Love love love
I love this vitamin C! I’ve used it for years and it’s so lightweight that you can barely tell that you’ve got it on. I’ll never switch to a different vitamin C

Undecided
I have been using this serum for a few weeks now, and I do think it has helped fade some of the pigmentation left from spots, and has helped even out my skin tone overall. However, I don't really get on with the texture; it has a sort of dry oil consistency, which for some reason on my dehydrated skin makes it feel tighter when applied?? Not sure how that happens... Also, because of the oil content, it doesn't always play well with other products. You should always apply Vit C to the skin as the first step in your regime after cleansing, but for me this can cause pilling when applying another serum or moisturiser on top. So I like the results, but I don't get along with the feeling unfortunately. Shame as it's a good price and a little goes a long way! Much better value for money than it's more expensive counterparts, but I think I will go back to Summer Fridays CC Me Serum.

Great
Love this, not sticky at all but leaves a nice soft glow look and feel to skin, almost like a facial oil but not as thick as one. Face definitely looks brighter when using.

It didn’t irritate my skin
I have tried several vitamin C serums before and they have all irritated my skin; however, this one seems to be the one! I have used it for the last two weeks and my skin is alright - no reactions!

On my 3rd bottle
This stuff has transformed my skin. It actually smells quite nice, a bit citrucy, and it sits nicely under other skincare products and makeup. It was so good that I've bought a few other things from the brand!

Soft skin but not any visible change
My skin feels lovely and soft after using this, and I love the texture and smell, but I haven’t noticed any change in radiance or really texture since using it. I’d probably buy it again to keep going.

Staple in my skincare routine now
I have struggled to find a vitamin C serum/cream that didn’t make my skin greasy or cause breakouts but I decided to give this a try. The formula is so lightweight, absorbs well into skin and you need just 5 or so drops so a little goes a long way. I’ve noticed a huge improvement in my otherwise dull skin and now I can’t go without this product. Love it!
