In the field of skin care, people often ask whether glycolic acid can be used with nicotinamide. Glycolic acid, as an alpha-hydroxy acid, has a unique effect. It can accelerate the metabolism of the skin, promote the exfoliation of old waste keratin, and then make the skin smoother and more delicate. It can also improve the dullness of the skin and make the skin glow.

And nicotinamide, its role should not be underestimated. It can effectively reduce skin inflammation and is quite friendly to acne muscles. At the same time, it can also enhance the skin's barrier function, improve the skin's water-locking ability, and keep the skin hydrated at all times.

In terms of ingredient characteristics, the two can theoretically be used together. But in practice, extra caution is required. Due to the irritation of glycolic acid, if the skin is more sensitive, rashly mixing the two is very likely to cause skin discomfort, such as redness, tingling and other symptoms.

Therefore, it is recommended to try it on a small area of skin first. For example, you can apply a small amount of the mixed product behind the ear or inside the arm and observe it for 24 to 48 hours. If there is no adverse reaction, then gradually expand the scope of use. In this way, you can give full play to the advantages of the two synergistic skin care on the premise of ensuring skin safety.
