Summer freckle-removing, toxin-expelling and beauty-nourishing tea
Theme: motherwort tea
Ingredients: 6 grams of motherwort, a little brown sugar, green tea.
Exercise:
1, Leonurus heterophyllus is washed with cold water first, and the green tea is brewed with boiling water for a few seconds, and the water is drained, and the tea leaves are reserved for later use;
2. Put motherwort and tea leaves in a pot or pot of boiling water, cook for about 5 minutes, add brown sugar and stir, then cool to make tea.
This product can relieve summer heat and remove blood stasis.
Reminder:
First, motherwort promotes blood circulation to remove blood stasis, yin deficiency and blood deficiency.
Traditional Chinese medicine believes that motherwort tastes bitter and cool, enters pericardium and liver meridian, and has the functions of promoting blood circulation, removing blood stasis, regulating menstruation and promoting diuresis. Can be used for treating irregular menstruation, dystocia, postpartum blood halo, abdominal pain due to blood stasis, metrorrhagia, hematuria, diarrhea, carbuncle, swelling, sores, etc. , can be taken orally or externally.
It should be noted that female friends with yin deficiency and less blood should avoid taking it.
Second, motherwort can make tea or boil water for external application.
Motherwort tea is made of brown sugar, which has high nutritional value and is rich in riboflavin, carotene, nicotinic acid and trace elements such as manganese, zinc and chromium. It has the effects of enriching blood and benefiting qi, promoting blood circulation and relaxing muscles and tendons, warming spleen and invigorating stomach, removing blood stasis and promoting tissue regeneration. This recipe is delicious and nourishing, and is mainly used for treating postpartum abdominal pain, pressing, lochia, dizziness and tinnitus, pale face, red tongue, thin coating and weak pulse.
Motherwort can also be washed and boiled to help eliminate spots on the face.
Third, pay attention to drinking tea, not on an empty stomach.
The ancients once said? A cup of tea earlier is better than a robber from a poor family? It is not advisable to drink tea on an empty stomach in the morning. Because drinking tea on an empty stomach will dilute gastric juice, reduce the function of gastric acid, hinder digestion, affect the absorption of protein, and easily cause gastric mucosal inflammation.
In addition, drink tea in moderation and avoid drinking too much tea, because tea contains caffeine. Excessive drinking tea can cause anxiety, irritability, insomnia, palpitations and other symptoms, leading to poor sleep, inhibiting gastrointestinal peristalsis, hindering digestion and reducing appetite.
Types and prevention methods of common facial spots in summer
(1) chloasma
clinical picture
It is common in young and middle-aged women, and often occurs symmetrically in the zygomatic and buccal parts of the face, showing a butterfly shape. It can also involve the skin around the forehead, nose and mouth, and chloasma mostly occurs in the sunburned part of the face. Typical lesions are brown or dark brown plaques of different sizes, which are aggravated in spring and summer and weakened in autumn and winter.
According to the distribution of skin lesions, it can be divided into butterfly type, upper face type, lower face type and ordinary type. The stain will change with the passage of time, pregnancy and sun exposure will aggravate the lesion, and the symptoms will gradually decrease after the patient gets old. Chloasma needs to be differentiated from acquired nevus of OTA (ADM), which is sometimes difficult to distinguish, and some patients suffer from both diseases at the same time, so it needs to be carefully distinguished and treated step by step.
The causes of chloasma are complicated, including constitution, ultraviolet rays, hormone levels and oral contraceptives. Recently, more and more studies show that factors such as impaired skin barrier function and skin micro-inflammation play an important role in the pathogenesis of chloasma.
Treatment and prevention
The treatment of chloasma is very difficult, so far there is no effective radical cure. Some treatments of epidermal pigment may be temporarily relieved (such as exfoliative dot matrix laser, fruit acid, etc. ), but it has no effect on deep chloasma and is easy to relapse.
General treatment:
Remove possible causes, strictly prevent sun, change bad skin care habits, and strengthen skin sunscreen and moisturizing. Chloasma caused by birth control pills should be stopped. Keep an optimistic mood and have a good sleep.
