On the compatibility of vitamin C and glycolic acid
The way of skin care, the combination of ingredients, is related to the efficacy and suitability of the skin. Vitamin C and glycolic acid are both commonly used ingredients in skin care, but whether they can be mixed and used is quite popular.

Vitamin C has strong antioxidant properties, can help the skin resist aging, remove dullness, promote collagen production, and make the skin bright and energetic. Glycolic acid, which belongs to fruit acids and the like, can exfoliate the skin, make the skin smooth, and can promote the metabolism of the skin and improve the skin quality.

To know whether the two can be mixed, its properties should be known first. Vitamin C is acidic and remains stable and active in a specific pH environment. Glycolic acid is also acidic, and its acidity is relatively strong. When the two are mixed, the acid-base environment in which they are located will suddenly change, or the stability of vitamin C will be damaged. If the stability is lost, the antioxidant activity of vitamin C will be reduced, and the efficacy will be greatly reduced.

Furthermore, glycolic acid has the effect of exfoliating, thinning the stratum corneum of the skin, causing skin sensitivity to improve. Although vitamin C is beneficial, it may cause discomfort to sensitive skin. Mixing the two, when applied to the skin, may exacerbate the irritation of the skin, redness, itching in the light, rash or molting in the severe.

If it is properly prepared, it is not impossible to mix. When blending, it is necessary to precisely control its ratio and adjust the pH to a suitable environment to maintain the stability of vitamin C. At the same time, it is advisable to do a skin test before use, and apply it to a small area of skin to observe its reaction. If there is no discomfort, the scope of use can be gradually expanded.

In short, the use of vitamin C mixed with glycolic acid has advantages and disadvantages. Users need to know their skin type in detail and be cautious. If you don't know it, use it rashly, and it may damage the skin.
