Amazing

Started off with number 3 Then went up to number 6 then 19 use that twice then 20.  I have tried many retinol products over the years And this by far is the most gentle and works great and hand in hand with the vit c in this range.

Smooth clear skin

Perfect step up from using the 10. It’s just the strength I needed. Helps resurface my skin and also helps with additional breakouts. Love.

Game changing silky night Serum

I'm a huge fan of medik8 and was super excited to get my hands on the next upgrade to my evening retinal serum! Over the last few years I've built up from 3% to 6% before progressing to 10% over Christmas. Since building in the 20% into my routiene once a week over the last month I am amazed with the results, the retinal serum is super gentle. I pop it on before brushing my teeth to allow the serum to properly soak into my skin and then apply my Medik8 night restore moistorisure which is also incredible. Top top as the serum is a much darker yellow / orange make sure to let it really sink into your skin before your face touches the pillow with lighter linens!! I cant wait to see further improvements over the next few months of continued use, but so far it's great.

Gold Standard

Medik8 are pioneers in the field of retinal and they haven't been bettered. So pleased to see the top strength version here - game changer as with rest of tiers. Build up to it but worth the gradual progression.

Love, love LOVE

I absolutely love this - I regularly use the Medik8 retinal and have been slowly building up my strengths and this has already started to leave my skin clearer and brighter! I have had no issues whatsoever (no reactions or breakouts) and can see this being a forever staple in my routine.

Top tier for retinol pros!

If you're experienced with retinol, this is a must-have. Even though it's got a high potency, it doesn't feel too harsh on my skin (but again, this is because I'm a retinol pro, so don't jump straight to 20 before working your way up there). Since using this, my skin's radiance has improved so much and I can't wait to see more enhancements as I keep using it.

A true miracle worker!

As someone with dry skin, I need to be careful when selecting which retinal to add to my routine. For years now, I’ve been turning to Medik8, as it not only visibility brightens and smooths my skin, but it doesn’t strip it of moisture. As an avid retinal user, I was so excited to try this stronger Vitamin A and it did not disappoint! At first, I layered it over my moisturiser so it acted like a buffer but now I use it every other evening and I’m already seeing noticeable changes. I can’t wait to see the long term results!

No Irritation!

I've been a loyal Medik8 Crystal Retinal user for years having worked my way up to 10, so jumped at the opportunity to try the new 20 strength. As this is double the strength of my usual, I was admittedly a bit apprehensive to try this (although I have normal skin and never reacted to actives before) and concerned about my skin drying out or peeling. I needn't have worried. Whilst only using for 3 weeks now, I followed their advice to gently work up to daily use over the course of a few weeks and have experienced no irritation whatsoever. I'm already noticing the results; more even complexion, less breakouts and softer, more supple skin. I can't wait to see the results after a few more weeks. The only downside (and by no means a deal breaker) is that it does leave you with a slight orange hue when applied but as it's part of my evening routine, it's doesn't bother me at all.

Amazing upgrade

Absolutely love this step up in strength of my favourite retinal. I do have to caveat that I am an established retinal user - having been consistent with the 10 for the last year. My skin is super sensitive but had no issues at all - no reactions and no breakouts. After 4 weeks of applying the 20 3 x per week my skin feels plumper, clearer and much more robust and glowing. Definitely a keeper in my routine!!!

Love!

It's safe to say I love this retinol! I'm a regular retinol user and didn't experience any redness or sensitivity at all. My skin looked noticeably clearer and brighter, and it cleared up a stubborn pigmentation area on my cheek. I'm using less make up as a result and it's taking me less time to get ready in the morning! It's a win from me :)
