1, pay attention to the regularity of life, the combination of work and rest, relaxation, peace of mind, avoid mental tension, excessive stress; 2, eat more vegetables and fruits, control the intake of sweets, animal fats, fried, spicy food and strong wine, to reduce the factors that stimulate sebum secretion; 3, choose the appropriate cosmetics, avoid using creams containing too much oil ingredients, and choose a good moisturizing effect of the solution or micronized thin lotion, thus keeping the skin clean and the pores clear. Patients with acne can also alleviate the condition and play an auxiliary role in treatment by using acne cosmetics (cosmetics containing salicylic acid, glycolic acid and other keratolytic agents), etc. Some female patients like to use makeup such as foundation to cover up existing acne, but inappropriate makeup can aggravate the lesions. 4. Pay attention to sun protection because UV rays can lead to epidermal thickening and aggravate the keratinization of the sebaceous ducts of hair follicles, leading to the deterioration of acne. Patients with acne should avoid strong sun exposure and choose sunscreens that do not cause acne. For patients with more oily skin, water or gel-like sunscreen products can be used, with chemical sunscreens being preferred. You should go to a regular hospital dermatology department as early as possible and treat under the guidance of a doctor. Do not purchase your own medication for treatment, because if the medication is not properly selected, it will instead aggravate acne, such as corticosteroids; for the scar formed by acne, patients can go to the dermatology department of a regular hospital and choose to undergo treatments such as fruit acid peeling, microdermabrasion and fractional laser.