Local treatment: hydroquinone and its compound preparation, Qianbaihydroquinone, etc. It is the most commonly used external preparation for chloasma. Others, such as tretinoin, azelaic acid, tretinoin preparations, Chinese herbal extracts, etc., also have certain curative effects.
Systematic therapy:
Vitamin c and vitamin e
Vitamin C can prevent the oxidation process of melanin metabolism and inhibit melanin synthesis. Vitamin E can scavenge free radicals and prevent the oxidation of unsaturated fatty acids in the body. The combined application of the two has a synergistic effect.
glutathione
The molecule contains active sulfhydryl groups, which can inhibit tyrosinase activity, reduce the antioxidant effect of unsaturated fatty acids and scavenge free radicals. It can be combined with oral or mixed intravenous drip of vitamin C to improve the curative effect.
tranexamic acid
Oral tranexamic acid has a good effect on the conservative treatment of chloasma. It can be taken for a long time (6-30 months) with a small dose (250mg twice a day), which usually takes 1-2 months, and the effective rate is 80%. It has become the first choice to treat chloasma in Japan. Its therapeutic mechanism is still unclear. It is worth noting that patients must be told to stop all cosmetic operations that irritate the skin while taking drugs orally, so as to avoid further excessive stimulation of facial skin, especially chloasma. Some people even think that this is more important than drug abuse itself.
Photoelectric therapy:
Q-switched 1064nm Nd :YAG laser: The mode of large spot and low energy is adopted, which has a certain clinical effect and few adverse reactions, but recurrence is common.
Non-exfoliating lattice laser: Its principle is to generate array-like tiny light beams to act on the skin, and the water in the skin tissue absorbs the laser energy, forming a plurality of columnar micro-heat-damaged areas, thus stimulating a series of skin biochemical reactions and destroying melanocytes. Because tissue is not vaporized, only epidermis and hydrous dermis are coagulated, so there are few adverse reactions such as pigmentation after operation.
Treatment: oral tranexamic acid+low energy intense pulsed light +LED red light?
Intense pulsed light:
It is a kind of incoherent light with a wide spectrum, which belongs to ordinary light rather than laser in essence. The principle of treating chloasma is to destroy cells containing melanin and repair skin barrier function through selective photothermal action. Some scholars used intense pulsed light combined with Q-switched1064 nm Nd: YAG laser for treatment, and achieved good long-term results.
Factors such as impaired skin barrier function and skin micro-inflammation play an important role in the pathogenesis of chloasma. Based on this new concept, we should re-examine the treatment of chloasma. The treatment of chloasma should not only treat primary skin lesions, but also rebuild the damaged skin barrier function. Through the reconstruction of barrier function, it is of great significance to reduce skin irritation, eliminate inflammatory reaction, stabilize melanocytes and reduce pigmentation.
The significance of preventing howling:
Strict sun protection and strengthening moisturizing play an important role in preventing chloasma.
(2) Freckles
clinical picture
It belongs to autosomal dominant inheritance, and is prone to school age (different from other points). Skin lesions are common on the face or exposed parts, with isolated light brown to dark brown spots, mostly on cheeks, lower eyelids, nasal roots, upper eyelids, forehead, nasal back, oral cavity, and even widely distributed throughout the face.
After ultraviolet irradiation, tyrosinase activity in melanocytes of freckle skin increased, and a large amount of melanin was produced. Therefore, the relationship between freckles and sun exposure is very significant. The number, size and color of spots depend on the amount of sunlight absorbed and the individual's tolerance to sunlight. There are many freckles in summer, which are dark brown, but they will decrease in autumn and winter.
Treatment and prevention
Traditional treatment:
Including topical drugs (such as hydroquinone cream, tretinoin and rhododendron acid), chemical peeling and cryotherapy. However, these treatments are rarely used because of their low non-selective effect and great damage to epidermis.
Laser therapy:
Frequency doubling Nd: YAG (532 nm) laser, Q-switched ruby laser (694 nm), Q-switched emerald laser (755 nm), etc. , has a very good therapeutic effect, generally only need 1-2 times of treatment to achieve complete elimination. The disadvantage is that the epidermis will be slightly damaged during treatment, and there will be redness and scab after operation, which will take several days to recover.
