over time. There is also a love of food with strong light sensitivity, such as celery, parsley, carrots, etc., which is also easy to cause chloasma.
(4) Other factors
Improper use of cosmetics will deepen and accelerate the formation of chloasma, and many irregular living habits, such as smoking and drinking, staring at the computer for a long time, reversing the schedule of work and rest, and insufficient sleep time for a long time, will lead to the formation of chloasma.
2. How to prevent chloasma?
(1) Reduce long-term exposure.
On sunny days, you should try to wear a sun hat, sun hat or sun umbrella when you go out, and apply sunscreen on exposed skin to prevent sun in time.
(2) Choose cosmetics carefully
Try to reduce the number of make-ups. If you must make up, try to use cosmetics with natural ingredients, remove makeup thoroughly in time, and keep pores unblocked.
(3) Eat more fresh fruits and vegetables.
Maintain regular eating habits, eat more fresh fruits and vegetables, and supplement your body with rich natural vitamins. At the same time, minimizing spicy and irritating foods such as coffee, onions, garlic, ginger and peppers will also help reduce the formation of facial chloasma.
(4) Drink plenty of water
Drinking more than 800 ml of water every day can effectively accelerate the detoxification and metabolic function of the body, thus keeping the skin tender and achieving a good freckle removing effect.
First, let's explain age spots and chloasma.
Absolutely two different concepts!
Spot-treated
First, the causes of senile plaque
In the process of metabolism, the human body will produce a substance called "free radical", which is lipofuscin. This pigment keeps accumulating on the surface of human body, and the fat in the body is easy to be oxidized. With the increase of age, this lipofuscin will become more and more obvious to form obvious spots and plaques!
Formation and solution of chloasma
1. The formation of chloasma
1 imbalance of yin and yang in human body
Stagnation of liver qi will cause blood stasis in the eye skin, while weakness of spleen and stomach and deficiency of qi and blood will also cause damp heat in the body to rise to the face, thus forming chloasma. At the same time, the dispersion of yang caused by deficiency of kidney yang will also cause blood to accumulate on the face and promote the formation of chloasma.
Hormones increase during pregnancy.
Many women's pregnancy leads to an increase in the secretion of androgen and progesterone in the placenta, so chloasma often appears symmetrically distributed on both cheeks, but most women will return to normal after childbirth, so chloasma on their faces will naturally be alleviated or disappeared.
3 Women who take contraceptives for a long time are prone to chloasma. In addition, taking drugs such as hypertension, diabetes, chronic hepatitis and tuberculosis will also increase melanin due to the increased tyrosinase activity, and will also produce chloasma on the face over time. I also like to eat food with strong light sensitivity, such as celery, parsley and carrots.
Improper use of cosmetics will deepen and accelerate the formation of chloasma, and various irregular living habits such as smoking and drinking, staring at the computer for a long time, reversing the schedule of work and rest, and long-term lack of sleep time will lead to the formation of chloasma.
The question is coming, how to get rid of chloasma?
Keywords suit the remedy to the case, internal cause formation, drinking Chinese medicine for conditioning,
For the spots that have been formed, the pigment is extracted with liquid medicine.
Then excrete melanin and repair the skin, that's all.
Those who specialize in this can consult and see if they are interested. Thank you for your trust!
With the increase of age, various spots often appear on the face. Many people who are recruited are people who love beauty, which seriously affects their own image and causes great psychological burden and mental stress. How should we treat them? Specifically, you can use the following methods:
Causes and solutions of senile plaque: a substance called "free radical", namely lipofuscin, will be produced during metabolism. This pigment is constantly accumulating on the surface of the human body, and the fat in the body is easily oxidized. With the increase of age, this lipofuscin will become more and more obvious, and finally form obvious spots and plaques! We can't directly curb the appearance of senile plaque, we can only alleviate it! And we must avoid long-term sunlight exposure and stimulation of abnormal substances, and usually take more foods containing vitamin A, vitamin C, cysteine and methionine. Or grinding or freezing surgery to remove senile plaque, the effect is very good.
If it is formed in a short time, the color is light and the edge is not clear, you can choose a light spot product to fade it; If it takes a long time to form, the color is dark and the edge is clear, the liquid medicine can be removed, and the larger area should be carried out by stages, and the operation will continue after the scab is removed.
It should be noted that: due to the slow metabolism and poor repair ability of general senile plaque patients, it is recommended to use Quzhongzhou brand freeze-dried powder to accelerate metabolism before scar removal, and use products to repair ice crystals and light spots after scar removal, which can accelerate skin repair and achieve better results.
