Best c vitamin

5 stars out of a maximum of 5

I love it, it’s hydrating and feels good on the skin, such a staple in my morning routine. It doesn’t sting or irritates my skin as some c vitamins can do

Light weight and perfect for combination skin

5 stars out of a maximum of 5

The serum is very lightweight compared to the luxe. It’s definitely early days but I love the feel of it already paired with my Medik8 Crystal Retinal

So far, so good

4 stars out of a maximum of 5

I’m a big fan of many products from this brand, especially the crystal retinal that gives noticeable results. I could never get on with Medik8’s tetra-C serum but this new lighter gel formula is very pleasant on my combo skin. I know with these products you can only see results over time and with regular use. It’s early days on this one but hoping it lives up to the hype!

Lovely

5 stars out of a maximum of 5

This is the best vitamin c ever! I’ve used a lot but I will stick to this now. Goes lovely with other serums and lovely under makeup. Skin looks so glowy

Gives results

3 stars out of a maximum of 5

Serum is a lightweight texture that doesn’t pill. Brightens overall complexion but has little effects on dark spots.

Medik8 C-Tetra Advanced

5 stars out of a maximum of 5

I was never a fan of Medik8 dry oil vitamin C serums, I much prefer this serum. It’s very pleasant to use and is not at all irritating.

I like it so far

4 stars out of a maximum of 5

I am still in my first bottle of this but I like it so far. It does not irritate my skin and applies smoothly under make up. I can’t say I have seen any visible improvement to my skin from this product alone though as I use a few other products.

Amazing

5 stars out of a maximum of 5

I've struggled so much with vitamin C products over the past few years. They've always irritated me and destroyed my skin barrier. This product, however, is so different! Zero irritation! Leaves my skin so glowy and gorgeous, I really can't believe it.

Lovely vitamin c

4 stars out of a maximum of 5

I really like medik8 as a brand and this is a lovely serum. I think it’s adds a glow and a difference to my skin however I do think I will revert back to the original as I like the more oil feel
