On the compatibility of vitamin C serum and glycolic acid
The way of skin care, everyone seeks its effect and safety. Vitamin C serum and glycolic acid are both commonly used in skin care, but whether the two can be used together is quite doubtful.

Vitamin C serum has antioxidant properties. On the skin, it can help resist the damage of free radicals, promote the production of collagen, brighten the skin, reduce wrinkles and light spots, and has outstanding effects. Glycolic acid belongs to the class of fruit acids, which can lightly exfoliate, clear pores, flatten the skin, increase metabolism, and make the skin tender and smooth.

If the two are compatible, it is necessary to be cautious. Vitamin C is acidic, and glycolic acid is also acidic. The combination of the two may cause the local acidity of the skin to be too strong. The skin has its own acid-base balance. If it is out of balance, it will cause skin discomfort, such as redness and tingling; if it is severe, it may damage the skin barrier, sensitize the skin, and cause many skin diseases.

However, it is not absolutely impossible to use both. If the skin has good tolerance, it can be tried on a small scale first. Apply a little mixture of the two behind the ear or on the inside of the arm. After observation, if there is no adverse reaction, it can be gradually used on the face. And it should be used at a low concentration to start, step by step. Use glycolic acid first, wait for the skin to adapt for a while, and then use vitamin C serum, and the interval should be slightly longer. In this way, it may reduce the risk of skin

Furthermore, when using during the day, strict sun protection is required. Because the two may increase the skin's sensitivity to light, if there is no sun protection, it is easy to cause skin damage and pigmentation.

In general, vitamin C serum and glycolic acid are compatible, which has advantages and disadvantages. Use it properly, or get a complementary effect; use it carelessly, it may hurt the skin. Therefore, users should make a careful choice according to their own skin condition, and consult a professional when necessary.
