The Eighth Edition
Clarins introduced its first Double Serum 32 years ago. This is the latest version.
The Double Serum’s defining feature has always been its oil-and-waterbased combo. Previous versions offered a ratio of 1:1, which was later found to not be ideal for skin. The ideal is one-third oil and two-thirds water, the same proportion as skin’s protective hydrolipidic film, for skin that feels more comfortable, less greasy and more balanced.
