The laser causes certain damage to the skin structure during the treatment process. Proper post-operative skin care helps to reduce post-treatment complications, and at the same time can synergize the effects of the laser to promote skin regeneration and repair while treating disease and beauty, which is of great significance, mainly in the following aspects.
1 .Reducing postoperative skin reactions
According to the immediate reaction of the skin cold wet compress or ice with a towel wrapped around the ice after laser skin, such as after treatment skin color whitening, ice time is about 30min, such as only congestion, redness, cold wet compress time is 15min, in the process to avoid friction skin. If erythema, swelling, oozing blood obvious, available 3% boric acid solution, collagen mask, containing compound glycyrrhetinic acid cold compress film local wet compress. After wet compress, apply moist burn cream, and then 2-3 times a day until the skin wound is completely repaired.
2. Prevent infection and reduce inflammatory reaction
In order to prevent postoperative skin infection, if necessary, gentamicin injection or mupirocin ointment can be applied thinly to the traumatic surface.
3. Promote wound healing
At present, alkaline fibroblast growth factor, epidermal growth factor and rehabilitation new solution are commonly used, whose main function can promote the healing of burn wounds and improve the quality of healing, and if the epidermis is broken after laser surgery, it can be sprayed on the wounds to promote healing.
4. Promote skin regeneration and repair the basal layer and other skin structures
Laser can damage the sebaceous membrane, stratum corneum, brick wall structure and water channel protein of the skin to varying degrees, so it is very necessary to use suitable medical skin care products for effective skin care (moisturizing, sunscreen, reducing local skin erythema, stinging, burning and other inflammatory reactions, and repairing damaged skin) within 3-6 months after treatment. Unlike traditional cosmetics, medical skin care products are special cosmetic products between drugs and cosmetics, which have both the auxiliary therapeutic effects of drugs and the characteristics of cosmetics, such as safety, stability, comfort and effectiveness.
5. Prevention and treatment of hyperpigmentation
Dark-skinned patients have a higher risk of hyperpigmentation, but most of them are mild and fade on their own within 3 months. Pay attention to sun protection and topical application of hydroquinone preparations and L-vitamin C serum can help, and more serious cases can be systematically taken orally or topically with drugs that inhibit melanin formation.
6, sun protection
The skin is in a hypersensitive state after laser treatment, and the basal layer melanocytes may produce a large amount of melanin after stimulation by light, resulting in postoperative skin pigmentation, sun protection is an important part of post-laser care, the main measures are as follows.
① Minimize sun exposure, especially avoid going out during the peak UV period, such as 10 am to 4 pm.
② Play umbrella, sun hat and sunglasses when going out.
③Avoid UV reflected from water, snow, desert, road etc.
④Do not use photosensitive drugs, food and disinfectant and germicidal agents, etc.
⑤ Use sunscreens. To use sunscreen products with high safety and good sun protection effect. Sunscreens on the market before the month are broadly divided into: chemical UV absorbers, physical UV shielding agents, biological sunscreens. Because the physical sunscreen mainly through the reflection, scattering ultraviolet radiation to achieve the purpose of sun protection, the composition is mainly: kaolin, titanium dioxide, zinc oxide, talcum powder, etc.. They are mild, non-toxic, not absorbed by the skin, and not easy to cause allergies. Therefore, physical sunscreens are preferred after laser surgery. The sunscreen chosen after laser surgery should be UVB sun protection index ( SPF) >30; UVA protection factor ( PFA) >++.
7. Diet
The role of diet on skin repair should not be ignored. Protein, fat and sugar are essential nutrients for the skin, vitamins and trace elements can affect the normal metabolism and physiological functions of the skin, such as: B vitamins, folic acid can increase pigmentation: vitamin C, vitamin A can reduce pigmentation; certain trace elements, such as copper can contribute to melanin production. Therefore, eat less spicy food after laser surgery, and eat more food rich in vitamin C and vitamin A. For example, eat more fruits and vegetables, as well as food containing iron, zinc and other trace elements such as lean meat, fish, beans, cabbage, radish, etc., and pay attention to drinking more water. To promote the repair of the skin.
