Description

How it works:

Provides an indispensible weapon against skin photo-ageing and constitutes a fabulous complement to sun protection. Once applied to the skin, C-Tetra absorbs immediately and unlike creams with SPF cannot be washed off.
C-Tetra is not a substitute to sunscreens.

Adds a luminous glow to the skin, evens out skin tone and leaves it supple, bright and well hydrated.
Protects against free-radicals – high energy particles which damage collagen, the skin’s natural scaffolding.
Protects against cell wall lipid peroxidation.
Supports your sun protection regime, minimising the risk of carcinogenic changes in the skin and preventing premature skin photo-ageing.
Helps to stimulate the synthesis of collagen and elastin, causing the skin to tighten and reducing minor lines and wrinkles.
Alleviates skin inflammation and ultraviolet radiation-induced erythema – redness and skin inflammation.

Actively fights against hyperpigmentation and post-acne blemishes.
Works synergistically with White Balance.
Increases physical resistance to damage of capillary veins and thereby has a beneficial influence on redness-prone skin.

Works synergistically with Red Alert Serum.
Has an anti-inflammatory, soothing and calming effect on the skin.

Improves the lipid barrier of the skin to help protect the skin from the environmental stress, such as pollution, extreme weather conditions, UV radiation, etc.
Cost effective once daily application.
How to use:

C-Tetra has been formulated for direct application to the face. In the morning, after cleansing, apply 3-4 drops directly to the skin and blend evenly across the whole facial area, neck and décolleté. Alternatively, place a drop on your finger and massage into the skin. Leave to absorb for 2-3 minutes.

Follow with the application of Hydr8 SPF25 or your preferred SPF hydrator/sunscreen.

Note: Alternatively, if undergoing retinol regime, follow the above instructions in the evening instead. Always apply C-Tetra to the face preceding retinol application, to minimise irritation.

Key ingredients:

Tetrahexyldecyl Ascorbate (3.0%) – New lipid soluble vitamin C derivative, with FOUR times more activity than the equivalent L-Ascorbic Acid.
d-Alpha Tocopherol (natural vitamin E) (1.0%) – antioxidant, helps to protect skin from free radical damage and act as network antioxidant with vitamin C.
