Medik8 Crystal Retinal 10 - Firming, Advanced Skin Retinaldehyde Face Serum - Night Serum with Hyaluronic Acid and Vitamin E - Gluten Free - 1 oz

Very honest review of a 48 yo with combo skin. Today is exactly 8 weeks since I started using this product, Crystal Retinal 6. I used other retinoid for several months prior, if you have not, you may want to start at a lower concentration. When I started using it I used it every night, again, because I already had a good tolerance to retinoids. I liked it right away, but didn’t review until today. This was the first Medik8 product I bought after research. This is a very good brand and company imo.Here are my impressions of Crystal Ratinol 6: zero irritation (my skin is not super sensitive or dry). Within a week my skin felt firmer. At 8 weeks today the difference in firmness and elasticity is phenomenal. This product is okay to use around the eyes which is rare for retinoids. I have genetic eye begs and puffiness and this product has been more effective than any other I have tried. The eye area is most definitely firmer and more lifted. Major win there.This applies very easily, absorbs very quickly and though it is scented that doesn’t bother me. I have seen many reviews saying that it is sticky or greasy, not in my experience. A little bit goes a long way here (2-3 pumps) as the instructions say. Using too much will make it sticky or even greasy because of the texture of it.Also saw a lot of reviews complaining about the pump, again not in my experience, it actually works perfectly, you get to squeeze out every single drop. I am almost at the end of a second tube and no issues.Also saw a lot of reviews about the tube being small, idk. At 2-3 pumps a night the first tube lasted me 36 days. I think that’s pretty standard for this type of product that you apply to the face AND neck.Some reviewers saw no difference and I am not doubting that but as someone who does a lot of research including speaking to dermatologists, retanal works, Medik8 especially seems to have scientific evidence for its product BUT it takes time and consistency is key. For some people it will take less time and for some more. I saw a difference in firmness very quickly but the softening is wrinkles is taking more time. I truly believe this product is effective but it takes time.I highly recommend Crystal Retinal and am planning to continue using it and go up to strength 10 in a few months.I am also using several other Medik8 products and they are all great. I will however say that it’s better to purchase directly from Medik8 (sorry Amazon) because the brand offers generous points membership, deluxe samples, free gifts and very decent discounts very often.

Medik8 Crystal Retinal 3 is hands down one of the best skincare products I’ve ever used. As someone with sensitive skin, I was hesitant to try a retinal product, but this serum exceeded my expectations. It’s gentle enough for beginners while still delivering powerful results.After just a few weeks of use, my skin looks noticeably brighter and more radiant. Fine lines are less visible, and my complexion feels firmer and smoother. It’s almost like I’ve discovered a real-life filter for my face! The texture of the serum is luxurious, and it absorbs quickly without leaving any greasy residue. Plus, the soothing ingredients prevent any irritation—a huge win for my reactive skin.I also love how Medik8 incorporates retinaldehyde, a more advanced form of vitamin A, making it more effective than traditional retinols but still easy to use. My skin feels rejuvenated and refreshed every morning, and it pairs beautifully with my moisturizer.If you’re looking for a high-performance serum to elevate your skincare routine, Medik8 Crystal Retinal 3 is worth every penny. It’s perfect for anyone starting out with retinal or wanting serious results without compromising skin comfort. Highly recommend!

Visible Results Without the IrritationThis is hands down the best Vitamin A product I’ve used. Medik8 Crystal Retinal 10 delivers smoother, brighter skin with noticeably fewer fine lines—without the dryness or flaking I’ve had with other retinoids. It absorbs quickly, feels luxurious, and the results are real. If you’ve built up tolerance to retinol and want something more powerful yet gentle, this is 100% worth it.

I have rosacea but have wanted to try retinol/retinal. I tried retinol and bakuchiol in the past and my skin didn't like it. Thankfully, no issues at all with this one, and it helped even out my skin a little bit. It was very subtle but that is to be expected with a percentage this low. I have since moved up to Level 3 and when my rosacea is doing really well I can even tolerate Level 6 (but use it on top of a hyaluronic acid serum to reduce irritation). I recommend Level 1 to anyone who is hesitant but curious about retinal.

Really amazing product that has helpedClear my acne and uneven skin complexion. Highly recommend

Pump stops working. I contacted customer support and because I cut the tube to get the product out, the manufacturer refused to send me a replacement. $85.00 and customer service admits there can be a problem getting the pump to work! Don’t buy this expensive item as there are much better, less costly alternatives that actually come out of the tube/bottle/device.

Makes me look younger, at least I think so! If nothing else, I feel younger using it. Soft on my skin and moisturizes just the right amount without irritation. These things are not cheap but this one is the best bang for the buck. I have far less wrinkles around my cheeks.

I tried level 1, 6, and now 10. I think my skin has improved in texture but haven't noticed any real wrinkle reduction myself. No skin irritation. Also use the medik advanced night ceremide moisturizer that was touted to be made specifically for this formula. I have decided to switch from Medika8 retinal (was going to tryout the new 24 formula) to Skinceuticals which is cheaper and highly recommended by dermatologists.
