Vit C
Will always repurchase this! It makes my skin glow!

Light, easily absorbed, noticed a massive difference to skin tone
All you hear about these days is how important Vitamin C and retinoids are for anti-ageing. After doing my research, I found that not all vit c serums are created equally. If you want to use vit c in your routine but you are worried about the cost - buy this and save money on a moisturiser or skip the toner. This serum is light and has a beautiful light citrus fragrance. It applies beautifully, sinks in after a minute or so without leaving any greasiness. I highly recommend this serum. It is expensive, so wait until it’s on offer. It’s a false economy to buy cheap vit c because it will not work as well as this. I have almost finished my first bottle and the difference it has made to my skin tone is already noticeable. Highly recommend.

Nice Serum
Serum feels a bit oily at first so I thought it might leave a greasy feeling on the skin but it absorbed quickly and sat well under makeup. Nice smell a bit like oranges. I haven't seen much difference in skin since using it but I will keep using for a while as Medik8 products are normally very good. Reasonably priced and well packaged

Love it!
I have very sensitive skin so I was a bit weary, starting with vitamin C. I saw it was a great vitamin C serum for beginners and sensitive skin, so I bit the bullet and bought it. It's done wonders for my complexion; my skin is more even, and the redness has reduced significantly. I will definitely be repurchasing :)

Miracle bottle
Love love love this product. My skin glows and it’s made a massive difference to my pigmentation. You only need a few drops and it goes a long way. My skin does not look shiny and feel oily after the product has soaked in. Always apply with the medik8 spf50 day cream and my skin has never looked better! Make sure you don’t apply more than you need, sometimes vitamin C can cause breakouts initially or if too much product is applied. Highly Reccomended.
