Details

Overnight Youth Serum by Kérastase is a powerful age-corrective leave-in treatment designed to work while you sleep, reversing visible signs of hair aging by morning.

Infused with Pro-Xylane™ and Ochrophyta Algae, this advanced overnight serum delivers concentrated actives deep into the hair fiber to restore vitality, strength, and youthfulness—effortlessly, with just one pump.

Why you'll love it:

As hair ages, it can lose density, shine, and smoothness. Overnight Youth Serum targets these concerns at their source, replenishing the hair fiber during the natural nighttime renewal cycle.
Pro-Xylane™: A green-chemistry molecule renowned for its powerful anti-aging properties, helping to reinforce and densify the hair fiber
Ochrophyta Algae: A rare, bio-sourced deep-sea algae known for its regenerative and revitalizing benefits
Its ultra-light, quick-break texture melts instantly into the hair, leaving no residue—only soft, supple lengths infused with the iconic Chronologiste fragrance, transforming your nighttime routine into a luxurious ritual.

Who is it for:

Ideal for hair showing signs of aging, including:

Loss of thickness
Frizz and dryness
Dullness
Lack of volume and vitality

Perfect for anyone seeking visibly younger-looking hair by morning.
