Usage of glycolic acid
Glycolic acid is mild in nature and has unique effects. It is very popular in the field of skin care. Its usage is diverse and needs to be carefully selected according to individual skin type and needs.

If you are a first-time user, it is recommended to start with a low-concentration product in view of the irritation of glycolic acid. After cleansing, take an appropriate amount of glycolic acid-containing products and apply them evenly to the face with gentle movements, avoiding the skin around the eyes and lips. In the initial stage, you can use it once or twice a week, and then increase the frequency of use moderately according to the skin's adaptation. For example, after the skin adapts, it can be gradually increased to three times a week. During this process, if the skin experiences discomfort, you should stop using it immediately and consult a professional.

For people with oily and combination skin, glycolic acid can effectively clean up oil and dirt in the pores, and improve the greasy and rough condition of the skin. Appropriate amount of glycolic acid toner can be used to infiltrate a cotton pad, and gently wipe the face and T-zone and other oily areas to achieve secondary cleansing and oil control.

For dry and sensitive skin, be sure to do a good job of moisturizing the skin before using glycolic acid products. You can apply a layer of moisturizing essence or lotion as a base first, and then apply a small amount of glycolic acid products to reduce the irritation to the skin. And, the frequency of use should not be too high, once a week is appropriate.

In addition, after using glycolic acid products, it is necessary to strengthen sun protection measures because the skin is more sensitive to ultraviolet rays. When going out, apply sunscreen, wear a sun hat and sunglasses to avoid direct exposure to the sun to prevent skin damage.
