On the principle of sharing glycolic acid and nicotinamide
The method of skin maintenance, glycolic acid and nicotinamide are often concerned by everyone. However, whether it can be used together, there are different opinions, and it needs to be explored in detail.

Glycolic acid is a fruit acid and the like, which has many wonders. It can penetrate deep into the skin, loosen the connection between keratinocytes, make old and waste keratin naturally fall off, making the skin surface smooth and delicate, like a new life. And it can stimulate the synthesis of collagen, improve skin elasticity, reduce fine lines and wrinkles, and delay the process of skin aging.

Niacinamide is also a good skin care material. It can effectively regulate the oil secretion of the skin and make the oily skin refreshing. It has the power to repair the skin barrier and enhance the skin's ability to resist external stimuli. At the same time, it can inhibit the transfer of melanin to the epidermis, achieve the effect of whitening light spots, and make the skin fair and translucent.

If the two are used alone, each has its own advantages and disadvantages. What are the advantages and disadvantages of using them together? In fact, glycolic acid is acidic, and niacinamide is chemically stable at a specific pH. If the two are properly matched, not only is there no risk of conflict, but they can complement each other. Glycolic acid makes the stratum corneum of the skin thinner, and niacinamide is more permeable, enhancing the effect of whitening and repair; the soothing properties of niacinamide can relieve the irritation caused by glycol

When using it, caution is also required. Beginners should try it on a small scale first to see if the skin is uncomfortable. And the starting concentration should be low, and then adjust it as appropriate after the skin adapts. The frequency of use should not be too high to prevent the skin from being overburdened.

In short, if glycolic acid and nicotinamide are used in combination reasonably, they can bring many benefits to skin maintenance. However, users must follow the correct method according to their skin type to achieve the ideal skin care effect.
