Review: Better than retinol for sure!!! - I’m 48 with wrinkes but Medik 8 helps my skin to help my skin to looks smoother and my wrinkles improved, I started with lower Medik 8 and moved to retinal 6 and I can that my skin gets better and better! This is is an advance cream and defintely better than retinol, a bit pricey and worth every penny! I highly recommend it and you wont regret it. On e thing that you need to be aware of, this makes you skin a bit dry for start until your skin get used to it so make sure that you apply moisturiser after!!
Review: Amazing, makes a huge difference - I’ve worked my way up to retinal 6 and it’s a great formula. Really makes a difference to the tone and brightness of my skin. Looks much clearer. I use this each evening & a red light mask in the mornings.

A: Hi, thanks for your question - Crystal Retinal 6 is an emulsion-based serum that is designed to be worn underneath a moisturiser to keep the skin hydrated. Our Advanced Night Restore is ideal to apply on top as this contains Advanced Ceramides and has been optimised for use with Vitamin A such as Retinaldehyde. Thanks, Medik8.

### ⭐⭐⭐⭐⭐ Amazing, makes a huge difference

### ⭐⭐⭐⭐ Nice product - on the expensive side as you move up to stronger levels
*by B***E on 26 August 2026*

I've been using this for around 6 months now after using the Retinal 3 for a year before it. Feels like a nice smooth product to use, not heavy feeling on your face. I always apply a night moisturiser over the top after letting it sit for around 30 mins. In terms of effectiveness, it's hard to say. I think of it more as a preventative and wasn't expecting it to reverse fine lines etc. My partner is now on a stronger version - I think 20 or 30. What I have noticed is the colour! The stronger you get, the more orange it makes your skin after application. Definitely a product to be used once you are in for the night! I feel the tube lasts a while - a few months when used only on your face. There's quite a jump in cost as you go up the levels which I feel does make it quite an expensive product.
