The combination of nicotinamide and glycolic acid
If you want to make good use of skin care methods, you must carefully observe the properties of all products to know whether they are compatible. Today, when it comes to the combination of nicotinamide and glycolic acid, this is a common suspicion among skin care people.

Niacinamide has a peaceful sex and many benefits for the skin. It can help the skin protect its barrier, keep moisture intact, and can even out skin tone, lighten spots, and slow down skin aging. Glycolic acid is a type of fruit acid, which is active and can exfoliate, rejuvenate the skin, smooth its pores, reduce acne marks, and make the skin delicate and smooth.

However, the combination of the two must be done with caution. The pH value of nicotinamide is alkaline, and ethanol acid is an acid. If the two are rashly mixed or biochemically reacted, nicotinamide will be converted into niacin, which irritates the skin and can cause redness, itching, and tingling.

Therefore, if you want to use both, you can apply them in time. Niacinamide should be used first during the day, because it can protect the skin, protect it from external harm, and strengthen the skin's barrier. Wait until it is completely seeping into the skin, then do something else. After cleansing at night, use glycolic acid first to remove old waste keratin and promote skin renewal. After a while, the skin will be slightly calmed, and then apply nicotinamide to help the skin repair, retain water and nourish.

In addition, when using these two for the first time, it is recommended to add a small amount gradually to observe the skin's response. If the skin is sensitive, it is more necessary to be cautious, or consult a professional first, so that you can be worry-free. In this way, you can make good use of niacinamide and glycolic acid to obtain the good effects of skin care and keep the skin youthful.
