One product I keep coming back to
Honestly I don’t know why I even bother with trying other oils as this is great for my highly sensitive allergy prone and cyst prone combination skin. It keeps me hydrated and glowing in a healthy way and it works great with basically any moisturizer on top!

Radiant Mornings – My Experience with Medik8 C-Tetra Serum
The serum has a lightweight, oil-based texture that absorbs quickly without feeling greasy. It has a subtle citrus scent that feels fresh and natural – not overpowering at all. My skin looked noticeably more radiant within a week. It gives that “glow from within” look without irritation or stickiness. It layers well under moisturizer and sunscreen, making it perfect for morning routines. It contains tetrahexyldecyl ascorbate, a stable and non-irritating form of vitamin C, along with vitamin E. This combination boosts brightness, defends against environmental stress, and supports collagen production.

Great product
Glad i have discovered Medik8 a few years back as i really like all their products i used so far. Vitamin C is one of them. I use it in the morning on clean skin. Not sticky, smells nice, absorbs easily and leaves my skin glowing and healthy.
