Medik8 is the best of the best. A pleasure to use without irritation. If you do a bit of research into how retinol is converted into retinoic acid (the good stuff) then you will understand why a retinal is superior to a retinol. If you’ve tried prescription Retin A and don’t like the downtime or uglies, then this is possibly the next best thing you could use. The whole of the Medik8 range is amazing but there’s a reason why this is a cult product. I started on this level 6 without an issue and have just moved to 10 again without any irritation. I would say that I feel a tightness rather than any redness or irritation so follow with a good night cream. Over the years I have used a number of high end brands and also prescription skincare, but I have not gone back ... MoreMedik8 is the best of the best. A pleasure to use without irritation.

I’ve been on lymecycline for the past year for cystic spots on my chin and general breakouts, even when taking this I suffered from monthly breakouts (it was hormone acne that I got when I turned 19). I came off this medicine after bad side effects and was wary of more medicine, so at a dermatologist’s recommendation I tried this. It is a miracle worker. For the first time in 3 years the breakouts on my chin have relaxed and the rest of my skin is glowing, it’s even reducing the scars. If I do get a spot, it lasts for 2 days max which is nothing compared to the 3 week span they used to reside in clusters on my chin/jaw. I really can’t recommend this more, especially if you’re suffering with breakouts. Not only does the rest of my skin look fantastic, but I can ...

Not only does the rest of my skin look fantastic, but I can finally not be worried about those horrible breakouts, my confidence has skyrocketed. Also, experienced no purging/peeling/soreness when following the instructions. Buy this now!!!

I've been using Crystal Retinal for about 5 years now, and recently started strength 10. I am generally fairly lazy with my skincare but this is the one thing I remember at night as it seems to tackle every issue in one easy formula. I have never had a bad reaction to it at all, either on first use or when going up a strength because the formulation is so good. This serum has definitely smoothed the texture on my forehead and brightened my skin. It hasn't completely got rid of my signs of aging, but I am sure it's significantly slowed them down, and people never believe I'm the age I am. I've still got lines around my eyes, and some pigmentation etc but no amount of skincare is going to make a 53 year old look like they're 17. Obviously you get what you pay for, and ...

Obviously you get what you pay for, and this is expensive for some of us, but serums should be the focus of skincare. I can afford to save money with cheaper cleansers and moisturisers when needed, even some SPF, but this & the Press & Glow are where my money goes, and will continue to.

Medik8 Crystal Retinal 1 is the entry level product in the range. I have previously used gentle retinol products like Luna and I have very sensitive skin. Having not used retinal before I introduced this slowly again into my routine. As my skin is so sensitive I normally only use a retinol at most twice a week and started using this once a week. The retinal is a pale yellow lotion it is stronger and a little more drying on my skin but using a good rich moisturiser on top easily prevented any dryness. In terms of results its very effective my skin is much smoother, pores minimised and fines lines less noticeable. I have been using this for months now and 1-2 times a week is still enough for my skin with no irritation at all, once I apply a hydrating layer on top. I ...

My poor skin was acting up ever since I was struck down with covid, my usually clear skin was breaking out in cystic acne on my chin and jawline and nothing was helping. It was really getting me down, then my beauty therapist gave me a sample of this to try. After one use my acne looked and felt less inflamed so I bought the full size and only one week later I haven't looked back. My skin is now totally calm and acne scars from my teens have visibly evened out. It probably sounds too good to be true but this has honestly been a game changer for me. Usually, when I wake up in the morning my skin feels oily - not since using this. It just feels smooth and even. There was no bedding in period either, my skin just took to it no problem so it's strong yet gentle. I'll be ...

I have entered early menopause at the age of 40... exciting times, I know, and appears to be teh gift that just keeps giving. No matter how much I insit that it really shouldn't. With the insomnia, brain fog, depression and constant self-doubt, hormonal changes have rought havoc on my skin as well ushering in waves of breakouts, blemishes, bark cirles, bigger porse and dull looking skin. Since I started using the crystal retinal my skin has calmed down significantly, from day one. I have since started introducing other products slowly to see if I can get my skin back to a healthy glow and am stunned by the results so far. I would recomend any woman struggling with menopausal skin issues try the products from Medik8. I have used De la Mer, Estee Lauder, The Ordinary, ...

Retinol cream has been a game-changer for my skincare routine. After just a few weeks of consistent use, I noticed a significant improvement in the texture and appearance of my skin. My fine lines and wrinkles have become less noticeable, and my complexion looks brighter and more even. One thing I appreciate about retinol cream is how gentle it is on my skin. I've used other anti-aging products in the past that left my skin feeling dry and irritated, but I haven't experienced any of those issues with retinol cream. It's a very lightweight formula that absorbs quickly and doesn't leave any greasy residue. Overall, I highly recommend retinol cream to anyone looking to improve their skin's texture and reduce the signs of aging. It's an affordable and effective product ...

I have been on the hunt for a new retinol cream inclusive of an upgrade on dosage. In all my research Medik8 was highly recommended especially by dermatologist; I’ve also seen them in a lot high end spas so I said let’s give it a try. My first attempt wasn't so successful as I ordered the wrong version (I am not sure how that happened but I had very much difficulty navigating the website to find the product I was looking for in particular). The return process was even more grueling to the point I had to follow up on my return costs. Anyway I said, I‘ll give it another try. I’m only 3 weeks in, on the higher dosage as I wanted (I am an experienced Retinol user) and after my 2nd week, I did notice a little breakout due to my hormones but I have noticed my skin has ...

I’m only 3 weeks in, on the higher dosage as I wanted (I am an experienced Retinol user) and after my 2nd week, I did notice a little breakout due to my hormones but I have noticed my skin has gotten better, less blackheads and actually less deeper pimples. I also notice how much more of a glow my skin is developing and now at week 3, less breakouts overall. I am hoping a couple of weeks more will make the difference but looking forward to seeing how much difference this makes in my overall skin routine.
I have spent 1000s on skincare over the past few years trying to ‘fix’ my imperfect skin. It’s not terrible by any means but it’s not great and has a lot of texture around the nose area. I’ve tried every acid under the sun and strong retinol to no effect. My issue is that I always try and start too strong and as a result over the years I now have sensitive/reactive skin which has meant that I stay away from retinol. Until now. I’ve used Medik8 retinol in the past and got on well so thought I’d give this one a go. I started as described and eased my way in - never done this before either - and quickly was able to get up to daily use. I can’t praise it enough, my skin is smoother, less spots, it kills any spots that do arise and the texture on my nose is disappearing. ...

Crystal Retinal® is a highly effective product for improving the appearance and texture of facial skin. As someone who has struggled with dull and uneven skin tone, I was excited to try this product and see if it lived up to its promises. First off, I was impressed by the packaging of Crystal Retinal®. The sleek, minimalist design of the box and bottle gave me confidence that this was a high-quality product. The bottle itself is small and easy to handle, making it simple to apply the product to the skin. The application process was straightforward and easy to follow. I applied a small amount of Crystal Retinal® to my face each evening, following the instructions provided. Within a few days, I began to notice a difference in my skin.

I also appreciated that the product did not irritate my skin, as I have had issues with other skincare products in the past.
