Glycolic acid, a fruit acid and the like, has the power of exfoliation. It can loosen the adhesion between keratinocytes, make the old waste keratin fall off, make the skin surface renewed, and rejuvenate and shine.

Vitamin C, a strong antioxidant. It can resist the invasion of free radicals on the skin, prevent oxidative damage to the skin, and protect the skin from ultraviolet rays and environmental pollution. At the same time, it can inhibit tyrosinase activity, block melanin production, achieve the effect of whitening light spots, and also promote collagen synthesis to maintain skin firmness.

Glycolic acid opens the skin channel, making vitamin C easier to penetrate and absorb, strengthening whitening and antioxidant power; the antioxidant properties of vitamin C can relieve the irritation caused by glycolic acid, and protect skin health.

When used in combination, be careful. When starting to use, it is advisable to test the sensitivity first, and apply a small amount behind the ear or on the inside of the forearm to see if there is redness, swelling and itching. And from a low concentration and frequency, such as glycolic acid, choose a concentration of 2% - 5%, and use it every 2-3 days; vitamin C at a concentration of 5% - 10%, once a day at the beginning. When the skin adapts, gradually increase the concentration and frequency. Apply glycolic acid first when using it, and apply vitamin C after drying. And strict sun protection is required during the day, because both increase the skin's sensitivity to light.
