It is often doubtful whether nicotinamide and glycolic acid can be combined with
Niacinamide and glycolic acid. Let's try it out today.

Niacinamide has many benefits for the skin. It can help the skin's barrier solidify, keep moisture intact, and moisturize the skin. It can also smooth the skin's color, lighten pigmentation, remove dullness, and make the complexion glow. It can also reduce the secretion of oil, make the skin refreshing and less oily.

Glycolic acid belongs to fruit acid and the like. Weakly acidic, it can remove the old and waste keratin of the skin, making the stratum corneum thin and orderly, and the skin more smooth and delicate. It can also promote the metabolism of the skin, start the process of cell renewal, and keep the skin youthful. And it can increase the permeability of the skin and make the subsequent skin care ingredients easier to absorb.

However, whether the two can be used in combination needs to be considered in detail. Glycolic acid is an acid, which decreases the pH of the skin. If used in combination with nicotinamide, or causes nicotinamide to hydrolyze into niacin. Niacin is highly irritating to the skin and can make the skin reddish, tingling, itchy, especially for sensitive skin.

However, there are also studies that say that if the purity of nicotinamide is good and the concentration of the two is appropriate, it may not be a big problem to use it at the same time. However, for skin safety, it is advisable to try it before a small area of skin when using it for the first time. Apply one first, and wait for the skin to adapt without adverse reactions, and then apply the other. And the frequency of use should not be high, so as to give the skin a cushioning machine.

In short, whether nicotinamide and glycolic acid are used together or not varies from skin to skin. For dry and sensitive skin, be careful; for oily and well-tolerated skin, you can try it, but you should also pay attention to the skin's reaction. If there is any discomfort, stop using it immediately and consult a professional. In this way, you can protect your skin without worry.
