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

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!

I'm an avid user of gentle acid exfoliation for years (BR P50). I'm 35 and I wanted to step up my game. This really made a difference. Every morning, when I wake up, I definitely noticed that my frown lines have just went away. I've been using it once a week for three months now. It's incredibly soft in texture and does not smell bad. And it hasn't irritated my skin one bit.

Fantastic product. I’ve noticed improvements to my skin within two weeks. No irritation on my sensitive skin.

I like the product but it was definitely a used tube or got messed up in production. The pump only lasted for about 2 days and totally quit. Because I wanted do much to try this product I cut the corner off the bottom of the tube because I couldn’t get the pump off. Now I can squeeze a little each day. I’m not sure I see any visible difference yet but will move to the serum when it’s gone. Hopefully the packaging will be better and the entire amount will be there.

This was perfect for my beginner retinol. I loved it & def can tell the difference. Super light weight & nice light scent. Absorbs quickly & well. I just finished it (lasts a long time- little goes long way) & moved up to the 6 in this line.

can even be used on the neck it is that gentle yet it works. I have used many retinol creams over the years, started having them prescribed by my doctor, but after finding this I am sticking with it.

Do not waste your money. It is too expensive to have such cheap packaging. The pump on my brand new bottle worked once and then never again. You also cannot unscrew the top so the only way to get the product out is to cut it open. It won’t last long that way.

It's the container I have an issue with. The pump action is pretty useless. It doesn't draw the lotion up the tube. I will have to remove the top and try to get to the lotion another way. For the price, I would expect better quality. I probably won't reorder
