Why shouldn’t nicotinamide be used in skincare with acidic ingredients?

Nicotinamide, also known as vitamin B3, is a water-soluble vitamin. Nicotinamide works synergically with natural substances in the skin to effectively shrink pores, improve uneven skin tone, lighten fine lines and wrinkles, reduce skin darkness, and strengthen fragility.

Nicotinamide reduces environmental damage to the skin, mainly because it strengthens the skin barrier (the first line of defense) and also improves damaged skin. If we don’t control this damage in our daily lives, our skin will become older, darker, and less shiny over time.

Nicotinamide can be found in some skin care products in our daily life, such as toner, serums and so on. Nicotinamide has unique compatibility with most skin care products, including those containing retinol, peptides, hyaluronic acid, AHAs, BHA, vitamin C, and antioxidant types. However, it is not recommended to be used with acidic skin care products, which can increase skin irritation.
