C-Tetra Advanced is an innovative next-generation anti-ageing serum featuring 20% of a highly stable form of vitamin C, designed to restore radiance, even out skin tone, and protect against daily oxidative stress.

The ultra-light, creamy texture absorbs instantly without any stickiness, leaving the skin fresh, hydrated, and supple. Powered by lipid-soluble tetrahexyldecyl ascorbate – one of the most stable forms of vitamin C – and enhanced with vitamins E and F, this potent formula neutralises free radicals, strengthens the skin barrier, and stimulates collagen production for a visibly smoother and brighter complexion.

With consistent use, the serum refines skin texture, boosts elasticity, and restores a healthy glow. After just a few applications, the skin feels firmer, more hydrated, and radiant, with a strengthened antioxidant shield that enhances long-term vitality.

Size: 30 ml

Apply 4–6 drops every morning to freshly cleansed skin. Gently massage until fully absorbed. Follow with a moisturizer and, most importantly, sunscreen (SPF).