Causes and solutions of chloasma;
The common internal causes of chloasma are:
1, endocrine disorder;
2, liver function detoxification is not good;
3. There are problems in gynecology;
4. Long-term oral contraceptives;
5. Long-term exposure.
Solution:
1, try to wear a sun hat, goggles or umbrella when going out, apply sunscreen to the exposed skin, and do a good job of sun protection on the skin in time.
2. It is forbidden to use "quick-acting freckle cream" and skin care products containing hormones, lead, mercury and other harmful substances.
3. Maintain regular eating habits, eat more fresh fruits and vegetables, and supplement rich natural vitamins. Reducing spicy food such as coffee, onion, garlic, ginger and pepper will help to reduce the formation of facial chloasma.
4. Drinking more than 800 ml of water every day can effectively accelerate the detoxification and metabolic functions of the body, thus keeping the skin tender and achieving a good freckle removing effect.
5. Quit bad habits, such as smoking, drinking and staying up late. Pay attention to rest and ensure adequate sleep.
If you want to remove freckles, you must not rush for success. It is very important to find the right method and stick to it. It can completely remove freckles and reproduce healthy and fair skin.
Some women will find that a small area of patches will appear on their faces at first, turning dark black, but after a period of time, these small patches will deepen in color, forming yellowish brown patches, and the area will expand, mostly distributed in facial positions such as the back of the nose, eyes and cheeks, which will affect the compactness and face value of facial skin. This kind of spot, we call it "senile plaque", many people think that senile plaque only exists in people over 60 years old, but it is not. After the age of 43, when menopause begins, senile plaques may form.
The formation of senile plaque is closely related to menopause. We know that menopause is characterized by low estrogen secretion and menstrual disorder, which easily leads to endocrine disorders. When the secretion of estrogen in the body is low, the body's self-metabolism ability is reduced, and the function of cell tissue is weakened, which will lead to the oxidation of fat in the body, which may lead to senile plaques. If such pigment is deposited on the cell body, it will also lead to the formation of senile plaques.
The long-term deposition of pigment in the deep skin will lead to the gradual deepening of senile plaques. Age spots will not only accelerate skin aging, but also have a negative impact on endocrine, leading to more serious endocrine disorders and weakened organ function, thus affecting health.
In fact, senile plaque is not as difficult to treat as we thought, especially for people who have just appeared senile plaque. Grasping the three points, we can gradually eliminate pigmentation from our lives, thus diluting senile plaques and alleviating skin aging.
Make yourself a cup of healthy water.
Formula: freckle-removing deer fetus powder 5g, honey 5g and medlar 3g.
Production: put the freckle-removing deer fetus powder into warm water, and then add honey, medlar and so on. , with warm water about 250ml.
Efficacy: This self-made cup of health water can fully absorb crude protein and total saponins contained in deer fetus, inhibit tyrosinase activity, reduce pigment synthesis, reduce pigment metabolism pressure, reduce pigmentation, reduce the occurrence and excretion of pigment from the root, and reduce the generation of senile plaques.
Avoid the sun
Under the irradiation of sunlight, the process of exposure can easily lead to pigmentation, which in turn can easily lead to the appearance of senile plaques. In particular, some people like sunbathing, which can easily lead to the appearance of senile plaques.
Dietary pattern
Many women like to eat sweets or some snacks, which is actually bad for their health. Eating too many snacks is not only the accumulation of toxins, but also one of the reasons for the long spots on the face. If you want your skin to be smooth and delicate, then your diet should be light. This is good for the health of the skin.
Age-related spots are substances called "free radicals (oxidative free radicals)" produced by the human body in the process of metabolism, that is, lipofuscin pigments, which accumulate on the surface of the human body to form age-related spots. Senile plaque is a sign of human visceral aging, indicating that cells have entered the aging stage. Therefore, senile plaque is the information of visceral aging, and its appearance is not isolated, often accompanied by other visible aging indicators, forming an aging image.
Chloasma is a pigmented skin disease that is common in the face, especially in women. At first, it is usually symmetrically distributed in zygomatic process and forehead, with different sizes, irregular shape, clear boundary, yellowish brown or light black, flat on the skin, which is not hindered by hand caressing. Over time, it extends around the nose and lips, and the color deepens, forming a brown butterfly-shaped plaque, which is often aggravated in spring and summer and fades after winter.
Causes of chloasma
1. Hormone changes during pregnancy
During pregnancy, the endocrine changes greatly, and the secretion of estrogen and melanocytes increased. Estrogen can promote melanocytes to synthesize melanin, while progesterone can promote the transport and diffusion of melanin, which can play a coordinating role, leading to a large number of melanin deposition in epidermal cells and chloasma.
2. Gynecological diseases
Some chronic diseases, especially gynecological diseases, such as menstrual disorders, dysmenorrhea, adnexitis of uterus, infertility and so on. , often occurs, and may be related to endocrine disorders such as ovary, pituitary and thyroid.
