The formula is very good; feels more powerful than C-Tetra. But the smell really puts me off and the consistency is thicker so I feel it's more difficult to spread over the face unless I use more drops. I prefer C-Tetra over this.

Amazing serum, not too harsh on my sensitive skin, lovely texture that skinks in nicely and gives my skin a lovely glow. I would say its just as good as the skinceuticals but not quite as expensive

This vit C is unreal! leaves skin really hydrated and smells lovely! Can't live without it!

I’ve tried many vitamin c serums and this is the last one I’ll try for the foreseeable future. A pleasure to apply, feels hydrating and plumping, and leaves the skin feeling amazing.

I really enjoy applying this product because of its lightweight texture and there is an amazing solution — you can control the quantity used as there are signs: 0.1 ml, 0.2 ml and so on at the pipette.  I like that it contains ferulic acid which along with vitamin C is said to boost collagen production in my skin.
