Gentle but effective

5 stars out of a maximum of 5

This is the first vitamin C that hasn’t broken my skin out. It’s so gentle and makes your skin like glass

Amazing serum

5 stars out of a maximum of 5

Decided to give this a go after reading reviews and the price point in comparison to similar serums, and so glad I did. Has made such a difference to my skin after just a few weeks of use - so much clearer and smoother. Will definitely be a repeat buy for me.

Lightweight, comfortable and visibly improves skin! Great on its own or under makeup.

Over 8 pore clogging ingredients!

1 stars out of a maximum of 5

I was really looking forward to using this due to the reviews, however after using it I started to suffer breakouts when I am usually blemish free, I checked the ingredients and it has over 8 pore clogging ingredients, so if you cannot use pore blocking products then please avoid this. Thankfully I discontinued use and my skin improved again, disappointed due to how much it cost and it ends up actually causing you more issues.

Slightly oily serum

I haven’t broken out using this serum yet but it’s oilier than I thought oils prefer

Skincare staple

5 stars out of a maximum of 5

This is my favourite Vit C serum! Lightweight, soaks in well and doesn’t break me out like others I have tried. Also leaves skin with a gorgeous glow and smells lovely!

Great

I wasn't sure what to expect, but this serum really brightens and refreshes my 40-something skin. I will buy again!

MEDIK8 C-TETRA SERUM

3 stars out of a maximum of 5

Leaves skin feeling very hydrated but I haven’t seen any improvement on skin texture, fine lines and my pores seem emphasised after using this.

A repurchase

5 stars out of a maximum of 5

Am really enjoying my first bottle so have re bought. I have tried a few vitamin c serums and this is my favourite so far. I’m sure there are better out there but I’m tired of searching so sticking with this!

Sunshine in a bottle

5 stars out of a maximum of 5

This serum makes my skin glow like nothing else out there. I use once a day after cleansing in the morning and after a week or two, I see the difference. It’s now a staple part of my skincare routine.
