- Crystal Retinal 3 - Firming, Advanced Skin Retinaldehyde Face Serum - Night Serum with Hyaluronic Acid and Vitamin E - Gluten Free - 1 oz

This product is truly a 10/10 for me. The quality, texture, and formulation feel very premium, and I love that it uses retinaldehyde instead of traditional retinol. It feels effective while still being comfortable on my skin and has become one of my favorite nighttime skincare products. The price is higher, but the quality of the formula makes it feel worth the investment.

I have mild rosacea tendencies, so I was worried that this would worsen my redness, and it hasn’t at all. I really feel like this has improved the texture of my skin overall, and immediately after applying my skin feels moisturized and very smooth/soft.

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!

It’s a good product and has a very pleasant scent. Just one note: I don't think there's much product in it—I'm not sure if it was just the specific one I received, but it felt like it was lacking product.

I’ve tried many retinols, retinals and had a brief stint on tretinoin, but this is hands down my favorite, and has been the only one I’ve stuck with.I have sensitive & aging skin, but had zero irritation or break outs from this.I have used most of the level 3, and am now using the level 6 (whilst using the rest of the level 3 under my eyes). I put it on clean dry skin, and then follow up with a thick moisturizer at night…During the day I use moisturizer and spf (do not use this if you’re not going to use spf. Also, don’t combine with other actives at the same exact time. I will use a light AHA exfoliant once a week and will not use this on the same day… I did not add in the AHA until about a month in, to ensure no barrier damage/irritation)And for people saying the package doesn’t work, it DOES work. Push the product toward the pump (as you would with toothpaste) and then use the pump. Sometimes you just have to push it toward it to get it to dispense. I actually really like the product as it’s airtight and keeps it stable, if you cut it open you are ruining the product.And as for the scent, it has a very light scent that is actually cozy. It kind of smells like light vanilla cookies. I’m not usually a fan of scents, but actually enjoy this one. If they made it in a hand/body lotion, I’d buy it lol.I’ve been consistent, seen good results so far and will continue to use this product; happy I’ve finally found a form of vitamin A that agrees with my skin.

Worth it to buy

I have very fair, sensitive and dry skin. Have never used retinol and was worried about side effects. Had no trouble using this every night. Definitely feel the dry cells regenerating and skin looks more glowing. Smell is like faint cinnamon roll like someone else said.

I was really surprised at how small the container way. My skin barrier is pretty strong due to skin procedures and medical grade skin care I use so I think I could have gone up to Medika-6. I use nightly with no issues but a little dryness, Honestly, fo the price, I'd rather get Rx resin-a.

El producto es excelente pero el empaque llegó mal y parece que no traía todo el producto.

Excellent !

Effective

Very disappointed with this product, very small amount of product and the pump does not work. Will not be purchasing again.
