Women love beauty, once the spots, acne, wrinkles want to get rid of them, so more and more women favor laser beauty. But after the laser beauty is not everything is fine, many women after the laser beauty, see their own beautiful face again and feel happy, but often forget that after the laser needs careful care. The skin doctor reminds that if you don’t take care of yourself after the laser, the effect will be greatly reduced. Post-operative <4 hours: alert to the danger of infection What is the first thing to do after laser surgery? It is to prevent infection! Dong Xiuqin, chief physician of the Department of Dermatology of Guangdong Provincial People's Hospital, stressed that under normal circumstances, the sebaceous membrane of the skin has a strong defense function, but within 4 hours after laser cosmetic surgery, the skin area undergoing surgery has not yet re-formed its own defense mechanism. Therefore, this 4 hours is a dangerous period, easy to produce infection, must avoid entering the environment that may cause pollution. In addition, the skin metabolism will be accelerated after laser cosmetic surgery, which requires more water, so you should drink more water to maintain the humidity. Some hospitals will provide sterile skin care film, this dressing generally contains collagen, or promote the epidermal growth factor ingredients, in addition to isolate the post-operative skin exposure to the outside world, but also to promote the effect of wound healing. However, it should be reminded that the skin care film used within 4 hours after surgery must be a medical skin care film, which is tested for bacteria. Those skin care films on the market that have not undergone strict bacterial testing and are used for care should not be used indiscriminately to prevent infection. After surgery > 48 hours: only do simple skin cleaning After laser cosmetic surgery, can you still clean your skin as usual. Dong Xiuqin said, generally speaking, within 4 hours after the operation is not to do any skin cleaning. And it takes 4 hours for the skin to re-form its own protective mechanism after surgery. But this skin protective film is formed under the stress state and can only play the most basic protective ability. Therefore normal cleansing is generally not possible for 48 hours. If there is a need to clean the skin, a special activated charcoal cleaning film can be used and applied to the skin to absorb the dirt. Normal cleansing can only be performed after 48 hours after the surgery. However, in the choice of skin cleansing products, Dong Xiuqin said that it is recommended not to use regular skin cleansing products within 6 days after surgery, and it is better to use skin cleansing products without additives under the advice of doctors. It is strictly forbidden to use cleansers with the effects of oil removal, fruit acids, scrubbing, deep purification, etc. Post-operative > 6 days: Basic skin care Avoid stimulation Six days after surgery, some moisturizing products can be used appropriately. If you want your skin to recover from laser surgery without too much external stimulation, it is best to use only care restorative and therapeutic skin care films and creams, etc. Skin care products with certain efficacy, such as whitening and antioxidant, may have pharmacological ingredients that can easily stimulate the delicate skin that has just grown back. These irritations are likely to cause allergic reactions in the skin. In addition to making the skin infrared, if it causes inflammation, it may also cause hyperpigmentation, making the skin tone darker or re-forming discoloration, which is not worth the loss. It is worth mentioning that although collagen helps to restore the skin’s elasticity and re-glow, it does not necessarily mean that its use after laser surgery is beneficial and harmless. Dong Xiuqin warned that a small number of people have allergic reactions to collagen, so it should be used with caution. In addition, the use of whitening and masking products is prohibited throughout the laser cosmetic procedure, and the use of makeup is also strictly prohibited. The most important point after laser beauty is to pay attention to sun protection. Dong Xiuqin said that ultraviolet rays have been an important culprit in the production of skin problems such as pigmentation, and after laser treatment, the skin is in urgent need of conditioning stage, more sensitive to external influences, if not do a good job of sunscreen and maintenance, then, skin problems are likely to re-emerge. Sun protection should be used throughout the entire laser cosmetic procedure. However, since a thin layer of scab will form on the skin after the laser, which usually takes about a week to fall off, no sunscreen should be used during this period, so try to avoid exposure to UV rays. If you want to go out, it is best to wear a hat or umbrella. In addition, try to avoid traveling from 11:00 am to 3:00 pm, when the sun is the most intense and the UV rays are the strongest, which will make the skin easily sunburned. Six days after surgery, you can use sunscreen products that are suitable for you and have natural ingredients, generally SPF 25 or above is sufficient. It is recommended that you choose a medical sunscreen skin care product that is suitable for you under the guidance of your doctor. It is also important to pay attention to the moisturizing of the skin. What should I pay attention to in my diet after having laser treatment? Some people think that laser beauty has nothing to do with diet, after doing laser or love to eat what to eat, but this idea is very wrong, Dong Xiuqin said, because most of the laser beauty is for melanin, so after the laser, must pay attention to hydration, do not let the skin in a dehydrated state. Secondly, the diet should be kept as light as possible, it is best to eat less beef, pickled foods, shrimp, crab, wine, coffee and other stimulating foods. You can eat more food containing vitamin C and vitamin E, such as lemon, orange, grapefruit, kiwi, etc.. Or take vitamin C according to your doctor’s instruction, which is helpful to prevent skin problems from rebounding.
