Beautiful
This is one up on the Medik8 C-Tetra, which I used for years. This is more nourishing whilst still deliving a signature glow 🌟

Holy Grail
This is my second bottle of this and third in the Medik8 Vitamin C range. It gives your skin the most lovely glow and sinks in perfectly after a couple of minutes. My skin is no longer dull and it's improved my hyper-pigmentation. The price is eye-watering to the point where I've started researching for cheaper alternatives but my LF rewards points saved the day! Thankfully the product lasts ages so I'll have plenty of time to build up my points for next time.

Vitamin C
Fabulous product, I use this every morning, my skin feels brighter and more even skin tone. I love it. So many people comment on how well I look and I think its down to the Vitamin C and Retinal 6 from Medik8.

Good
I use this serum every morning before my SPF and make up. It's a nice smelling oil that doesn't take too long to absorb. Crucially for me, it doesn't cause any pilling or problems for my make up. It gives a nice dewy appearance under make up.

Repeat purchase
This is a repeat purchase which I have bought multiple times. Much prefer the feeling of this vitamin C to most that feel dry. This one is not dry at all and I have noticed a difference in my pigmentation since using it.
