The Y Theorem Repair Light Serum NAC Y²™ is a feather-light daily serum designed to rejuvenate and strengthen skin, especially ideal for combination, oily, or sensitive types. Born from surgical innovation, this version harnesses the power of the proprietary NAC Y²™ complex—featuring vitamin C, escin, and N-acetyl cysteine—to promote glutathione production, boost collagen and elastin, and improve skin elasticity. Enhanced with niacinamide, liquorice root, calendula, and centella asiatica, it calms redness, brightens tone, and hydrates without weighing the skin down. Clinically formulated to support recovery from environmental stress and post-procedure sensitivity, it delivers visible texture improvement, glow, and resilience—without clogging pores—earning high praise and awards like the Wardrobe Icons Best Serum 2023. Product Features - Enhances repair and resilience by supporting collagen, elastin, and hyaluronic acid production Soothes and balances redness while refining texture and brightening skin tone Ultra-lightweight, non-comedogenic formula perfect for oily, humid, or sensitive conditions How to Use - After cleansing (and optional essence), dispense 1–2 pump(s) between fingertips. Gently apply to face and neck in upward motions, morning and evening before moisturizer. Follow with your favorite moisturizer and SPF in the morning. Consistent use supports smoother texture, durability, and a refreshed appearance—especially in challenging environments or post-treatment skin.
