The Effect of Glycolic Acid on Pigmentation
There were doctors in ancient times who tried to study the disease of skin pigmentation. I saw that everyone was worried because of dark spots and brown spots on the face and neck, and the appearance was damaged.

The doctor heard the name of glycolic acid, so he explored its properties. Knowing that glycolic acid is mild and has unique properties. It can loosen the connections between keratinocytes, make the old keratin shed, and accelerate the renewal of the skin's surface.

Find a number of patients with pigmentation. First observe the skin, and note the pigment distribution and color depth in detail. This is the state "before glycolic acid improves pigmentation". Then, apply glycolic acid preparations at appropriate concentrations to the patient's affected area, in sequence. Or apply it to the face, or apply it to the neck, and advise the patient to follow the doctor's advice and not to increase or decrease the dosage or duration.

After ten months, look at the patient's skin again. However, the dark spots gradually fade, the brown spots become lighter, and the skin gradually becomes more uniform. This is the scene of "after glycolic acid improves pigmentation".

The function of covering glycolic acid is to promote keratin metabolism, make the new cells at the bottom of the skin move up in an orderly manner, inhibit tyrosinase activity, and reduce melanin production. Therefore, it can make the pigmented skin regain its luster, relieve the patient's worries, and restore its moist and smooth face. Doctors have also become famous for exploring this way, benefiting more people who are troubled by pigmentation.
