Using [glycolic acid](https://lovi.care/skincare/fr/ingredients/glycolic-acid) and [niacinamide](https://lovi.care/skincare/fr/ingredients/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. ## Research on glycolic acid and niacinamide - [The effect of niacinamide on reducing cutaneous pigmentation and suppression of melanosome transfer](https://pubmed.ncbi.nlm.nih.gov/12100180/) Niacinamide · The British Journal of Dermatology, 2002 -
