Good

This is a nice product, easy to use. Seems to have had more effect on my hands than face though.

Retinol beginners

I’m 24 and have just began retinol journey, I’ve heard this is a great one to start with (I have the 3 strength) I’ve only used twice so far in the pm so too early to review long term results. Haven’t had any sensitivity issues- I’m waiting for the purge to begin but so far I like this one tube is suppose to last up to 6 months as you only need a tiny amount.

Really enjoyed!

I have quite sensitive skin and retinal often can make my skin really dry and flaky. This didn’t at all, my skin was absolutely fine with it and I’ve definitely noticed a difference, I get so many compliments on my skin!

Lovely product

Used over retinal serums that were constantly drying out my skin and making it sensitive so switched to this and not had those issues with it, and has improved my skin appearance so much.

Amazing!

Absolutely amazing! I love this product, I’ve stuck with the 3 version but I think I definitely need to go to the 6 to see even more benefits. Works incredible on the skin and has made me glow!
