Vitamins C and E provide antioxidant protection.

Together, the formula's active ingredients help combat sun and pollution damage.

The lightweight yet powerful formula stimulates collagen and elastin production to visibly smooth fine lines and wrinkles, and brighten and even out skin tone.

Using a fat-soluble form of vitamin C, tetrahexyl ascorbate, the formula penetrates deep into the skin to provide maximum antioxidant protection with minimal irritation.

C-Tetra Serum has been carefully formulated to be water-free, which guarantees 100% stability and preservation of the full potential of vitamin C throughout the shelf life.

The formula contains nourishing oils combined with the anti-aging power of vitamin C. The serum is quickly absorbed and is ideal for those who want to rejuvenate their skin. It is the best choice for those who are new to vitamin C, as well as for those who want to take it up a notch after using C-Tetra Cream or Daily Radiance Vitamin C.

HOW IT WORKS
Our skin is filled with natural antioxidants that protect us from free radical attack from the environment. But if the number of radicals exceeds the number of antioxidants, the skin is no longer able to defend itself.

Free radicals attack defenseless skin cells, causing irreparable damage that ultimately leads to premature skin aging.

C-Tetra Serum contains tetrahexyl decyl ascorbate, a super-stable form of vitamin C that boosts the skin's antioxidant defense. Moreover, the multitasking tetrahexyl ascorbate stimulates collagen production, which helps to smooth wrinkles, improve skin tone and tone, and promote a healthy glow.

As a lipid-soluble form of vitamin C, it can easily penetrate the skin's protective lipid barrier to act deeper where it is needed most. Vitamins C and E synergistically create an “antioxidant network”, enhancing the overall antioxidant potential of the cream for optimal skin protection throughout the day.

The brightening effect of the serum is enhanced by passion fruit oil, which is rich in vitamin E and nourishing fatty acids. The intensive version of our iconic serum is now infused with nourishing vitamin F and squalane, which help restore the skin's natural protective barrier to fight off free radicals. What's more, optimized red ginseng extract enhances the serum's brightening and whitening effects to reveal an even, radiant complexion.
