Kérastase Chronologiste Youth Revitalizing Night Serum – Anti-aging leave-in night treatment

Kérastase Chronologiste Sérum Nuit Jeunesse: the restorative treatment that works while you sleep

The Kérastase Chronologiste Sérum Nuit Jeunesse is a premium hair treatment designed to act overnight to correct the visible signs of hair aging. During sleep, the hair fiber regenerates and absorbs nourishing active ingredients to restore softness, suppleness, and radiance.

This nighttime serum targets several issues related to hair aging: dry hair, loss of shine, frizz, lack of density, and weakened fibers. Its lightweight texture penetrates quickly without weighing hair down or leaving residue.

Upon waking, hair appears softer, stronger, shinier, and visibly revitalized.

This nighttime treatment is also appreciated for its signature Chronologiste scent, an elegant and refined fragrance that turns application into a true beauty ritual.
