Chronologiste Overnight Youth Serum is a luxurious new overnight treatment that combines science-driven haircare with a sensorial beauty ritual. Inspired by the skin’s natural overnight renewal cycle, this serum works throughout the night to help restore the hair fiber’s elasticity, smoothness and radiance while Your body is in its natural regenerative state. Its innovative formula contains moisturizing and anti-dryness polymers that penetrate deep into the hair fiber, helping to correct and protect the hair structure from within. At the same time, glycerin helps lock in moisture, improving hair elasticity, smoothness and natural shine.
The result is hair that looks healthier, stronger and more Youthful by the next morning. The serum’s lightweight, luxurious gel texture absorbs quickly into the hair, leaving it silky soft and easy to manage without weighing it down or leaving residue. It transforms Your evening haircare routine into a calming and indulgent ritual.
