The comparison between niacinamide and glycolic acid
There are two skin care products in the world, one is niacinamide and the other is glycolic acid. The two have their own advantages and disadvantages in the skin.

Niacinamide is mild in nature and suitable for many skin types. It can solidify the skin barrier, make the skin tough, and is like building a city to protect against external evil. And it can prevent melanin from moving to the epidermis, making the skin gradually whiter, with a smooth and shiny color. It can also adjust the skin's fat, balance oil and water, and keep the face free of oily light. Dry people must also be nourished.

Glycolic acid is one of the fruit acids, with small molecules, which can quickly enter the deep layers of the skin. It is good at exfoliating, such as removing the old and adding new ones, making the stratum corneum of the skin even and thin, and the skin surface smooth. It can promote the metabolism of the skin, rejuvenate the skin, and make the skin look youthful again. However, its sex is slightly stronger, those with sensitive skin may not tolerate it, and those who use it for the first time may have itching and redness.

Use nicotinamide, which can moisturize the skin for a long time, gradually change its quality, and is suitable for those with stable and gradual changes in the skin. Using glycolic acid can quickly change the skin's surface condition, and the rejuvenation is significant. However, it needs to be reviewed for skin tolerance and used with caution. Compared with the two, there is no absolute advantage or disadvantage, but it depends on the nature of the individual skin and the requirements. If you make good use of it, you can rejuvenate your skin.
