Rated 5 out of 5 by from A product that makes a difference After using C-Tetra in the morning, and crystal retinal 3 at night i had spotty breakouts. I reached out to Medik8 for support which meant perseverance for a few months. The C-Tetra ran out so I decided to take a chance on C-Tetra Luxe and believe this has made a significance difference to my skin.

Rated 5 out of 5 by from Amazing vitamin C serum! C-Tetra from Medik8 is the first product I've tried, and I absolutely love it! After struggling to find the right vitamin C serum, I finally found one that works for my combination skin. Despite being oil-based, it feels lightweight and absorbs quickly, leaving my skin smooth and radiant. I also appreciate its 12-month stability after opening, compared to the 3 to 6 months of others. I'm excited to explore more Medik8 products and highly recommend C-Tetra!

Rated 5 out of 5 by from Glowing skin I’ve been using this every morning and my skin absolutely glows after application! I have used many vitamin C serums, which I’ve found aggravating on my sensitive skin. This is gently but effective and absolutely works! Love it.

Rated 5 out of 5 by from Natural glow serum Medik8 C-Tetra® Luxe is a lovely serum to use before moisturiser. It has a delightful scent, glides smoothly onto the skin, and isn't sticky at all. After application, it leaves a beautiful glow, allowing me to confidently go out with just this and a moisturiser, without needing any foundation. Highly recommend it!
