## Description

Powerful retinal serum delivers 11x faster wrinkle reduction than retinol. Improves skin texture, brightness, firmness, and clarity with a vitamin A-based formula.

Review: Excellent retinal based product - The best retinal based product I have tried so far, better than retinol as it is a direct vitamin A extract. I've been using retinol for a couple of years and no 6 suits my skin, gentle and powerful. I can see the difference around my eyes and smile wrinkles. I wish I'd discovered it sooner. On repeat for me!
Review: Best Retinal I’ve ever used! It works for me! - This has to be the best retinal product I have used. (And I have tried most of them, murad, ordinary, the list goes on.) Ive been using this for about 6 months now. I started off by using the retinal 3 progressed to 6 and I’ll go on to retinal 10 next. It’s creamy in texture, smells pleasant and is absorbed into the skin almost immediately. My skin is on the sensitive side and this retinal has never caused me any problems even though it’s a lot stronger than ‘retinol.’ My skin feels and looks smoother and hydrated, my deeper lines have been drastically improved, and although you can’t expect the results of a face lift it’s made a big difference to how I feel and look. It’s especially helped with the finer lines around my lips. One tube does actually go along way (mine lasts months) and I apply it every evening before bed without fail. I only use one pump full on one side of my face and one pump full on the other before using a smaller amount on my neck. Dark spots have been reduced and my skin texture looks more even. When you get to the end of the tube and nothing more comes out cut the tube in half as there’s still stuff in there! I always look out for this when desertcart are doing special deals or offers and usually can get it when it’s at its best price.

## 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.

## Questions & Answers

**Q: Should I use it as a serum or a cream?**
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.

### ⭐⭐⭐⭐ Great retinol but buy with caution if you have sensitive skin.
*by L***! on 9 December 2025*

I have used the retinol 3 for a while so decided to upgrade to the 6. Although this works for a lot of people it caused an excema flare up on my face so may be too strong for sensitive skin.
