Ascorbic Acid 8% + Alpha Arbutin 2%

Bonjour j'ai lu que c'est une mauvaise idee de combiner en meme temps le niacinamide et la vitamin C. Serait ce possible d'utiliser un le matin et l'autre le soir et ne Pas annuler Les effets des produits? Merci

I wouldn't recommend this as a first vitamin C serum for someone with sensitive skin. I bought it because I was encouraged by good opinions but it was too much for my skin, which became very irritated. Start with a gentler vitamin c serum and build up your resistance first, and then give it a try!
