My Holy Grail Vitamin C
I love this product! It is an oil based serum so if that's not your thing this won't be for you. My normal to dry skin absolutely loves this product. I use every other morning after cleansing. Just a couple of drops is enough to do my whole face. Despite being an oil this doesn't leave my skin greasy or oily after application, it just gives my skin a gorgeous glow. It sinks in quickly and I can apply my moisturiser and make up on top easily. Sometimes I deviate away from this as I get swayed by other products easily - however I ALWAYS end up coming back to it. I have used up multiple bottles of this now which shows how much I enjoy it. Although the bottle is small I find it lasts me a good amount of time before I need to replace. Definitely my Holy Grail Vitamin C product ❤️

Gold Standard of Vitamin C Serums
Medik8 is well known for its vitamin C formulas. I return to this brand again and again, despite the spendy price tag. Use it in the morning before your moisturiser and see the results!
