On the feasibility of using nicotinamide after glycolic acid toner
Those who have questions now doubt whether nicotinamide can be used after using glycolic acid toner. The way of skin care, the combination of various products, is related to the effect and the suitability of the skin.

Glycolic acid is a fruit acid, which has the power of exfoliation, which can make the old and waste exfoliation on the surface of the skin fall off, rejuvenate the skin, and promote the absorption of subsequent skin care products. However, its nature is slightly stronger, or it may cause skin sensitivity, and the skin needs to be nourished after use.

Niacinamide is quite popular in the field of skin care. It can reduce yellowness, smooth skin tone, and strengthen the skin barrier and inhibit sebum secretion.

If nicotinamide is used immediately after glycolic acid toner, the skin tolerance should be tested. Those with strong skin may be able to tolerate it, and the combination of the two may rejuvenate and brighten the skin. However, for those with delicate and sensitive skin, glycolic acid has caused slight damage to the skin. At this time, nicotinamide may increase discomfort and cause redness and tingling.

Therefore, if you want to use nicotinamide after glycolic acid toner, it is appropriate to test the sensitivity first. Take a little nicotinamide and apply it behind the ear or under the chin, and observe it for several hours. If there is no discomfort, it can be used on the face. And for initial use, a small amount should be gradually increased to give the skin the opportunity to adapt.

In short, your mileage may vary when it comes to skin care. It is not feasible to use nicotinamide after glycolic acid toner, but it must be based on skin tolerance and careful to achieve skin care and beauty.
