Featuring C-Tetra®, Advanced Day Total Protect™ (with Sunscreen) and Retinol 3TR Intense™. It has everything you need for a healthy, glowing complexion. The Set Contains: C-Tetra (10ml) Restore radiance and fight visible signs of ageing with C-Tetra®, a super-light daily vitamin C serum. Antioxidant power is provided through vitamin C and E. Together, these actives help to combat sun and pollution-induced damage. The lightweight, uplifting formula helps reduce fine lines and wrinkles, as well as visibly brightening the complexion and balancing skin tone. Using a lipid-soluble form of vitamin C called tetrahexyldecyl ascorbate, the formula penetrates deep into skin to provide powerful antioxidant protection with minimal irritation. C-Tetra® has been carefully crafted in a water-free formula to be 100% stable, which means that the vitamin C does not degrade over time. This ensures that your formula remains highly potent from the very first use to the final drop. Advanced Day Total Protect (15ml) Our most advanced day cream ever.

Effectively protecting skin from free-radical damage, this is the ultimate daily hydrator for total environmental protection. The advanced moisturiser is super-light and has an invisible finish, making it the perfect daily cream. Fine lines and wrinkles are visibly reduced and future skin ageing is prevented. Retinol 3TR Intense (5ml) Take your evening skincare to the next level with Retinol 3TR+ Intense. A lightweight vitamin A night serum that refines skin tone and texture to visibly diminish fine lines and wrinkles while you sleep. As the most effective ingredient in anti-ageing, vitamin A also balances uneven skin tone and helps to decongest pores for a clearer complexion. Crafted with Time Release Technology, the innovative serum allows retinol to be “drip-fed” into the skin throughout the night, preventing unwanted irritation and dryness. Retinol 3TR+ Intense has been supercharged with climbazole, a compound proven to boost the results and anti-ageing benefits of vitamin A without increasing the irritation.* The formula is also infused with squalane, a deeply hydrating ingredient; specially selected to ensure skin is left instantly plumped and smoothed.