Due to the skin characteristics of the yellow race, some patients will have a certain degree of pigmentation after treatment, and a few will be more obvious. Generally speaking, laser with longer wavelength, such as 755nm laser, is less likely to form color deposits, while laser with shorter wavelength, such as 532nm laser, is more likely to form color deposits.
Generally speaking, patients with obvious freckles can get ideal curative effect, while patients with fuzzy freckles have relatively poor curative effect.
Intense pulse therapy:
IPL has large facula and high efficiency, and can be used for the treatment of the whole face, with no omission, little pain and slight postoperative reaction. During the treatment, the epidermis will not be damaged, only scabs will be produced, so the construction period is endless, and there is basically no pigmentation after inflammation. The disadvantage is that there are many treatments, and it takes 3-5 treatments to achieve the basic removal effect. However, with the appearance of DPL (narrow spectrum pulsed light), it has better selectivity for pigments and can reduce the number of treatments.
The importance of sun protection:
Sunlight will aggravate the symptoms of freckles, so freckles will be more obvious in summer. ? Spots? Flowers? Spots? After treatment, the grass should be more strictly protected from the sun, because freckles are hereditary, so even if they are completely removed, as long as they are not protected from the sun, they will accumulate enough damage. But it is not a recurrence, but a new one (the new spots can be in the original place or in other places).
(III) Seborrheic keratosis-senile plaque
clinical picture
Commonly known as senile plaque, it is the most common facial stain, which mostly occurs in the elderly after 40 years old. Skin lesions mainly occur on the face, scalp, trunk and upper limbs, with a diameter of 1 mm ~ 1 cm, or several centimeters, light brown to dark brown maculopapules or flat papules, uniform color, smooth surface or slightly papilloma-like, and the surface can gradually increase with age. Generally, the side is slightly more than the front.
Treatment and prevention
General treatment:
0.025~0.05% tretinoin ointment for external use.
Photoelectric therapy:
Frequency-doubled ND:YAG laser (532nm), Q-switched ruby laser (694nm), Q-switched alexandrite laser (755nm) and intense pulsed light have good effects on senile plaques that do not rise above the skin surface. Usually 1-2 times can be completely removed. For those senile plaques that are higher than the skin surface, the best treatment method is CO2 laser, which has a positive effect, but it is necessary to avoid leaving scars after too deep treatment. Some lesions have both flat parts and parts higher than the skin surface, which can be treated comprehensively by combining the above two methods.
Treatment: frequency doubling ND:YAG laser (532nm)?
The importance of sun protection:
The most important factor causing senile plaque is ultraviolet light, and it can even be said that senile plaque is the result of long-term ultraviolet radiation. Therefore, strict sun protection is the most important thing to prevent senile plaque.
(4) Brown-blue nevus
Also known as acquired nevus of OTA, acquired dermal melanocytosis (ADM). Although it is? Mole? , but often with? Spots? Hanging out together and suffering together? Sun exposure? Tired, so I also participated in this article as a good friend.
clinical picture
Most of them are 16~40 years old, which is more common in women after 20 years old. They have typical pigmentation distribution and morphological characteristics, and are mainly found in cheekbones, temporal parts, eyelids and alar parts, and will not involve palates and eyeballs. The lesions are grayish brown, dark gray and dark brown spots, with clear boundaries between circle and ellipse. The size of millet and soybean are isolated and not fused, and distributed symmetrically. 20.9~25% patients have family history.
Treatment and prevention
Laser therapy:
Q-switched ruby laser (694nm), Q-switched alexandrite laser (755nm) and Q-switched frequency doubling ND:YAG laser (1064nm) can be used for treatment, generally 3-5 times, with an interval of more than 3-6 months each time, and the skin lesions can be completely removed. If patients with brownish-blue nevus are accompanied by chloasma, it is suggested to treat chloasma first, so as to avoid stimulating melanocyte activity, aggravating chloasma lesions and reducing the risk of pigmentation after laser treatment.
Significance of sun protection: the occurrence of brown-blue nevus is related to many reasons, but ultraviolet rays will aggravate skin lesions, so we should also strictly prevent sun protection.
