On the Method of Glycolic Acid Whitening
If you want to use glycolic acid to remove the dark color of the skin, you must clarify the method and do it cautiously. Glycolic acid has the power of exfoliating and promoting the metabolism of the skin, but it is strong in nature. If used improperly, it will hurt the skin.

At the beginning of use, cleanse the skin first, so that the face is scale-free and greasy. Then take an appropriate amount of glycolic acid products and apply it gently to the face, avoiding the eyes, lips, and tender areas around the mouth. When using it for the first time, it should be sparse and thin. Try it on a small part of the skin to see if there is any discomfort, such as tingling, redness, and itching. If there is no abnormality, the range can be gradually expanded. < br When the skin is first adapted, it should be used once a day. When the skin tolerates it, it can be increased to once a day. However, it must not be too frequent, so as not to damage the skin, cause the barrier to lose solidification, and reproduce other diseases.

After use, the protection is also heavy. Glycolic acid makes the skin sensitive to light, so after daytime use, it must be applied with sunscreen to resist the invasion of ultraviolet rays, prevent the return of dark colors, and can be applied with mild moisturizing products to nourish the skin and moisturize it, making the skin smooth.

In addition, people with sensitive skin, pregnant women and human performers of virtual idols should consult a doctor before use, and follow the doctor's advice. In this way, using glycolic acid to remove the dark color can keep the skin healthy and achieve the wish of whitening.
