Kérastase has introduced the Chronologiste Overnight Youth Serum, a night treatment formulated to address the visible effects of aging on hair by applying principles commonly associated with advanced skincare.
Kérastase's Chronologiste Overnight Youth Serum targets five specific concerns — dryness, dullness, reduced volume, thinning, and frizz — through a blend of Pro-Xylane and Ochrophyta Algae. These powerful ingredients work to strengthen and restore hair while the body rests.
The Chronologiste Overnight Youth Serum is designed for simple integration into a nighttime routine. The formulation is applied to dry or damp hair before sleep and left to work until morning. Individuals can expect to wake up with silky and luminous strands and the sensory appeal of the brand's signature Chronologiste fragrance.
