Vitamin C: The Most Powerful Antioxidant For A Radiant, Youthful Glow

Why Do Antioxidants Matter in Skincare?

As any “skintellectual” will know, antioxidants are key to protecting skin from premature ageing, pollution, and environmental stressors. Vitamin C remains the gold standard antioxidant in skincare, but another powerful new antioxidant making waves is acetyl zingerone.

At Medik8, we’ve taken an innovative approach to antioxidant protection with C-Tetra Advanced. Combining 20% stabilised vitamin C (tetrahexyldecyl ascorbate) with next-generation acetyl zingerone, it’s a clinically proven formula designed to visibly brighten and defend against premature skin ageing in one lightweight step.

Free Radical Damage: Explained

Every day, your skin is exposed to damaging external forces that we call environmental stressors, like pollution, UV radiation and blue light from the sun. Exposure to these stressors triggers the production of free radicals within the skin, which are reactive and unstable.

This process damages skin proteins like collagen and elastin. The result? Oxidative stress: a destructive chain reaction that leads to inflammation and visible skin ageing. As these free radical molecules are missing an electron, they ‘steal’ one from healthy skin cells to become stable.

Over time, this oxidative damage results in visible signs of ageing such as fine lines and wrinkles, sagging and loss of skin elasticity, dull and uneven skin tone, increased redness and hyperpigmentation.

What Do Antioxidants Do

Antioxidants neutralise these free radicals by donating a free electron, making them stable molecules, which protects skin from oxidative stress. Essentially halting the damage before it starts. Think of them as the skin’s natural defence shield.

When used consistently, antioxidants help to prevent the early signs of ageing to keep your skin looking smoother, firmer, and more radiant over time.

Vitamin C: Antioxidant Superhero

Vitamin C is a multifunctional skincare superhero, helping to boost collagen and brighten skin for a more youthful, radiant complexion. It is also a powerful, naturally occurring antioxidant that delivers effective protection against free radicals, boosts collagen production and helps reduce the appearance of fine lines and wrinkles. Plus, each molecule can readily donate 2 electrons, meaning it neutralises 2 free radicals, making it incredibly efficient at defending against oxidative stress.

Acetyl Zingerone: Vitamin C’s Perfect Partner

Acetyl zingerone is an omni antioxidant, meaning that it fights multiple types of free radicals, not just one. This makes it especially effective at providing full-spectrum defence against environmental damage and visible signs of skin ageing.

Acetyl zingerone is scientifically proven to enhance the stability and boost the power of vitamin C (tetrahexyldecyl ascorbate, or THDA). This means accelerated brightening results, naturally boosted collagen production, and longer-lasting antioxidant protection. Together, these two antioxidants form a perfect partnership for next-level skin protection.

C-Tetra Advanced: Brightening, Barrier Support and Age Defence

At Medik8, our latest vitamin C innovation, C-Tetra-Advanced, combines 20% THDA with acetyl zingerone in a smart, gel-serum formula. These two supercharged antioxidants work in perfect harmony, visibly improving skin brightness to revitalise dull, uneven skin tone.

With proven advanced protection against environmental damage from pollution, UVA, and blue light, experience newfound skin resilience and visibly smoother, more youthful-looking skin in one lightweight step.
