Ultimate A, Intensive Vitamin A Serum 30ml
Revolutionising Vitamin A Skincare
Ultimate A is a high-performance anti-aging serum powered by Iconic A®, our patented, stabilised Retinaldehyde—the closest non-prescription form to pharmaceutical-grade Retinoic Acid. This advanced formulation is designed to transform skin health by stimulating collagen, refining clarity, and reducing visible signs of aging while remaining gentle enough for daily use.

- Brightens & Clarifies – Improves radiance, tone, and skin texture for a renewed, youthful glow.
- Powerful Antioxidant Defense – Fortified with Resveratrol and Thiotaine, protecting against UV damage and oxidative stress.
-
Chiral Correct Precision – Employs cutting-edge chirally correct technology, allowing medical-strength active ingredients to penetrate the skin with unparalleled precision while minimising irritation.
