C-Tetra® Luxe Medik8

Morning radiance ritual

Every morning, add radiance to your skin with C-Tetra® Luxe — a serum whose effectiveness in reducing wrinkles and hyperpigmentation has been confirmed by clinical studies after just 4 weeks * .

The product improves the skin's visible radiance while strengthening its protective barrier — a combination that makes daily care a real investment in the condition of the complexion.

Medik8 is a British dermocosmetic brand that organizes its entire offering around a single principle — CSA. In the morning, vitamin C and sunscreen; in the evening, vitamin A. The rest of the skincare routine complements this framework rather than being a collection of random products.

Why C-Tetra® Luxe

Thanks to twice the vitamin C content (14%) compared with the original C-Tetra serum, C-Tetra Luxe is the answer for those seeking intense skin radiance and antioxidant protection combined with deep nourishment.

This velvety-soft serum delivers visible results after just one use * , while gently caring for and nourishing the skin.

An ingredient you can rely on

At the heart of the formula is a stabilized — and therefore very potent — form of vitamin C called tetrahexyldecyl ascorbate (pronounced "tetra-hexul-dekul as-KOR-bat"). It is this stability that allows vitamin C to act effectively and remain active in the formula.

Confirmed by clinical study

The effectiveness of C-Tetra® Luxe in reducing wrinkles and hyperpigmentation, as well as the effect visible after a single application, have been confirmed in an independent clinical study of the preparation, conducted over 4 weeks on a group of 32 people.

Place in the CSA routine

In practice, this means a simple routine: in the morning, an antioxidant protects the skin from damage, a filter blocks the radiation that causes this damage, and at night vitamin A drives rebuilding. Preparations from the other categories — cleansing, moisturizing, eye area care — are chosen so that they do not conflict with this rhythm.

How to use

• 1After cleansing the skin in the morning, apply 6 drops of C-Tetra® Luxe to the face, neck, and décolletage, gently massaging until fully absorbed.
• 2Leave to absorb before applying moisturizer and sun protection.
• 3For best results, use the serum daily, incorporating it into your morning skincare routine.
• 4C-Tetra® Luxe is not only an effective brightening serum, but also powerful protection against everyday environmental stressors.
• 5With regular use, the skin becomes more radiant, firm and resistant to the ageing process, which translates into a healthy and youthful appearance.

Preparations with vitamin A are used only in the evening and introduced gradually — starting with two or three applications per week. In the morning, sunscreen is mandatory, regardless of the season.
