Newbie to retinal

First retinal I have used but pricey but worth it been using for about a month and my skin is looking a lot smoother and no longer suffering with the bumps under my skin. Can leave the skin dry so will need a thick moisturiser on after

Amazing

I’m fairly new to retinol but this is great. Not irritating to the skin and have seen great results using 3x a week!

Amazing

I love this product it’s very good if your stepping up from your first retinol and incorporating into your routine a few times a week.

Irritiating

I would prefer it to be without fragrance. My skin seems to be irritated while using this and is hard to say if this is from retinaldehyde of fragrance.

Love!

Love this product. I have very sensitive skin so always a bit worried about starting retinal, but this didn’t sensitise my skin at all and was lovely to use. Nice texture and smell too which is a bonus!

Best anti ageing serum

I have been using this serum for now 2 years almost. This has made my skin more refined and I don’t get breakouts anymore.

First time retinal user

So happy I took the plunge and invested in this product. Can see a reduction in my sun spots and my skin tone is much more even. Haven’t yet seen a massive difference with my wrinkles but this is a marathon and not a sprint right?! Feels lovely when it goes on and sinks in so quickly.
