Rated 5 out of 5 by from Love I love this product it smells wonderful and definitely brightens skin for a warm glowing complexion but do be aware the first couple of times it can sting it does subside but I always feel like it makes it feel like a product is working. It’s not the cheapest but It’s so good.

Rated 3 out of 5 by from DID NOT SEEM TO DO MUCH AT ALL This has a strange almost paste like texture rather than a traditional serum which is usually a liquid. After application, it gave a matt finish to the skin and it felt like it made my skin a little on the dry side. Having used the serum every day for a few weeks now, I can see no real difference to my skin.

Rated 4 out of 5 by from So far so good.... I was lucky enough to receive a couple of samples of this a while ago. Started using about 10 days ago.... I have decided to use the samples on the fine lines above my lips, my crows feet and the nose area of eyes.... I thought this would be a good I am not sure whether it would work on wrinkles...but who knows? Anyway, it is quite thick so only need a small amount, feels lush and soon seeps into the skin to give a dewy look. The areas I use it on look very well moisturised and fills in the lines at present. Whether it will finally irradiate the fine lines who knows....but at present I enjoy using it and if it gives me my long term goals of loosing the fine lines...I will be buying for sure..

Rated 5 out of 5 by from Smoothing silkener I had a tube of this concentrate in one of the SpaceNK gifts. I hesitated to try it as Vitamin C can irritate my skin, but decided to try it initially on a small section of my face. There was no sensitivity, and the formula feels marvellous as it sinks in. Quite thick, it almost seems to be filling in rinkles as it goes on. The skin feels silkier, smoother, more even altogether.

Rated 5 out of 5 by from Absolutely lush! This vitamin c serum is lush! The texture is so nice, it’s thicker than lots of other vitamin c serums I’ve had. I love how it isn’t sticky, that is also a trate of other vitamin c serums. I would defiantly buy a full sized bottle. It would also be nice to put on the back of your hands for sun spots. Brilliant product!
