On the Hazards of Overuse of Glycolic Acid
Glycolic acid is quite commonly used in skin care, but the dosage should not be careless.

Looking at the structure of the skin, the outer layer of keratin has protective properties. If glycolic acid is used moderately, it can promote keratin renewal, make the skin glow, delicate and smooth. However, if it is overused, the harm will appear immediately.

First, the skin is prone to allergies. Glycolic acid is irritating to a certain extent. Excessive use of it will damage the skin barrier. It is originally a barrier against foreign objects. If it is damaged, various external stimuli, such as dust mites, pollen, etc., can easily invade the skin, causing redness, itching, and even red rashes, and allergies.

Second, the risk of skin dehydration. Glycolic acid can speed up the metabolism of the skin. Although this has the effect of promoting exfoliation, if overused, the stratum corneum becomes thinner and the water retention ability plummets. The skin seems to have lost its water storage device, and the moisture is lost a lot, so it feels tight and dry. After a long time, wrinkles are also easy to occur.

Third, the risk of burning the skin. High concentration of glycolic acid, if used improperly or in excess, can directly burn the skin. In light cases, the epidermis is red, swollen and painful, in severe cases, the skin is ulcerated, and after healing, it may leave scars and damage the face.

Therefore, if you want to use glycolic acid for skin care, you must carefully review the characteristics of the skin, follow the doctor's advice or product instructions, and use it in moderation. Don't be greedy for quick results, causing all kinds of harm to the skin, and regret it.
