Akua Vitamin C 10% Face Serum

Key Ingredients

• Ethyl Ascorbic Acid (Vitamin C Derivative)
• Centella Asiatica (CICA)
• Hyaluronic Acid

How These Ingredients Work Together

Ethyl Ascorbic Acid brightens and improves skin texture by stimulating collagen production and fighting oxidative damage. The addition of Centella Asiatica ensures that the serum not only brightens but also heals and calms sensitive/inflamed skin. Meanwhile, Hyaluronic Acid ensures the skin stays hydrated and plump, addressing any dryness that might arise from the active ingredients.
