C-Tetra Advanced by Medik8.

Your New Gold Standard in Vitamin C Skincare

If you're serious about defending your skin from premature ageing and chasing that radiant, healthy glow, let us introduce you to your new daily essential: Medik8 C-Tetra Advanced. This isn't just another vitamin C serum, it’s a high-performance, clinically backed formula that works smarter, not harsher.

At its core, this serum delivers a potent 20% stabilised vitamin C (Tetrahexyldecyl Ascorbate). That means deep skin penetration, impressive stability, and serious brightening power, all without the sting or irritation. It’s been clinically proven to visibly brighten skin and improve fine lines and wrinkles in just 7 days, with zero barrier disruption. Yes, really. Glowing, smoother skin in a week? We’ll take that.

But what really sets Medik8 C-Tetra Advanced apart is the way it multitasks. It’s not just about brightness, it’s about long-term skin health and defence. The formula is fortified with cutting-edge phyto exosomes, which act like little recovery messengers, helping your skin bounce back from environmental stressors like pollution, UV rays, and blue light.

Add in acetyl zingerone, a next-gen antioxidant that neutralises free radicals from all angles, and you’ve got serious armour against premature ageing.

Now for the hydration heroes; multi-weight hyaluronic acid dives into different layers of the skin to keep it plump, juicy, and moisturised all day. And N-acetyl glucosamine (NAG)? It's a skin-smoothing, tone-evening wonder that also supports your skin barrier.

Why love Medik8 C-Tetra Advanced:

  • 20% Stabilised Vitamin C (Tetrahexyldecyl Ascorbate) – Brightens, firms, and protects.
  • Phyto Exosomes – Boost skin recovery and defence.
  • Acetyl Zingerone – Ultra-powerful antioxidant protection.
  • Multi-Weight Hyaluronic Acid – Deep, lasting hydration.
  • N-Acetyl Glucosamine (NAG) – Refines texture, evens tone, and supports barrier health.

Medik8 C-Tetra Advanced is your glow-getting, wrinkle-fighting, skin-loving serum. High performance, and zero compromise, just the way we like it.
