On the Suitability of Using Niacinamide and Glycolic Acid in Order
All skin care methods and the order of materials used are related to efficacy and skin comfort, which cannot be ignored. Glycolic acid is a type of fruit acid, which is active in nature, can exfoliate, open pores, rejuvenate skin luster, and promote cell renewal. Niacinamide has many wonderful effects, which can even skin tone, shrink pores, and strengthen skin barrier. Both are wonderful skin care products, and they are used in sequence, which is quite exquisite.

If glycolic acid is applied first, it will loosen and thin the stratum corneum, and the permeability of the skin will increase greatly in a short period of time. At this time, if niacinamide is used urgently, niacinamide may be more likely to penetrate due to changes in the skin barrier However, although nicotinamide is mild, it may cause discomfort in some people with sensitive skin, or due to the fragile state of the skin at this time, such as tingling and redness.

If nicotinamide is applied first, it first strengthens the skin barrier and builds a protective wall for the skin. Subsequent use of glycolic acid can slow down the exfoliation force and make the skin gradually adapt. In this way, it may reduce the possibility of skin discomfort, and the effects of both must be taken into account.

But the nature of the skin, your mileage may vary. Oily skin, sebum secretion is strong, tolerance is good, first glycolic acid and then nicotinamide, or it can get efficient skin rejuvenation effect without obvious discomfort. For dry and sensitive skin, it is appropriate to use pre-nicotinamide to protect its barrier. When using glycolic acid again, it is also necessary to slow down and thin it, and closely observe the skin's reaction.

In general, the use of nicotinamide and glycolic acid in combination, first nicotinamide and then glycolic acid, can take care of the effect and skin comfort. However, skin care, the most important thing is to know the nature of the skin, and do it cautiously, in order to get the best fruit and keep the skin healthy and moist.
