Chronologiste Overnight Youth Serum 90ml

Wake up to hair that looks visibly healthier, softer, and more youthful with Kérastase Chronologiste Overnight Youth Serum. This luxurious leave-in night treatment works while you sleep to help reverse the visible signs of ageing, targeting dryness, dullness, frizz, loss of volume, and thinning hair.

Powered by Pro-Xylane™, renowned for its age-defying properties, and Ochrophyta Algae, a precious deep-sea ingredient celebrated for its regenerative benefits, the formula delivers concentrated active ingredients deep into the hair fibre with just one pump.

Its innovative, lightweight texture melts instantly into the lengths without weighing hair down, providing intensive overnight nourishment and leaving hair feeling smoother, fuller, and beautifully revitalised by morning.

Finished with the iconic Chronologiste fragrance, this indulgent serum transforms your evening haircare routine into a truly luxurious ritual, revealing hair that looks renewed, radiant, and full of life.