Sunlight is an important factor.
Ultraviolet light can activate the activity of tyrosinase, which is the proliferation of melanocytes in the irradiated area, thus increasing the production of melanin.
4. Cosmetics can cause chloasma
Cosmetics can cause chloasma, which may be related to some ingredients in cosmetics, such as linoleic acid oxide, citric acid, hydrate, heavy metals, preservatives, spices and so on. Especially inferior cosmetics are more harmful.
5. Electromagnetic radiation
Air pollution, smog, automobile exhaust, dust, electromagnetic radiation from computers, mobile phones and televisions will all lead to decreased skin resistance. In addition, the destruction of the ozone layer makes the skin receive too strong ultraviolet rays, which also increases the secretion of melanin.
6. Drugs or certain diseases
Oral contraceptives, phenytoin sodium and other drugs, chronic adrenal insufficiency, diabetes and so on. It can also induce chloasma.
Nursing focus
1. Pay attention to sun protection and use all kinds of cosmetics with caution.
Do not use "quick-acting freckle cream" containing harmful substances such as hormones, lead and mercury. These cosmetics have too many side effects, which can seriously lead to disfigurement.
2. Pay attention to endocrine regulation, keep a happy mood and get enough sleep.
Nervous system, endocrine system and digestive and excretory system are the three systems of human body, which maintain the normal operation of various functions of human body. These three systems are interrelated and interdependent, and once they are out of balance. Will affect the whole. Because chloasma is directly related to human endocrine system, the prevention and treatment of chloasma should focus on freckle removal and endocrine regulation.
3. Stay away from all kinds of radiation.
Including various display screens, fluorescent lamps, X-ray machines, ultraviolet radiators, etc. These bad stimuli will have consequences similar to strong sunlight, even greater than the damage caused by sunlight, leading to increased pigmentation.
No matter what spots, they all affect the face value.
Chloasma, which generally appears in women during pregnancy, is easy to grow around cheekbones, forehead and mouth, showing left-right symmetry, so it is also called butterfly spot. After 40 to 50 years old, women's ovarian function gradually declines, and chloasma is prone to occur due to insufficient hormone secretion.
Senile spots: The surface is rough, mostly waxy brown patches or papules, which are generally caused by tissue aging.
At present, the commonly used freckle removal method is to use laser freckle removal combined with daily diet and skin care habits to gradually remove spots on the face.
Some people are prone to relapse after freckle removal, mainly for three reasons:
The nature of spots determines
Such as freckles, senile plaques, pigmented nevus and other qualitative spots, have stable properties and are not easy to recur after removal; However, sunburn, pregnancy spots, chloasma and other active spots that are easily affected by external factors are easy to recur.
Thermal damage caused by laser speckle removal
Generally, the activity of melanocytes in yellow people is stronger than that in white people, which is more likely to lead to secondary pigmentation and make faded spots turn black again or dark brown.
Improper postoperative care
Failure to do a good job in sun protection after operation is also one of the factors leading to recurrence.
A little older, skin metabolism slows down, endocrine disorders will easily lead to long spots, senile spots, chloasma and so on are qualitative spots, these kinds of spots are relatively stable, not easily shaken by external factors, the recurrence rate after laser removal is small, and the effect is obvious!
If you want to get rid of qualitative spots, the best way is laser freckle, and skin care should be done after operation to prevent blackening. However, it is not recommended to use medical beauty methods for senile plaques, which are easy to appear repeatedly!
If you dare not try medical beauty, you can also try to use freckle cream. Although it can't be completely removed, it can minimize spots and improve skin quality.
And whether there are long spots or not, sun protection must be done well, especially for people with long spots. If you don't do a good job of sun protection, the spots will be aggravated, and it will be more difficult to dilute and remove them!
With the growth of age, because of the endocrine disorder of human body, or the pressure of working environment and working mood, some senile spots will appear on the face more or less.
Miao Yunshui, chief physician of Wenzhou Yixing Skin Beauty Center, has been engaged in laser beauty for more than 0 years 10, with rich clinical experience and professional knowledge of medical aesthetics, and has successfully realized the butterfly dream of beauty lovers.
At present, laser is a very effective method to remove senile plaque. Its principle of action is: laser removal of senile plaque can rupture pigment cells in a very short time, and then through blood circulation and lymphatic circulation metabolism, so as to achieve the purpose of desalination or removal of senile plaque.
Before laser removing senile plaques, a professional skin detector is used to make a reasonable treatment plan according to the types of plaques and skin conditions. In order to confirm the freckle safety of beauty seekers and ensure that there is no thermal damage to the skin during the treatment, beauty seekers are relaxed and comfortable during the treatment, and there is no pressure to relax the treatment. After treatment, the skin will be firmer and smoother than before, and the skin quality will be improved.
