Medik8 C Tetra Cream is a daytime moisturiser that hydrates and restores radiance.

This silky cream provides antioxidant protection at the same times as it nourishes the skin, giving it the hydration it needs to function correctly.

It enhances the complexion utilising the same C technology found in Medik8’s best-selling C Tetra serum.

Why Medik8 C Tetra Cream?

Medik8 C Tetra Cream has been developed as a day cream. It uses a new form of Vitamin C that’s totally stable and doesn’t oxidise. This prevents it from becoming pro-oxidant and potentially causing damage to the skin.

Called Tetrahexyldecyl Ascorbate, this Vitamin C is lipid soluble, which allows it to penetrate deeper into the skin to deliver its benefits. Unlike L’Ascorbic Acid, Tetrahexydecyl Ascorbate causes little to no irritation.

This Vitamin C cream shields the skin against the damaging effects of environmental stressors, such as UV radiation, pollution and chemicals. It works to neutralise free radicals and counter the premature ageing they cause to the skin.

Medik8 C Tetra Cream blankets the skin in moisture and gradually restores a brighter complexion.

This multi-tasking cream doubles up as a serum and day cream. The antioxidants in this formulation help reduce the appearance of fine lines and wrinkles, while the moisture magnets deeply hydrate the skin.

Being lipid-soluble, the Vitamin C and Vitamin E used are able to penetrate the skin and work synergistically together to enhance their protective effects.

It will enhance your complexion and leave the skin feeling dewy and supple.

Key ingredients

Tetrahexyldecyl Ascorbate is a new generation Vitamin C that provides exceptional antioxidant protection from harmful free radicals. Being lipid soluble, it’s better able to penetrate the skin barrier. Tetrahexyldecyl Ascorbate has been shown to stimulate collagen and inhibit the production of pigment, thereby promoting skin that looks less wrinkled and more even toned. Research on this form of Vitamin C is more limited, however a study showed Tetrahexyldecyl Ascorbate to increase collagen at more than twice the rate of L’Ascorbic Acid.

Vitamin E is an exceptional companion to Vitamin C. This antioxidant is also lipid soluble. Found naturally in the skin, it works as an antioxidant in its own right, but it also plays a special role in regenerating Vitamin C to keep it active for longer.

Hyaluronic Acid has the amazing power of being able attract and hold 1000 times its own weight in water. It draws moisture from the surrounding atmosphere  into the skin and leaves the skin feeling hydrated, supple and plump.

Glycerin is one of skin care’s hardest working ingredients and a moisture magnet. Like Hyaluronic Acid, it draws water into the skin and holds it there. It replenishes the skin’s all-important own Natural Moisturising Factors and strengthens the moisture barrier. It also protects the skin against external sources of irritation and leaves the skin feeling comfortable, soft and supple.

Medik8 C Tetra Cream Review

I love this moisturiser. It feels so lovely and light and fresh on my face, yet so hydrating. I’ve tried others but always come back to this one. I have normal combination skin and this cream feels so nourishing and hydrating on my skin yet it’s lightweight and doesn’t leave an oily or shiny finish. Love this product and won’t use anything else.

After cleansing in the morning, apply a small amount of Medik8 C tetra Cream to the face, neck and decollétage. Massage in gently to aid absorption.

Follow with a broad-spectrum sunscreen.
