I’m very happy with this C-Tetra serum. It has a nice consistency and smell. I have noticed my skin is brighter and my dark spots are fading.

One of my skincare favorites
C-Tetra has quickly become one of my favorite products from Medik8. It has a lightweight, silky texture and absorbs beautifully without feeling greasy. My skin looks brighter, fresher and more radiant when I use it regularly. I also love how comfortable it feels on my dry skin and how easily it fits into my morning routine.

C-Tetra
I love Medik8 skincare, but this is not one of my favorites. It feels greasy on my face and I think it might have contributed to making my skin dry. Therefore, I will use it on my hands and arms before bed and not repurchase.
