On the pros and cons of combining glycolic acid toner with niacinamide
The way of skin care is changing with each passing day, and new techniques and new things are emerging in an endless stream. Glycolic acid toner and niacinamide are both good skin care products, but whether the two can be mixed, many people have doubts.

Glycolic acid is a type of fruit acid, which has the power of rejuvenating the skin. It can loosen the connection between keratinocytes, make old waste keratin fall off, make the skin surface smoother, and stimulate collagen regeneration, improve skin texture, and make the skin regain its radiance. Niacinamide is also extraordinary, which can regulate sebum secretion, improve skin dullness, improve skin gloss, and enhance skin barrier and protect skin health.

However, when the two are mixed, it is necessary to be cautious. Glycolic acid is acidic, and niacinamide is not stable at a specific pH. If mixed, when the ratio of the two and the ambient pH are not suitable, niacinamide may hydrolyze into niacin. Niacin is highly irritating to the skin, or can cause allergic symptoms such as redness, tingling, and itching to the skin.

However, if properly prepared, it can also complement each other. Glycolic acid opens the skin channel, or helps niacinamide absorb better; niacinamide strengthens the skin barrier, or can relieve the irritation of glycolic acid to the skin.

Therefore, if you want to mix glycolic acid toner and nicotinamide, you should try it on a small area of skin first to see if there are any adverse reactions. And when blending, you should strictly control the ratio and follow professional guidelines in order to seek advantages and avoid disadvantages and achieve the best of skin care.
