Julie: about a week ago

After 6 weeks of twice daily use I noticed an overall brightening and more even texture of my skin. The price for 30ml at 25% Vitamin C also makes this product a great investment. Will repurchase.

Sheila: a couple of weeks ago

I have been using this for over a year. It has a nice brightening effect and does not irritate my skin. The texture is rather oily/siliconey but since my skin is on the dry side I don't mind it. I don't think it has made a difference in age spots but since Vitamin C is important in anti-aging skin care to help offset negative environmental damage I continue to use it as a preventive measure.

I've been using this serum for almost 3 years now, after having tried many other vitamin C serums - it's incredibly effective for brightening and evening skin tone.

Louise B.: a few months ago

Love love love these drops! I have quite dehydrated full skin and these plump my skin out and give me a glow.

Irmgard: a few months ago

This is very good for my skin but I find it a bit sticky ontop of the skin, it should soak in better. Otherwise I love it

Dani: about a year ago

I really do love this Vitamin C serum. I have the Vitamin C suspension from The Ordinary (sister brand) but that ine has a gritty texture and according to someone who works at one of Deciem's shops in Toronto (they call themselves "Monkeys", it's the least effective and most irritating. I feel no irritation from this and it really does brighten and even the skintone over a while of using it consistently. I have only 2 complaints.... 1) because I'm an oily skinned gal, I really could have done without an oily serum and 2) it's hard to layer over or under other serums. I think because it's oil-based, it just doesn't play nice with other more water-based serums and actually lifts them up and causes them to pill. This one is best used on clean skin, alternating one day with this and the next day for your other water based serums.

It's early days but so far I love what this product is doing for my skin! It does appear more even & less dull...such a pleasure in the dead of winter.

Kathryn: more than a year ago

This is a wonderful Vit C booster serum which adds a very important step in the skin care routine. I do like the difference in my skin since starting this product and will continue to buy and use. I prefer it to any other Vit C product I've tried.

Peiji: more than a year ago

I've used many vitamin c serums and this is the first one where I have repurchased. I do notice a difference in the texture of my skin and I highly recommend it. It might not work for everyone, but definitely worth a try! It is kind of pricey, but it does go on sale!

LB: more than a year ago

I've used this for about a month and a half, and I'm really pleased with the results. I use it after a glycolic acid moisturizer, or if I need extra moisture I mix it in with an overnight moisturizing mask. My skin definitely seems like it has more clarity and more of an even texture. Would recommend to others !
