Acne on the face is an inflammatory disease due to localized hair follicles and sebaceous glands. To eliminate acne quickly, the most important method is laser treatment, and paying attention to daily skin care, diet, and lifestyle habits can also help eliminate acne. The pulsed laser can effectively induce the inflammation of the hair follicle to subside and accelerate the blood circulation of the blood vessels around the follicle to promote the metabolism of the inflammation. For larger cysts, photodynamic treatment is an option. For scarring, laser treatment can be effective in flattening it. Laser treatment for acne can target only the skin in the acne area and will not affect the surrounding normal skin. Laser treatment is also very safe and does not require any incision during the treatment process, and does not leave a large incision, and the recovery time is relatively fast. After the treatment is completed, the probability of acne recurrence is low. In addition, you can also help treat acne by applying vitamin A acid cream, adapalene gel and recombinant bovine basic fibroblast growth factor gel for anti-keratinizing, anti-inflammatory and anti-bacterial effects. Patients with acne should take good care of their skin, wash their face with warm water every day, and choose appropriate cleansing products for skin cleansing. After having laser treatment, you should follow medical advice to avoid getting water on the trauma surface and avoid using cleansing products to avoid infection. Although laser treatment can quickly eliminate acne, it is likely to cause hyperpigmentation after recovery. In addition, some patients may experience subcutaneous bruising after laser treatment, which is a more dangerous condition and can easily leave scars on the treatment area. Therefore, if it is not necessary, patients are advised to improve their acne gradually, not to rush, to relax and to follow medical advice.
