    THE BEST THING EVER!!

    I have struggled with acne/ scarring for years now and have tried every skincare under the sun. I started using retinol last year and have never looked back. I have less breakouts (I did purge when I first started using) and so much less scarring/ red marks. If you struggle with this too, then i definitely recommend you buy this!

    Finally starting

    I was worried about retinol but I’m now 30 and I’m starting to feel conscious and bothered about forehead lines showing more and more - I use this sparingly just on my forehead a few times a week and it’s definitely helping - initial breakout but that’s eased right up as I’ve got used to it
