How can I remove acne marks? First of all, let's understand the types of acne scars: acne scars can be mainly divided into two types: spots (that is, acne marks) and scars (depressions or protrusions). Among them, spots are divided into red and black. Erythema is caused by inflammation of cells in the original acne area, which leads to vasodilation. However, after the acne disappears, the blood vessels will not contract immediately, forming a temporary erythema with a flat red color. Skin will be redder when the temperature rises or when you exercise. This erythema is not a scar, and it will gradually fade in 4 to 6 months. Black spots are pigmentation after acne inflammation, which leaves a dark and dirty color in places longer than red acne, making the skin dull. In fact, these blacks will gradually disappear over time, so impatient people have to apply some ointment that can remove melanin or accept fruit acid rejuvenation and vitamin C introduction. This kind of stain and pigmentation will disappear naturally after a long time, so it is generally a temporary fake scar, not a real scar. Of course, erythema and melanin precipitation will take some time to disappear, otherwise the contracted blood vessels will not contract, and the redness will not retreat; Melanin can't disappear unless the pigment that should have been transported away by cells is transported away. Generally speaking, this kind of false scar will disappear automatically in about half a year on average, but some people will take longer than the average time because of their different physical fitness, such as one year or even two years. People who can't wait can only apply A- acid, azalea acid, fruit acid or L- vitamin C for external use, or accept fruit acid rejuvenation, dye laser, pulse phototherapy and vitamin C introduction to accelerate the disappearance of spots. True scars are divided into concave holes and hypertrophic scars. Real scars don't disappear automatically, only after treatment by dermatologists. Pits and scars are common. When the acne inflammation is too strong and there is too much collagen in the dermis, it may leave a pit because of the collapse of the dermis. Many acne patients like to squeeze acne by hand. If they are squeezed improperly, it will greatly increase the chance of suppurative infection, and it is easy to turn small acne and small acne into big acne, thus leaving scars. Once the pit is created, it will not disappear automatically. You have to save it by laser dermabrasion. Hypertrophic scar, commonly known as "crab's foot swelling", is usually determined by congenital constitution, which is the most difficult to treat and easy to recur. This kind of scar is just the opposite of concave scar. This is a very thick scar. In the place where the acne has grown, there are obvious red protrusions, and the appearance is red and swollen. What's more, it will grow up slowly because of scratching or external stimulation. It often happens to patients with special physique. Because the fibroblasts in the dermis of these patients are too active, they overreact during wound healing. As a result, the dermis is not depressed, but raised after being damaged by inflammation, and becomes hypertrophic skin tissue hyperplasia. The problem of acne scar covers the epidermis, dermis and subcutaneous tissue of the skin, and the consequences include skin damage, tissue defect and scar formation, which not only causes skin appearance defects, but also affects the normal tissue structure of the skin. In order to improve the problem of acne marks and scars, it is necessary for doctors to diagnose and evaluate different types of scars to determine the treatment plan. Treatment of black acne scar: a) use L-C skin care products or L-C ultrasonic introduction: brighten skin color and promote skin collagen production; B) Use skin care products containing fruit acid: simultaneously treat acne and improve acne scars, promote the exfoliation of old and waste keratin, help skin renew, improve pigmentation after acne and fade dark spots; C) Efficient whitening products or whitening treatment: slow down the production of deep melanin and accelerate melanin metabolism. Treatment of red pockmark: Pulsed light can also increase the collagen in the dermis, so that the depression is no longer obvious and the pores become larger, so it is also suitable for skin with erythema and slight pits. B) Use skin care products containing fruit acid: simultaneously treat acne and improve acne scars, promote the exfoliation of old and waste cuticles, help skin renew, and improve pigmentation after acne; C) Purification treatment: anti-acne, pore removal prevention, and intensified anti-acne treatment: a) Fruit acid rejuvenation: peeling off the cuticle of