Love this
I was a bit worried having never used any vit c serum before that with this being a potent one that my face might react badly but it's been fine. I have used every other day initially. I use after hyaluronic acid and my face drinks this stuff up and the flows for the rest of the day. Felt a difference since day one. Skin is super super soft on the days I use this. I only wish I had known about this sooner. Will definitely be buying again

Tried and True
I cannot fault this serum. It leaves my skin looking lit from within. I've gone through bottles of this over the years and can't bring myself to stop. The fragrance is very light, citrusy and inoffensive. It sinks into the skin fairly quickly and I have noticed a long term difference in the dullness of my skin. It's no miracle serum but consistency and using the right products alongside it, is key for proper results.

The fragrance is very light, citrusy and inoffensive. I keep thinking I'll try the next one up in the range but having tested it in store, I can see why it's not as popular as this one. Very pricey but I always wait until there's a sale on. Would definitely recommend!

It’s ok..
First impressions and I’m not overwhelmed. It’s quite an oily product which seems to just make my make up slide off but my skin does feel softer and more brighter with only a few tries. I love the crystal retinal from this brand and it is worth every penny but so far I’m not sold on this.

Does brighten skin
I bought this to help with pigmentation; while I think it's helped a little bit, the serum does definitely make your skin brighter and is really hydrating. A little goes a long way, too - use it sparingly.

Love it
I’ve been buying this for a while now. Feels great & leaves a great glow on its own or it’s easy to wear under make-up. Just let it sink in a bit before applying moisturiser etc

Great vitamin C
This is quite a strong product and it took a while for my skin to tolerate it. After a while, my face has become more radiant. Smells delicious too!
