Love love love

Absolutely love this retinal and would never switch. Enjoyable to use. I trust the ingredients and medik8’s formula’s. No irritation and improvement in my skin. I used to have acne and went on roaccutane. Introduced this at the lowest strength shortly after coming off and gradually increased strengths based on medik8’s guidance. This has definitely helped keep those breakouts away and clear up any post inflam pig.

fantastic results

I've used Medik 8 since about 2020 and started at number 6, having previously used Drunk Elephants A passioni, so can tolerate quite a strong retinol.   This caused no irritation at all.  I'm 53.   The texture of my skin is now much more smooth and  I can see  It has definitely minimised my some faint lines on my forehead and very noticeably minimised fine lines around my eyes (I don't have any deep wrinkles).   I am about to finish my second tube of number 10, and have already bought no 20.  It's one of those products that isn't the cheapest but it's so consistently good, I would rather spend less on a moisturiser/cleanser than stop using this brand.  I don't really understand the strength of retinal, compared to retinol, but the results I see feel like it would compare to a pretty potent retinol.

Medik8 is the BEST!

The titled says it all… started using medik8 a few years ago and there hasn’t been a product I don’t like yet. I’ve built up the retinol and I’m now on 10. It’s smoothly applies, doesn’t dry the skin too much (slightly drier until skin gets used to it) and I’ve definitely noticed a difference in my skin texture, pigmentation and overall glow!

Cult classic

This has completely transformed my skin. It's gentle enough to use most evenings and has reduced my fine lines and really freshened up my complexion

Best Retinol Brand

I love Medik8's retinols. I was using the crystal 6 before and recently upgraded to the 10 and comapring with other retinol products I enjoy this the most. My skin doesn't get sensitive from it and I visible notice my skin is improved when using it.
