Love it!
I think I have used few bottles of it already. I have combination skin. Sensitive. And this oil feels very good on my skin. Worth trying for sure.

Adore this stuff!
I first tried Medik8 C-Tetra Luxe as part of a free trial for their CSA range and even though there was only enough of it for about 3 days I was hooked and knew I’d invest in a full sized bottle. It’s soooo nice on my skin, a really luxurious sensation and the serum soaks in well without feeling greasy but leaves my face feeling like it’s had some TLC. Waited til it was on offer to buy as it’s pricey but such a treat!
