"On the Mixture of Glycolic Acid and Niacinamide"

There are various methods for skin maintenance. Among them, glycolic acid and niacinamide are both good skin care products, but whether they can be mixed is worth exploring.

Glycolic acid belongs to the fruit acid category, which has the ability to exfoliate, can make the skin exfoliate, make the skin glow, and can promote skin metabolism, help improve skin texture, and make the skin more delicate and smooth. Niacinamide can effectively inhibit the transfer of melanin to the surface skin after production, achieving whitening effect, and at the same time can strengthen the skin barrier, reduce skin moisture loss, and keep the skin hydrated.

However, if the two are mixed, it needs to be handled with caution. Glycolic acid is acidic, and niacinamide may undergo hydrolysis reaction under specific acidic environments to generate niacin. Niacin may cause skin irritation, causing skin redness, itching and other uncomfortable symptoms. If you want to mix the two, first test the skin's tolerance. Try the product containing low-concentration glycolic acid and niacinamide on a small area of skin first, and observe it for a few hours to a day. If there is no adverse reaction to the skin, you can gradually expand the use area. And at the beginning of mixing, the frequency of use should be low, such as once or twice a week. After the skin adapts, increase the frequency moderately.

In addition, the order of use is also exquisite. You can use milder nicotinamide products first, and then use glycolic acid products after they are absorbed, which may reduce the risk of skin irritation.

In short, the mixed use of glycolic acid and nicotinamide, although it may be able to achieve both effects, it is necessary to operate carefully according to your own skin condition to achieve the best condition of skin care and protect the health of the skin.
