Smells divine and leaves a
Smells divine and leaves a dewy glow. I am new to vitamin C but the product is gentle enough to not irritate my skin - this is important for me as I am also using retinol. However, unfortunately the serum leaks out of the applicator when taken out of the bottle, resulting in wastage. Aside from that, the product is great!

It has a good texture, easily absorbed into the skin. It did hydrated the skin and also went well with my moisturizer and sunscreen. I used to apply a thin layer of hyaluronic acid before C-Tetra Luxe for extra hydration. I also tried the C-Tetra eye to have my eye area boosted with Vitamin C.

Fantastic product!
I’m now on my third bottle of Medik8 Vitamin C serum—and I absolutely love it! My skin has become noticeably calmer, less prone to breakouts, and the redness is significantly reduced. It’s visibly brighter, more even-toned, and feels smoother too. I wouldn’t consider switching to anything else—this has truly transformed my skincare routine!
