On whether it is appropriate to use vitamin C and glycolic acid together
Today's skin care people often doubt whether vitamin C and glycolic acid can be used together. The two have their own functions in skin care.

Vitamin C has antioxidant effects, can help the skin resist the damage of free radicals, promote collagen production, make the skin bright and uniform in color. Glycolic acid is a type of fruit acid, which can loosen the bond between keratinocytes, promote the shedding of the stratum corneum, make the skin delicate, and can open the door of skin metabolism.

However, when using both, be careful. Vitamin C is acidic, and glycolic acid is also acidic. The superposition of the two may cause the local acidity of the skin to be too strong. The skin has its acid-base balance. If it is out of balance, it may cause discomfort, such as tingling, redness, and itching. Sensitive skin is more susceptible to its effects.

And vitamin C is chemically active. When it encounters glycolic acid, it may react chemically, which will damage its skin care effect. If the antioxidant activity of vitamin C may decrease, the keratin renewal function of glycolic acid may change.

If you want to use it together, you can try it in a small range and at a low concentration at the beginning. After observing the skin's reaction, if there is no discomfort, gradually expand the range and increase the concentration. When using it, it is appropriate to divide the time. For example, use vitamin C during the day for antioxidant skin care, and use glycolic acid at night to promote keratin renewal. In this way, you can avoid its harm and improve its growth to achieve better skin care effect. In skin care, your mileage may vary, carefully observe the characteristics of the skin, and use it cautiously, which is the right way.
