Absorbent with great resutls

5 stars out of a maximum of 5

As soon as this came out I had to buy due to its potency and Medik8 always seem to come out on top for their VitC serums. Despite it being more of a cream rather than serum this absorbs into the skin really quickly and feels like a luxury product. I’ve only been using for a couple of weeks but already see a difference. My skin looks much brighter!

Love

5 stars out of a maximum of 5

Really like this vitamin c doesn’t irritate me and is better for mature skins, over 40. Better then the oil versions

Absolutely worth every penny

5 stars out of a maximum of 5

Medik8 has smashed it again. I’ve not found a vitamin C serum that didn’t aggravate my skin and rosacea. Until now. It is super brightening and done my skin the world of good. I would recommend to everyone I know!

Very gentle

I have been using this for over a week now and have not broken out. So far it seems to be gentle yet effective.

So Brightening!

5 stars out of a maximum of 5

So fab to find a 20% Vitamin C that works for my skin. I’m so cautious with skincare but Medik8 never fails to deliver with skin barrier protection. I’d definitely recommend pairing with sunscreen in the morning and retinal in the evening for the smoothest complexion.

my new fave vitamin C!!

5 stars out of a maximum of 5

I've really enjoyed using this Vitamin C! The gel texture is super light and silky, so it absorbs quickly without leaving any sticky or greasy feeling. It feels really nice on the skin - it just melts right in. Since I started using it, my skin looks brighter and smoother with a healthy glow. Would definitely recommend!

Amazing Results

5 stars out of a maximum of 5

This is by far one of the best Vitamin C's I have used - I serum texture is beautiful; absorbs really well and sits perfectly under other creams and make up with no pilling. It has a mild orange-y smell but I find this really pleasant as it's not overpowering at all. I've been using it for 2 weeks now and my skin is visibly brighter, more even and my pigmentation reduced. Another incredible product from Medik8 that I would recommend and definitely repurchase.

Medik8 just never fail to impress!!

5 stars out of a maximum of 5

Yet again, another outstanding serum from a brand at the forefront of innovation! I am the biggest fan of C-Tetra Luxe so I couldn't wait to get my hands on the new launch! It's very different in terms of texture as it's more gel/cream-based but the radiance it produces on the skin is incredible! I am a big lover of Vitamin C and knowing that this is Medik8's strongest has got me so excited for even more brightened and radiant skin!

Highly recommended

5 stars out of a maximum of 5

Amazed at the results that pretty much were within a week of using this. I’ve struggled to find a vitamin C that My skin doesn’t react with. This is amazing, no reaction and started working within a week! This will be a repeat purchase.

Brilliant vitamin c

5 stars out of a maximum of 5

Love medik8 as a brand as the products are worth the price. Powerful vitamin c but not irritating to skin at all and gives an instant glow. Works well alongside my other skincare.
