I have been using Serum 1 for past few months and decided to switch to Serum 3. no side effects. Skin looks refreshed. Absolutely love this product

So good!

I got this in one of the cult beauty boxes (a full size!) and have been using it as part of my routine ever since and only just repurchased another. It feels amazing on the skin and really brightens and tightens. I don’t think i could lose it from my skin care routine now.

not perfect

I like the way my skin feels after just using it, pity it really dries out my skin and it looks like dry when I wake up (after using it in the evening). Will try to use it summer, cause in winter - no go for me.

Amazing

This product is amazing. I find a lot of serums and moisturisers just sit on my skin feeling tacky, but my skin just soaks this right up. I started with CR3 and am using every day without any irritation (my skin isn't sensitive). I can already see improvements in my skin after a few weeks and can't wait to try CR6.

Good product slight drying

This does noticeably make my skin firmer, smoother and brighter. The only down side is it does feel slightly drying when I put it on but I just layer it with a rich moisturiser after 30min or so and its fine. Looking forward to moving up to CR6.

Good results!

Good results after using for just a few weeks. Nothing amazing yet but it has only been a few weeks so patience is the key

Perfect retinol for beginner

Made miracles to my congested and acne-prone skin. Highly recommended!

Godsend!

Had low expectations because my congested skin hates retinol, I’ve tried them all including prescription level. This however is doing nothing except benefiting my skin, I have had a little purge in places but they are disappearing fast rather than escalating, I’ve even used it on my most congested areas which has been a disaster in the past! Using twice a week and already my skin looks better overall and feels softer than it’s felt in years. Very ££ but really worth it.
