For now, laser acne removal is a faster and safer medical treatment that is easy and painless and can quickly enhance the skin’s self-healing as well as regenerative abilities with significant clinical results. However, there are also some disadvantages, such as laser acne removal requires multiple courses of continuous treatment, and the cost of each treatment is more. Before undergoing laser acne removal, it is recommended to choose a regular large hospital in order to ensure the effectiveness of the treatment. The formation of acne is the result of a high secretion of sebaceous glands, keratinization of the follicular opening, secondary infection with Propionibacterium acnes and an inflammatory response. The principle of laser acne treatment is to use laser light to kill the acne-causing bacteria and effectively stimulate the skin so that collagen can be regenerated to achieve the effect of acne removal. Laser acne removal can improve the secretion of sebaceous glands and the keratinization of the hair follicle opening, and later, after the appearance of acne marks, the redness removal principle of laser can also be used to improve acne marks. In addition, laser can stimulate collagen tissue proliferation and remodeling of the skin to improve acne pits; for hyperplastic acne pits, fractional laser can be used to improve the method. After laser acne repair, patients should try to reduce direct sunlight, and do not use stimulating cosmetics, while supplementing vitamin E and eating more fresh fruits and green vegetables, which can effectively lighten acne scars.
