The compatibility of nicotinamide and glycolic acid is the key to skin care. The combination of nicotinamide and glycolic acid has attracted much attention in the field of skin care. However, whether the two can be used together is the concern of many beauty lovers.

Niacinamide is a derivative of vitamin B3. Its effect on skin care is quite significant. It can strengthen the skin barrier, reduce water loss, and improve skin color, making the skin even and shiny. In addition, nicotinamide has anti-inflammatory effects and is beneficial for ordinary skin inflammation.

Glycolic acid is a fruit acid and the like. Its molecules are small and can easily penetrate into the stratum corneum of the skin. The power of glycolic acid is to promote the renewal of the stratum corneum, loosen the connection between keratinocytes, make the old keratin fall off, and then make the skin smooth and delicate. And it can stimulate the production of collagen and enhance skin elasticity.

As for the compatibility of the two, many studies have their own claims. Some studies have shown that nicotinamide and glycolic acid may react when used in combination. When the two meet, nicotinamide may be converted into niacin, which is highly irritating to the skin, or causes redness, tingling and other uncomfortable conditions.

However, some studies have also pointed out that if the two are used in an appropriate concentration and in a proper manner, they can also be used in combination. In the low concentration state, the possibility of interaction between nicotinamide and glycolic acid is low, and the irritation to the skin can be controlled. And the two effects are complementary, glycolic acid promotes keratin renewal, nicotinamide enhances the skin barrier, or can synergistically achieve better skin care effect.

If you want to use nicotinamide and glycolic acid, you should be cautious. Test a small amount of the product behind the ear or on the local skin first to see if there is any discomfort. And at the beginning of use, the concentration should be low and the frequency should be small. After the skin adapts, you can adjust it as appropriate. In this way, you can enjoy the skin care effects of both, and avoid the risk of skin damage.
