3% Stabilised Vitamin C (tetrahexyldecyl ascorbate)
A low-irritation form of vitamin C that delivers exceptional antioxidant protection against harmful free radical damage while supporting collagen production for a visibly even, more youthful-looking complexion.
Vitamin E
A powerful antioxidant that provides additional antioxidant protection against the ageing effects of free radicals. It also helps to boost the power of vitamin C for optimum visible results.
After cleansing in the morning, apply a small amount across the brow bone and under-eye area - avoiding the eyelids.
How do I use C-Tetra Eye?
Apply 2-3 drops to clean, dry skin before moisturiser. Gently press into the face and neck, allowing full absorption before layering other products.
Why is vitamin C important in skincare?
Vitamin C is a potent antioxidant that neutralises free radical damage from UV exposure and pollution. It brightens skin tone, fades dark spots, and supports collagen production. For best results, use in the morning under SPF — they work synergistically to protect your skin.
What should I avoid mixing with vitamin C?
Vitamin C works best applied alone in the morning before SPF. Avoid layering with retinol or strong acids in the same routine — use them at different times of day. Niacinamide, hyaluronic acid, and SPF are excellent companions for vitamin C.
At what age should I start using anti-ageing products?
Prevention is easier than correction. Most dermatologists recommend starting a basic anti-ageing routine (antioxidants, SPF, and a gentle retinol) in your mid-to-late twenties. However, it is never too late to start — the skin responds to active ingredients at any age.
