Isntree Hyper Niacinamide 20 Serum 20ml

Isntree Hyper Niacinamide 20 is a 20ml serum built around niacinamide at 20%, one of the higher concentrations available in a niacinamide serum, with arbutin and zinc PCA backing it up further down the list. Several forms of hyaluronic acid sit in the base for hydration, and plant extracts including evening primrose flower and kudzu root round out the formula. Because of the strength, some people notice mild flushing or tingling as skin adjusts.
