One of the best Vit C serums I’ve tried

5 stars out of a maximum of 5

I really like this serum. I’ve tried a few including Murad and this sinks in well and makes my skin feel bright and clear. This is my second bottle and I will purchase again.

My favourite vitamin C

5 stars out of a maximum of 5

I really notice the difference when I don't have a bottle of this. It's the one product that I always recommend to friends to help with radiance and anti-aging. It takes a little while to sink in (I use it in the mornings), but it has dramatically improved the quality of my skin and sits well under makeup.

The perfect vitamin c serum to wear during the day. Luxurious packaging, great product, with a nice scent and a good price point. I've already repurchased

Great!

5 stars out of a maximum of 5

This is one of my very favourite vitamin C serums. It absorbs well, does not irritate and does improve the look of my skin. I've been repurchasing for a very long time.

Good

4 stars out of a maximum of 5

Good - it smells nice and doesn't have that horrible Vitamin C lingering smell. It settles nicely on my skin but I haven't noticed too much of an overall improvement.

Gentle yet effective

5 stars out of a maximum of 5

I have struggled with vitamin c creams and serums in the past. Often they sensitise my skin leading to eczema. This serum is the first to feel comfortable on my skin and I've had no irritation at all. My skin is glowing and I'm looking forward to seeing the results over the next few months

Lovely

5 stars out of a maximum of 5

Have been using this for a few weeks now and really loving it!  I was a bit worried with it being an oil texture but it’s so light you’d never know it was an oil.  Soaks in beautifully, goes well with my other products and makes up wears perfect with this too.  Will wait to report back on the effects I find but so far it has definitely evened out my skin tone & gives it a more ‘fresh’ appearance.
