The most important part of acne skin care is to cleanse, moisturize and protect the skin from the sun. In terms of cleansing, the most common mistake that patients make is to wash their faces until the skin is tight. In fact, strong alkaline cleansing products will make acne worse by increasing the reproduction of P. acnes bacteria, while moisturizing cleansers will improve acne. It is best to use a gentle cleansing product and wash several times a day to gently remove excess oil without tightening. For acne patients, medication often causes skin flaking and irritation, so use a moisturizing lotion with more water. Oily and acne-prone skin can be aggravated when the skin is too dry, which can easily affect the periorbital keratinization process. It is recommended to use products containing fruit acids or salicylic acid. Skin can also be regularly treated with fruit acid revitalization, which is a safe, effective, economical and convenient non-pharmaceutical treatment for acne. A large body of medical literature both at home and abroad reports that fruit acid skin treatment can normalize the skin’s keratinization process, effectively treating acne; promote epidermal renewal, rejuvenating the skin; and assist in the natural moisturizing effect of cells. Sunscreen for oily and acne-prone skin can be a non-comedogenic and refreshing oil-controlling sunscreen lotion made for acne-prone skin.
