On the order of use of glycolic acid and niacinamide
The way of skin care, the order of ingredients, is related to the recognition of efficacy. Glycolic acid (Glycolic Acid) and niacinamide (Niacinamide) are both commonly used ingredients in skin care, but their use sequence is quite exquisite.

Glycolic acid belongs to the class of fruit acids and has the ability to exfoliate. It can loosen the old keratin on the surface of the skin, promote skin metabolism, make the skin glow, and improve skin texture and reduce fine lines. However, it is slightly stronger, improper use, easy to cause skin sensitivity.

Niacinamide has various effects. It can effectively inhibit the transfer of melanin to the epidermis, brighten skin tone, and improve dullness. And it can enhance the skin barrier function, reduce the skin moisture loss, and make the skin firmer and smoother.

As for the order of use of the two, if the skin has strong tolerance, you can use glycolic acid to open the door of skin renewal first. Because after exfoliation, the skin absorbs subsequent nutrients better. At this time, using nicotinamide can make its effect easier to play. The two complement each other, and the effect is more obvious in brightening the skin tone and improving the skin texture.

However, if the skin is more sensitive, use nicotinamide to stabilize the skin barrier first. After nicotinamide enhances the skin's resistance, then use glycolic acid to reduce the irritation of glycolic acid to the skin and reduce the risk of sensitivity. In this way, you can also reap the effect of good skin care step by step.

In general, the order of use of glycolic acid and nicotinamide depends on the individual skin condition. Or first glycolic acid and then nicotinamide to exert the synergistic effect of exfoliation and nourishment; or first nicotinamide and then glycolic acid to ensure stable tolerance of the skin. Only by applying skin policies can you achieve the wonders of skin care and achieve a beautiful skin.
