Y Theorem Repair Light Serum NAC Y2 is a featherlight serum that strengthens and revitalizes skin, ideal for combination, oily, and sensitive skin types. Developed by Dr. Yannis Alexandrides, this innovative formula harnesses the power of the proprietary NAC Y²™ complex—featuring vitamin C, escin, and N‑acetyl cysteine to enhance glutathione production, along with niacinamide, liquorice root, calendula, and centella asiatica—to soothe redness, improve clarity, and boost skin elasticity without heaviness. Clinically proven results show a visible reduction in fine lines and boosted skin resilience, all wrapped in a non‑comedogenic, breathable texture praised by skincare experts as a post-surgical-grade rescue for stressed or environment-worn skin.
