Medik8 Crystal Retinal 6 - Brightening, Firming, Advanced Skin Retinaldehyde Serum - Smooths Wrinkles - Hyaluronic Acid, Glycerin, Vitamin E - 1 oz

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.

Holy grail product that I will be re-purchasing in the next level once my current tube runs out. I absolutely love this product and my skin feels supple and amazing after using. Make sure NOT to combine with other “active” products like vitamin C or exfoliants. I use every other night in my routine, it layers beautifully, and is perfect.The only downside is it’s a bit pricey, but truly worth it in my opinion.

Excellent product. I’ve used retinal for several years, but I started with the number six, but will go up in strength as I re-order.

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.

Medic8 retinal serum improved my skin so much that I can’t imagine going a day without it. Not harsh even for sensitive skin contrary to many other retinol products. Absorbs quickly, doesn’t make your skin dry. Helps prevent breakouts. Don’t forget to use a nice moisturizer with it.

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.

Love this retinol. Great product

A couple of reviewers commented on the scent and I thought, how bad could it be? Well it's bad. And it's definitely not for sensitive skin. The scent is what I figure made me break out. I have used other retinol products and not had the same problem. Skip this one.
