Medik8 – C - Tetra Advanced

The innovative C-Tetra Advanced serum is a highly effective product for brightening and evening out skin tone, providing daily antioxidant protection. It has been clinically proven to brighten the skin and visibly reduce wrinkles in just 7 days, without disrupting the skin barrier.

Traditional serums with a high vitamin C content can break down before reaching the skin or cause irritation. C-Tetra Advanced has been carefully formulated with a 20% stabilised vitamin C complex, providing long-lasting efficacy from the first drop to the last.

Encapsulated by nature and derived from green tea leaves, phytoexosomes are rich in proteins, lipids and messenger molecules. Acting as intelligent micro-carriers, they transport key signalling molecules, such as peptides and nutrients, to send signals to skin cells, helping to strengthen the skin barrier for optimal tolerance and skin comfort.

The next-generation formula, additionally enhanced with the comprehensive antioxidant acetyl zingerone, helps protect the skin from pollution-induced damage by neutralising free radicals, blocking harmful pollution particles and strengthening the skin’s natural defence mechanisms, increasing its resilience.

The formula, free from harsh ingredients, is suitable for all skin types, including sensitive, oily and combination skin, without causing redness or discomfort. It is also suitable for those who want to prevent signs of premature ageing and achieve naturally brighter and visibly radiant skin.

Active Ingredients:

• 20% stabilised vitamin C (tetrahexyldecyl ascorbate) – a highly effective yet gentle form of vitamin C that intensely brightens the skin and provides powerful antioxidant protection, preventing premature ageing.

• Phytoexosomes – these natural microcapsules deliver important proteins, lipids and signalling molecules directly to skin cells. Together with vitamin C, they help combat signs of ageing and support a healthy, supple appearance of the skin.

• Acetyl zingerone – a super antioxidant that works synergistically with vitamin C, enhancing its action.

• Hyaluronic acid of different molecular weights – attracts moisture into the skin, instantly smooths it, deeply hydrates it and makes it soft and supple.

• 2% N-acetylglucosamine (NAG) – this gentle ingredient supports the skin’s protective barrier, evens out texture, reduces pores and stimulates the production of the skin’s own hyaluronic acid.
