Skin looks and feels great

I've had a few small tubes of this with GWP and used them all together. It is a slightly creamier than most serums but it smooths in super easy, maybe a little too easy as I felt I had to use a little more. I sometimes had a slight tingling or stinging when applying on a particular area but no irritation and my skin is quite sensitive. It does leave the skin very smooth and kind of with more of a bounce. I'm not too keen on the smell but it wouldn't put me off using/purchasing.

Heavy and no effect

I found this serum too heavy for my oily skin as it made me greasy and I had a feeling of a film on my face after applying it. The texture of this serum is silky and silicone like and looks like a fluid. It spreads easy but seems like not to absorb fully. Haven't seen any changes with my skin tone or texture either. So it's definitely not an option for oily skin.

I’ve been buying this for years!

This is the strongest vitamin c I’ve ever used which is why I frequently re-purchase this. If you have sensitive skin maybe this product isn’t for you as it is really strong. My skin has definitely gotten brighter since using it. I just wish it wasn’t so expensive

Best Use: Treat Pigmentation / Dark Spots, Barrier Repair, Reduce Dullness, Uneven Skin Texture, Firming

I should have returned it

I didn't get round to reviewing this when I purchased it a while. In a nutshell I used it for 3 days as part of my night routine and it burnt my skin leaving it red and sore, especially around my cheekbones. I used it with midnight recovery serum which I continue to use to this day.
