On the Compatibility of Vitamin C and Glycolic Acid
If you want to know whether Vitamin C and Glycolic Acid can be mixed, it should be investigated. Vitamin C has strong reducing properties, and it can help antioxidant, light spot whitening, and promote collagen production in the skin. Glycolic acid, a fruit acid, can exfoliate, rejuvenate the skin, smooth fine lines and enhance luster.

However, when mixing the two, be careful. Vitamin C is acidic, and glycolic acid is also an acid. The superposition of acidity may cause the skin to fail to tolerate it, causing discomfort, such as tingling, redness, and itching. And the stability of vitamin C is not good. When it encounters glycolic acid, it may cause a chemical reaction, which will damage its effect, or even cause harmful things.

If you want to use both of these, you can do it in time. Use vitamin C during the day, with its antioxidant energy, to resist external harm; use glycolic acid at night, while the skin is repairing, to promote keratin renewal. If you must mix it, you should try it on the skin on a small scale first, to see if there are any adverse reactions, if not, you can use it gradually. And after use, when it is tremendous support for moisture, it protects the skin's barrier.

In short, vitamin C and glycolic acid have their own strengths, and when used properly, they can have the effect of beautiful skin; if used carelessly, it will hurt the skin. Therefore, when mixing, be careful to ensure the safety of the skin.
