The Compatibility of Glycolic Acid Toner and Niacinamide Essence
The nourishment of the husband's skin depends on the suitability of all products. Today, it is of great concern to everyone whether glycolic acid toner and niacinamide essence can be used together.

Glycolic acid is a fruit acid and the like, and has the effect of rejuvenating the skin. It can exfoliate the surface layer, make the skin smooth and delicate, promote metabolism, and increase skin luster. Niacinamide essence is effective in skin repair, oil control and acne suppression, and brightening the skin tone.

However, when the two are used in combination, their compatibility must be checked. Glycolic acid is acidic, and niacinamide may change under specific acid-base environments. If the pH value is uncomfortable, niacinamide may be converted to niacin, causing skin intolerance, redness and tingling.

To see if the two can be used together, first check the skin's tolerance. If the skin is sensitive and weak, use them together rashly, and you may cause discomfort. You can try it locally first to observe the skin's reaction. If you apply a small amount of product behind the ear or under the jaw, you can use it gradually after a few days, if there is no abnormality.

In addition, the order of use is also exquisite. Usually use glycolic acid toner first, wait for the skin to absorb, and then use niacinamide essence. In this way, the risk of interaction between the two may be reduced.

Furthermore, the frequency of use also needs to be considered. When using it for the first time, the frequency should be low, and it should be adjusted after the skin adapts.

In summary, glycolic acid toner and nicotinamide serum can be used in combination. Then you must check the skin condition carefully before use, and abide by the method of use, in order to ensure skin health and nourish the effect.