the skin with high concentration to promote the exfoliation of the aged cuticle. Accelerating the renewal of keratinocytes and a small number of epithelial cells, promoting the proliferation of elastic fibers in dermis, has a good effect on superficial acne scars and can also improve the coarseness of pores, but it takes a lot of courses to eliminate acne scars, but its advantages are safety and few side effects; B) Filling method: implant (such as collagen) is injected to make the concave part bulge and flush with the surrounding skin tissue; C) Pulsed light: Stimulate the proliferation of fibroblasts, thicken the dermis and flatten the pits. At the same time, because pulsed light can stimulate the proliferation of collagen, this method has certain effect on red acne marks and newly generated shallow pits. D) deep skin regeneration treatment: for deep acne, remove pores, dilute acne scars and brighten skin tone; E) Laser dermabrasion: It is suitable for deep pits, and can be performed according to the depth of pits in the skin. It only takes 2~3 times to get good results, and the effect is lasting. However, due to the trauma of laser dermabrasion, it is necessary to cooperate with postoperative maintenance. If the postoperative care is not good, the skin may turn red and black. Treatment of hypertrophic scar: a) local subcutaneous injection: for swelling of crab feet and hypertrophic scar, drug injection is directly injected under the skin of acne scar for treatment. This drug is mainly composed of steroids and has the functions of anti-inflammation and dissolving inflamed tissues. This is the simplest and most effective treatment for hypertrophic scar at present. After several injections, the acne scar can gradually soften, from convex to flat, but the pigmentation of scar tissue can not fade, so there will still be some traces after healing, which can not completely restore the appearance of normal skin. B) Phototherapy, such as laser, such as dye laser, can smooth hyperplastic scars. Some points for attention in the treatment of acne scars: 1. No matter what kind of acne scar is treated, the acne should be cured first, so that the acne will not grow again. Otherwise, the treatment of acne scars and the growth of new acne will not achieve the best results. 2. After treatment, it can be combined with external whitening skin care products and fruit acid products to enhance the curative effect, on the one hand, it inhibits melanin production, on the other hand, it promotes skin metabolism and accelerates melanin elimination. Such as L- vitamin C, androgen, A acid, kojic acid, etc. However, whitening skin care products and fruit acid skin care products are more effective for melanin precipitation, but the effect on reddish acne marks is relatively poor. 3. The mask is also helpful for the recovery of acne marks. On the one hand, the mask can increase the skin surface temperature, generate self-help circulation on the face, and help the skin tone to be even. At the same time, the repair nutrients contained in the mask can be better absorbed by the underlying skin; On the other hand, regular application of facial mask helps to accelerate skin metabolism and help skin repair itself. 4. Pulsed light therapy can be combined with fruit acid therapy and L-C introduction. How to combine it depends on the skin condition at that time. Pulsed light can improve the treatment of spots, especially erythema, because pulsed light can eliminate microvessels. However, due to the different proliferation depths of microvessels in the skin, once they are done, they will be weak and need multiple treatments. 5. After the medical beauty treatment, the most important thing is the maintenance after the treatment. Only by proper maintenance can the effect of the course of treatment be maintained for a long time. 6. First of all, pay attention to sun protection after treatment. A large amount of ultraviolet radiation will cause pigmentation on your convalescent skin, which will make the color of acne scars heavier and stay longer, so it is not suitable for outdoor activities for too long. 7. It is better to choose autumn and winter seasons for the treatment time of fruit acid skin changing or laser skin changing, but if you can do a good job of sun protection, you can actually do it every season. 8. In terms of food, you can add some foods that can help the skin to be even and accelerate skin healing, such as lily, mung bean, tremella, lotus seeds, coix seed and so on. It has the function of clearing fire and making skin even. Nuts include almonds, walnuts, sesame seeds and other vegetables and fruits containing vitamin C and vitamin A, such as cauliflower, cabbage, green vegetables, tomatoes, lemons, strawberries, kiwis and so on.
