Glycolic acid and niacinamide: depends on the strength

Depends on the strength

Use them at different times of day with niacinamide in the morning and glycolic acid at night, because strong acids can clash with niacinamide. Mixing them can cause temporary redness and stinging on your skin. You can switch to a gentler product strength or wait at least thirty minutes between applying them.

Questions and answers

Can you use glycolic acid and niacinamide together?

Using glycolic acid and niacinamide together depends on the strength because strong acids can convert niacinamide and cause flushing and irritation. You can safely use them by separating the ingredients by at least 30 minutes or using them in different routines such as morning and night.

Which goes first, glycolic acid or niacinamide?

Glycolic acid and niacinamide should be separated by at least thirty minutes or used in different routines because strong acids can cause flushing and irritation when combined with niacinamide. Products like Rodial SUPER ACIDS X-TREME HANGOVER MASK and COSRX AHA 7 Whitehead Power Liquid contain both ingredients, so using them at different times of day helps prevent overloading sensitive skin.

Are glycolic acid and niacinamide good for sensitive skin?

Glycolic acid and niacinamide may not be suitable for sensitive skin depending on the strength, because strong glycolic acid can convert niacinamide and cause flushing and irritation. To avoid this, you can separate them by at least 30 minutes or use them in different routines such as AM and PM. Products like Rodial SUPER ACIDS X-TREME HANGOVER MASK and COSRX AHA 7 Whitehead Power Liquid contain both ingredients.
