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.

Reduces pigmentation

My scars and pigmentation significantly reduced after using a bottle of this Vit C!! Always on the repurchase this.

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!

Morning ritual

Use this in the morning and my skin definitely looks brighter, a little goes a long way too.

Lovely smell, unsure how effective

Smells like oranges which is lovely. I don’t notice any difference in my skin but maybe I needed to try it for longer! It did go on nicely and make my skin feel soft!

Good vitamin c.

I’ve tried a couple of vitamin c serum and this one has to be one of the best. Price point is good for the brand. The consistency of the product is really good and it absorbs quickly enough for a morning routine. Also really like the smell of this one, orangey but now overpowering.

The best

My skin loves products of this brand, serum with vitamins c and e is no exception, I use it during the day, leaves no film, absorbs quickly, moisturizes, nourishes, skin glows with health
