## Description

Gesichtsseren

Review: Super - What to say 🙌🏻🙌🏻🙌🏻Amazing product. I found it because AI advice me for improving my skin . I’m been using it for few weeks, but already have super results.
Review: Promising start! Gentle enough for a retinal beginner - I’ve only been using the Medik8 Crystal Retinal 6 for about two weeks now, so it’s definitely still early days, but I’m really happy with it so far. I was a bit nervous about moving up to a strength "6" right away, but the formula is surprisingly creamy and hasn't caused any of the typical redness or peeling I’ve had with other retinoids in the past. It has a slight apricot/cinnamon scent that’s actually quite nice, and it sinks into the skin almost instantly without leaving a sticky residue. Since it’s only been 14 days, I’m still in the "phasing in" period (using it twice a week), so I haven't seen any dramatic changes in my fine lines just yet. However, I have noticed that my skin looks a bit more "awake" and glowy the morning after I use it. It definitely feels like a high-end, stable product that is working behind the scenes. I’m excited to see the results once I finish the tube and can use it more frequently, but for anyone worried about sensitivity, this is a great, gentle place to start.

## Features

- FAST WRINKLE REDUCING POWER - Wrinkle reduction with just 1 tube. Retinaldehyde works up to 11 times faster than classic retinol.
- RADIANT, YOUTHFUL SKIN - Delivers remarkable visible improvement in texture, brightness, firmness & clarity. Vitamin A is a key pillar of Medik8's simple yet effective anti-ageing strategy of using vitamin C followed by sunscreen by day, and vitamin A at night. This is called the CSA philosophy.
- PROFESSIONAL-GRADE RESULTS- Our iconic retinaldehyde serum boasts antibacterial properties to help target blemish-causing bacteria for visibly clarified skin. Our formula features key ingredients: Hyaluronic Acid, Vitamin E and Glycerin.
- HOW TO USE - Step 1: After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser. Step 2: For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night.
- PROGRESSIVE STRENGTHS - Our unique ladder of 5 progressive strengths (0.01 - 0.2% retinaldehyde) means you can keep experiencing ever-improving benefits that tackle the most stubborn fine lines, wrinkles and dark spots.

### ⭐⭐⭐⭐⭐ Better than retinol for sure!!!
*by S***7 on 2 August 2026*

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!!
