On the Mixing of Glycolic Acid Toner and Niacinamide
Recently, in the way of skin care, people often ask: Can glycolic acid toner and niacinamide be mixed? This is a key question related to skin care.

Glycolic acid toner has unique effects. It can accelerate the metabolism of the stratum corneum of the skin, make the old keratin fall off, make the skin glow, and can penetrate deep into the pores and remove blockages. It is beneficial for improving skin problems such as acne and acne. However, its acidic properties, if used improperly, or cause skin discomfort, sensitive skin should be especially cautious.

Niacinamide is also a good skin care product. It can effectively regulate skin oil secretion, shrink pores, and make skin more delicate. At the same time, it can inhibit melanin production, even skin tone, and improve skin brightness. Long-term use helps to enhance skin barrier function and make skin healthier and more stable.

As for whether the two can be mixed, it needs to be carefully considered. From the perspective of chemical principles, glycolic acid is acidic, and niacinamide is stable in a specific pH environment. When the two are mixed, if the pH changes greatly, or niacinamide is converted into niacin, niacin is more irritating to the skin and can easily cause redness, tingling and other uncomfortable symptoms.

However, there are also studies showing that if the concentration of the two is appropriate and the skin is well tolerated, moderate mixing may play a synergistic effect. For example, gently wipe the skin with glycolic acid toner first, and wait for it to be fully absorbed, and then use products containing nicotinamide at intervals for a few minutes, so that you can avoid adverse reactions and gain better skin care results.

Therefore, if you want to mix glycolic acid toner with nicotinamide, you should try it on a small area of skin first. Observe for a few hours to a day, and if there is no abnormal reaction in the skin, you can gradually expand the scope of use. And during use, you need to pay close attention to the skin condition. If there is any discomfort, you should stop immediately and seek professional skin care advice. In short, skin care should be done with caution in order to maintain skin health and achieve the desired skin beauty effect.
