I use many of the Biologique Recherche products and this is the second bottle of Serum de Teint that I have purchased. I have mature, dry sensitive skin and I love the light weight coverage with no irritation. It looks very natural and my skin benefits from the ingredients. I find it can pill if I try to build up the coverage so on days that I need a little more coverage I mix it with my Chantecaille Future Skin and apply with a brush for a beautiful natural look. I am fair with pink undertones and shade 1 is perfect.
