On the concentration of glycolic acid used by the skin

The skin is smooth and delicate, which is related to the human complexion. The concentration of glycolic acid in skin care is the key.

If the concentration of glycolic acid is too low, the effect will not be obvious. The skin is like a gauze, unable to fully nourish the medicinal power. Although it is harmless, it is difficult to achieve the purpose of rejuvenating the skin and improving the dull and delicate skin. It is still difficult to travel on a shoal, and it is difficult to reach a distance.

If the concentration is too high, it is like a fierce medicine attacking the body. The fragile barrier of the skin is unbearable. It may cause redness, swelling and tingling, or even molting allergies, which is counterproductive. This is still too hasty, haste is not enough.

Therefore, those who make good use of glycolic acid to protect the skin must carefully observe the characteristics of the skin. For dry skin, the stratum corneum is thin, and a lower concentration, such as 2% - 5%, should be selected to slowly recuperate and gradually start the process of rejuvenation. For oily skin, the stratum corneum is slightly thicker, you can try a concentration of 5% - 10% to clean pores and balance oil. For sensitive skin, you need to be more cautious. Try it on a small scale of 1% - 3% first, observe its reaction, and then make a decision.

When using glycolic acid, it should be done step by step. When using it for the first time, the frequency should be less, such as once a week, when the skin adapts, and then increase as appropriate. It is also necessary to pay attention to protection. After daytime use, sunscreen must be applied to prevent UV damage.

In general, the concentration of glycolic acid used by the skin should be moderate and suitable, and it should be in line with the skin's characteristics, so as to achieve the beauty of skin protection and skin beauty, so that the skin can always maintain youthful luster.
