Gentle yet effective

5 stars out of a maximum of 5

I am indeed someone who is sensitive to vitamin c products, whether that's because of the formula or ingredients used, but I have found out I am left irritated or worse, with an allergic reaction. I was reluctant to try this, but I made sure I patch tested, not to mention I just couldn't resist, as the texture of this serum is so unique. It's been about 10 days since using this in the morning, and my skin is already clearer, brighter and overall much smoother and even better - no signs of a reaction! Would recommend and very likely to repurchase.

A new staple in my morning routine

5 stars out of a maximum of 5

I've been using this vit C serum every morning for a week, and I can definitely see that my skin looks noticeably brighter and smoother. The texture is lightweight and hydrating making it the perfect base for my moisturiser, SPF, and then makeup. Can't wait to see the longer term results!

OBSESSED

5 stars out of a maximum of 5

I am obsessed with this vitamin C! I've been using this for about a week now and am so impressed with the results. My skin is brighter, plumper and I've already noticed a reduction in the redness on my face. The texture is sooo lovely and creamy and absorbs into your skin so nicely. Would highly recommend for vitamin C pros and newbies alike! It's a really lovely formula and a great alternative if you're not so keen on oils!

So Far I'm Loving

5 stars out of a maximum of 5

I have used it consistently for a week and have really noticed a difference in the brightness of my skin. I love the creamy texture, non-greasy and lightweight which absorbs straight into my skin. I worried about the strength of the Vitamin C, but so far only a positive reaction!

Finally a vitamin C I like!

5 stars out of a maximum of 5

I'm like goldilocks with vitamin C, they're either too oily or too strong but this one is just right. I have combo skin and my skin just drinks up this gel like formula, I tend to have reactive skin but I haven't had any issues with this! It just leaves my skin juicy and plump. Can't wait to see more results with long term use.

Amazing!!!

5 stars out of a maximum of 5

I've only been using it for about a week but my skin already looks brighter. It has a lovely, non-greasy texture that absorbs quickly and sits well under make up. Also, don't worry if you're new to Vitamin C like me and are worried from the name that it might be too strong - it's perfect for new users or if you have sensitive skin

New summer staple!

5 stars out of a maximum of 5

I've been using this serum every morning for a few weeks and I'm really impressed. It’s lightweight, absorbs quickly, and sits perfectly under makeup. My skin looks noticeably brighter and more even with a healthy glow, the fresh citrus scent is a nice bonus too!

I LOVE THIS

5 stars out of a maximum of 5

I'm quite new to vitamin C but I decided to try because I've heard so many good things. I really like how gentle this is on my skin and I haven't experienced any breakouts or irritation. The texture is the right amount of creaminess while still being lightweight and hydrating. My skin already looks a lot brighter. Think I've found my new summer skincare staple.

I am a huge Medik8 lover and this serum does not disappoint! It smells absolutely incredible and I've already started to notice my skin has a plumper, brighter look - can't wait to see the results in weeks to come! Also, it smells incredible.

New go to Vit C!!

5 stars out of a maximum of 5

I am a big fan of Medik8 products, so was so excited to try this Vit C. I have been using this every day for a week now, and I can already tell a difference in my skin looking brighter and more hydrated. Paired with the Total Moisture Daily Facial Cream and the Advanced Day Ultimate Protect SPF50+ my morning skincare has never been better!!!
