I really enjoyed using this vitamin C serum, easy pump packaging, convenient and no mess. I liked this cream lotion consistency over the oil liquid drop formula.

I've tried lots of vitamin c serums but I usually dislike the sticky texture they have. Not this one- it's so light and easily absorbed. My skin is looking lots better since I've been using this. I really like it.

I've used many Vit C serums and this one is the best so far. I have 52 yr old skin with mild rosacea and this does not irritate. I'm on my third bottle! It's a light creamy formula that isn't watery and smells very nice. Absorbs well with no sticky residue. Big love

I loved the texture of this product and feel on my skin, so was so disappointing when my under eyes and nose broke out in a red rash after only three uses. After a little research it seems there are citrus oils in the formulation which are the likely cause of the irritation. Sadly I won't be able to use this product which is devastating as it was a decent investment! FYI my skin is also not genera...

This product was recommended to me by a staff member in store. It was a beautiful vitamin C and sat perfectly on skin under makeup. It felt nourishing. I didn't notice any difference in skin texture or dark spots but like with any vitamin C it's about consistency. I'd definitely buy this product again and love pretty much everything in the Medik8 range.

One of the the best vitamin c products I have used. But for the amount received for the price, I go through this too quickly. I have been trialling other products based on price alone.

I am a longer user of SC vitamin c serum and made a switch to give this a try. It is in a glass bottle with pump, keep tidy and no mess. It has a lovely citrus sense and creamy cream texture and I enjoyed it. Hope to have good results.

Delicious dose of Vitamin C

Vitamin C is renowned for smelling "like hot dog water" in some formulations. This lovely light cream serum gives "freshly baked butter cake". Too soon to report on the results, but I know it is packed with active ingredients (just like the brand's Crystal retinoid treatment, which I've used for years and is FAB). In the meantime I just love applying this every morning.

I've been using this (after upgrading from my usual Medik8 Vit C Luxe). I definitely miss the oil consistency of the luxe but I appreciate that this formula and bottle is more stable (less oxidising). There's also less waste which is a bonus. My skin is looking great so I assume it's working well.
Best texture vitamin C serum

This has THE best texture of any vitamin C serum that I've ever used. It's a creamy serum rather than being liquid and sticky like others. It also doesn't make my skin feel sensitive or stingy. I haven't noticed any dramatic results in the weeks I've been using it but vitamin C is often subtle so that doesn't mean it isn't doing anything. I love that there are exosomes included in the formula as w...
