As long as you don't want to get acne when you are young, getting acne is depressing enough. What is even more depressing is the acne scars and pits left after acne. This will help you solve acne scars. Its treatment method can be based on the depth of acne, considering chemical skin exchange or dermabrasion surgery for treatment. Generally speaking, superficial acne scars can be treated with different concentrations of fruit acid. Its theoretical basis is that fruit acid reduces the cohesion of keratinocytes, directly exfoliates epidermis, removes pigment layer and rough epidermis, and helps to form a new stratum corneum, making skin more tender and smooth. For deep acne scars, it is necessary to use dermabrasion surgery to achieve the ideal effect. It used to be a popular surgical method to grind off epidermal skin with die machine, but it is difficult to control the grinding depth correctly, and now it has been gradually replaced by pulsed laser. Pulsed laser uses the principle of instantaneous high heat to remove the surface epidermis very accurately, and after repeated polishing, a smoother surface can be obtained. Generally speaking, after dermabrasion surgery, there will be more serum secretions in the wound in the first two or three days. Artificial skin and antibiotic ointment can be used for nursing to protect the wound from scab. Four days after operation, sebaceous gland cells will proliferate rapidly and produce new skin. About seven to ten days after the operation, the wound can be completely healed. At this time, due to the red and tender skin of the treatment site, there is no normal skin pigment protection. If exposed to the sun, it is easy to produce stains. Therefore, it is necessary to prohibit sun exposure and increase sun protection within two or three months after operation until the skin returns to near normal. Three months after operation is the time to evaluate the effect of dermabrasion. If the pockmark is still uneven, you can accept laser dermabrasion again. If there is unfortunate pigmentation, we must wait patiently, and most of them can achieve the effect of reducing pigmentation within half a year after surgery. In short, fighting acne in adolescence is a necessary process for every young person. As long as you keep your face clean, stay away from high-calorie food, relax and don't stay up late, I believe you can get away with it without any sequelae. If the battle against acne unfortunately fails, resulting in uneven lunar surface, only qualified plastic surgeons can turn to chemical skin changing or laser skin grinding to achieve satisfactory results.
