Discussion on the Compatibility of Niacinamide Essence and Glycolic Acid
Today there are niacinamide essence and glycolic acid, both of which are commonly used ingredients in skin care, but whether they can be used in combination, many people have doubts.

Niacinamide has good skin care effect. It can regulate the oil secretion of the skin, improve the oil glow of oily skin, and achieve a refreshing state. And it has the power of repairing the skin barrier, enhancing the skin's resistance to external stimuli, and making the skin tougher. In addition, it is also effective in whitening light spots, inhibiting melanin production and transport, gradually reducing pigmentation, and brightening skin tone.

Glycolic acid is a fruit acid, with small molecules and strong penetration. It can remove the aging keratin on the surface of the skin, accelerate the metabolism of keratinocytes, speed up the renewal of the stratum corneum on the surface of the skin, and then make the skin smoother and more delicate. At the same time, it can promote the synthesis of collagen in the dermis, increase skin elasticity, and reduce fine lines.

However, it is necessary to be cautious to use both. Glycolic acid is acidic, which can lower the pH of the skin and cause the skin to be in a relatively acidic environment. Niacinamide is stable in a specific pH range. If used in combination with glycolic acid, which is too acidic, when the pH value is lower than a certain level, niacinamide may change to niacin. Niacin is more irritating, or cause skin redness, tingling, itching and other uncomfortable symptoms.

If you want to use both, you can try it before small pieces of skin. And the frequency of use should not be too high. You can use it every few days at the beginning, and then adjust it after the skin adapts. When using, first clean the skin with gentle cleansing products, pat it lightly until dry, apply nicotinamide essence first, and then apply glycolic acid products thinly after it is absorbed. If the skin is uncomfortable during use, you should stop using it immediately and consult a professional dermatologist or skin care expert.

In short, although nicotinamide essence and glycolic acid have their own skin care effects, you need to pay attention to their compatibility when using them together. Use it reasonably according to your own skin condition to achieve the ideal skin care effect and protect the health of your skin.
