An Analysis of Whether Glycolic Acid Toner and Niacinamide Can Be Used Together
Recently, many beauty lovers often ask whether glycolic acid toner and niacinamide can be used together. Both are commonly used ingredients in the field of skin care, but it is necessary to study their suitability when used together.

Glycolic acid, a type of fruit acid, has excellent exfoliation effect. It can loosen the connection between keratinocytes, accelerate the shedding of the old waste stratum corneum, and then promote skin metabolism. Long-term use can make the skin smoother and more delicate, and it is also effective in improving dull skin tone and fading pigmentation. However, because of its certain irritation, people with sensitive skin may need to use it with caution.

Niacinamide is a derivative of vitamin B3. In skin care, it is outstanding. First, it can effectively inhibit the transfer of melanin to the surface skin, achieving whitening and brightening effects; second, it can enhance the skin barrier function, reduce skin moisture loss, and make the skin long-lasting hydration; third, it is also beneficial for improving skin oil secretion and shrinking pores.

As for whether the two can be compatible and matched. From a chemical point of view, glycolic acid is acidic, and niacinamide is relatively stable in chemical properties. Under normal circumstances, the combination of the two will not cause adverse reactions. However, in actual use, some key points still need to be paid attention to. If the user's skin is already sensitive, or if you try this combination for the first time, it is recommended to try it on the local skin first to observe whether there are any discomfort symptoms such as redness, swelling, itching, etc. If the skin experiences tingling and other abnormalities during use, you should stop using it immediately.

In the order of use, you can first clean the skin with mild cleansing products, then take an appropriate amount of glycolic acid toner, pat it on the face with a cotton pad or directly with your hands, and wait for it to be fully absorbed. After a while, take a skin care product containing nicotinamide. In this way, it may reduce the possibility of skin discomfort.

To sum up, in most cases, glycolic acid toner and nicotinamide can be used together and can exert a variety of skin care effects. However, users must make a reasonable choice according to their own skin conditions and try it carefully to achieve the best skin care effect and maintain healthy and beautiful skin.
