Effective but thin

4 stars out of a maximum of 5

I really liked this serum, which I mixed with The Ordinary hyaluronic acid in the morning, but it’s a bit more watery than my favourite vitamin C serum so I wouldn’t choose to repurchase.

Best vitamin c I’ve tried, it’s like a dry oil so goes on lovely and sinks in quick. Noticed a brightening effect on my skin with regular use.

My favourite vitamin c serum

5 stars out of a maximum of 5

This is the third time I re-purchase this serum. It’s the only vitamin c serum I’ve tried that doesn’t dry my skin out or cause irritation. The texture is like a light oil but it’s absorbed quickly and can be used under moisturiser and make up without pilling. It gives a lovely glow without looking too shiny.

For young skin

5 stars out of a maximum of 5

This is probably the best vit c on the market and great for young skin suffering from acne,  the luxe version for mature is what I (46) use as it’s stronger.  I got it for my daughter (17) who suffered from acne, got treated but has now scars and so this one seems to help her brighten and slowly get rid of the scars on her cheeks .. her skin is dewy and she doesn’t need a foundation to cover

Staple product

5 stars out of a maximum of 5

I absolutely love this product and have repurchased their vit-c serums. They leave your skin so smooth and silky, it's incredible. Super hydrating and perfect also before a face massage. Repurchasing!

Best Vitamin-C Oil

5 stars out of a maximum of 5

Beautiful consistency under makeup, goes a long way. Out of all the vitamin-c serums and oils, this is the best value for money. It’s a quality product and I’ll happily come back to this knowing I’m not wasting my money.
