Love it

So far so good - haven’t had any adverse effects - used every other day for a week and then every night from then on. No irritation no peeling. Skin is super soft I’ve seen a massive reduction of the tiny blackheads that have plagued my skin lately.  And best recommendation is - my husband said my skin doesn’t look as lined -looks  dewy and fresh. What more can you want. Definitely will be buying again

THE BEST RETINOL

This is the best retinol I’ve ever used. I have seen great results, including super smooth skin. I have never experienced irritation with it

Good starter retinol

Lovely retinol, been using for a few months and I’ve noticed a difference in evenness of my skin. Will continue using to see if I’ll see any further change

Medik8 Crystal retinal 3

Although I have been using a retinoid for some time and have been pleased with the results, I decided to try the Medik8 retinal 3 on the recommendation of my daughter. I had no need to phase it in (as an experienced user). My skin tolerates it really well, looks clear and smooth. I aim to move up to retinal 6 when I finish this product. It seems like a kind and gradual way of moving to higher strengths and hopefully improved results.

Absorbs quickly

I want to love this and it has all the makings of a great product but I just can’t seem to get past the Retinol nasties! The product itself seamlessly absorbs into the skin, I wake up with the softest skin but I think it’s just too high a % for me. Im going to drop down a % again to see if I get a better result.

Amazing serum

As a first-time user of retinol, I wasn't sure whether to go straight in for the Medik8 6 or the Medik8 3 serum, as I've used acids for a good few years now so was tempted to go straight in as my skin is used to harsher products and doesn't tend to react. I chose to go for this one to 'dip my toes in' after reading the reviews, and I'm so glad I did. I'm currently using it every other day at the moment (it does say I can go to every day in a couple of weeks) but the difference in my skin is already noticeable. It's much clearer - it hasn't done too much for the wrinkles yet, but my skin is definitely plumper and my skin barrier much better. I wouldn't hesitate to recommend this product to first time retinol users - amazing.

Great starter retinol.

Low enough strength that any negative effects have been minimal to non-existent, but notable improvement in skin pigmentation and fine lines after a month of use - will be moving up to the next strength after this one is done, and would massively recommend as a beginner retinol.
