The newest addition to the Chronologiste Hair Care Collection Kérastase Sérum Universel is an essential, revitalizing scalp and hair serum with Hyaluronic Acid, Vitamin E and Abyssine. Inspired by Caviar and its revitalizing properties, Sérum Universel uses revolutionary biometric caviar encapsulation technology to protect and preserve ultra-powerful regenerative active ingredients at their purest potency before releasing them in a silky, white serum.

After extensive formula testing from the most advanced skincare, Sérum Universel is Kérastase’s 1st youth revitalising serum for scalp and hair. Formulated with a trifecta of powerful active ingredients, Serum Universel Hyaluronic Acid serum intensely plumps and hydrates, shields against degeneration and regenerates hair fibre vitality for healthy, plumped hair that looks untouched by time.

Kérastase recommends applying Sérum Universel anti-ageing hair serum after washing your hair with a pre-shampoo, shampoo, conditioner & hair mask. Gently massage 1 or 2 pumps on damp or dry scalp and hair then apply through lengths to ends. Leave-in. Can be used multiple times per week. For best results, follow with the Chronologiste Thermique Régénérant blow dry spray.

This special patented packaging was designed for Kérastase with advanced biometric caviar encapsulation technology and a luxurious design to deliver the purest actives.
  Biomimetic caviar pearls are individually pulled into the applicator. Once they reach the top, the black membrane of each pearl is broken to release the active ingredients at their purest potency. The pump then releases a silky white essence of active ingredients. The expended pearls are then stored inside the bottle's inner chamber.
