I read the reviews and went straight for serum 3, I have used other retinols previously. I have been using this nightly for a month now and my skin is noticeably brighter, firmer and more hydrated. I haven’t had any irritation either. Definalty going to purchase the retinal eye serum next.

Best retinal product

If you are new to retinal products I would recommend starting with this Medik8 retinal. It is gentle and non-irritating on the skin. I have been using this nightly and am starting to notice a difference in my skin with fine lines being less noticeable.

Good retinol choice

I’ve used a few different retinol products and this is my favourite so far. It doesn’t cause irritation or dryness. It improves my skin texture and isn’t too pricey really.

Good Product

Non-irritating and feels good on the skin! Good strength for an over the counter retinoid. If you want to make an actual difference, I'd recommend a tretinoin prescription!

Good Starter

This is a good starter retinol. I’ve used multiples so didn’t need to phase it in, just went straight to nightly application. Didn’t cause any breakouts and my skin texture is better. Haven’t noticed a huge difference in fine lines yet but it has only been 1 month.

Good beginners retinol

I ordered this having heard fantastic reviews. I love the packaging- a tube with a pump which makes it easy to control how much is dispensed. The product itself is as pictured, an apricot coloured lightweight cream which I found to absorb easily into skin. At first, I couldn’t see any difference but after a couple of weeks of consistent use, my skin looked fantastic! A definite improvement! This is a good retinol choice for beginners- I experienced no irritation either.

Good reviews

I’ve been happy with all of the other medik 8 products I’ve tried and as they have an extensive retinol range it looks a good option to try!
