On the Compatibility of Glycolic Acid and Niacinamide
In the way of skin care, the compatibility of ingredients is crucial. Glycolic acid is a type of fruit acid, which has the power of rejuvenating the skin, can exfoliate, promote skin metabolism, and make the skin smooth and shiny. Niacinamide can improve the skin barrier, reduce yellow gas, and inhibit melanin transport, which is beneficial for brightening the skin tone and maintaining stable skin. Both are excellent skin care products, but whether they can work together is really a concern for beauty lovers.

Or glycolic acid and niacinamide should not be used together. Gaiinglycolic acid is acidic, and niacinamide may be converted into niacin in an acidic environment. Niacin is highly irritating, or causes skin redness, itching, tingling and other discomfort. And since glycolic acid has the power to exfoliate, it makes the skin relatively sensitive. If nicotinamide is added, the skin may be irritated.

However, there are also different opinions. Studies have shown that if the concentration of the two is appropriately blended and the skin is well tolerated, it can also be used together. For example, start the skin rejuvenation process with low-concentration glycolic acid products first, and then add nicotinamide products after the skin adapts. Or use it at different times, with niacinamide for protection and brightening during the day, and glycolic acid for deep rejuvenation at night. This operation may enable the two to play a synergistic effect, which not only achieves the purpose of rejuvenating and brightening the skin, but also avoids excessive irritation.

In general, the compatibility of glycolic acid and niacinamide cannot be generalized. Users need to be cautious according to their own skin conditions. If the skin is sensitive, try it on a small scale first, and observe its reaction step by step. Skin care matters, scientific and prudent, can find the appropriate method, get the ideal effect.
