Enhanced with hyaluronic acid, vitamin E, and patented encapsulation technology, it delivers radiant, youthful skin with minimal irritation. Designed for experienced vitamin A users, its progressive strength system ensures continuous anti-aging benefits while being dermatologist recommended and vegan-friendly. ## Description Reveal younger-looking skin with just 1 tube of Crystal Retinal. Our iconic vitamin A night serum contains next-generation retinAL (not retinol) which acts 11x faster than retinol, to visibly smooth, brighten and firm skin. Unlike others, our internationally patented stability system ensures maximum retinal potency and effectiveness until the very last drop. All this without irritation, thanks to our industry-leading encapsulation technology which delivers gentle yet powerful results - even on sensitive skin. 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. Crystal Retinal is THE age-defying night serum for every serious skincare routine. Review: I can't speak highly enough of Medik8's retinol range - it's kind enough for my sensitive skin, the cream formula minimises the risk of it degrading, and the different strengths mean you can adjust daily based on what your skin is doing. I've been using 6 & 10 for some time now, and dared to venture to 20. It's noticeably thicker than 10, and also makes your face shockingly yellow (this is a sign of good quality retinol, apparently), a little sticky on the pillow. But despite its strength, I've had no irritation, using once or twice a week, alternating with 10. I always us a peptide first (Medik8 or Vichy89), and if I notice any dry or tight patches, I revert to 6 for a few days. I've used retinol for so long I wouldn't have a skin 'transformation', but Im in no doubt that retinol has been keeping my skin texture in good nik, and this is by far one of the best I've used. Review: It cost more than I usually pay but thought I would give it a try. To be fair I haven't used it religiously or regularly. It didn't cause any rash or burning. I can't see myself purchasing it again, probably hype. I read that retinal content has to be very high to be effective and these creams are only available on prescription, used for burns victims etc. ## 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. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0BKLR7TXT | | ASIN | B0BKLR7TXT | | Active Ingredients | Retinaldehyde, Hyaluronic Acid, Vitamin E, Glycerin | | Age Range Description | Adult | | Best Sellers Rank | #3,899 in Beauty ( See Top 100 in Beauty ) #34 in Facial Night Creams | | Brand Name | Medik8 | | Container Type | Tube | | Customer Reviews | 4.2 4.2 out of 5 stars (23) | | Customer reviews | 4.2 4.2 out of 5 stars (23) | | Date First Available | 5 September 2024 | | Global Trade Identification Number | 00818625022754 | | Item Dimensions | 31 x 51 x 138 millimeters | | Item Form | Gel | | Item Type Name | Retinal Serum | | Item Volume | 7.62 Milliliters | | Item model number | P08843 | | Manufacturer | PANGAEA | | Manufacturer | PANGAEA | | Manufacturer Part Number | P08843 | | Material Features | Antioxidant | | Material Type Free | Alcohol Free, Fragrance Free, No Synthetic Colours, Paraben Free, Vegan | | Model Number | P08843 | | Number of Items | 1 | | Other Special Features of the Product | Backed by Science, Delivers Radiant, Youthful Skin, Dermatologist Recommended, Minimises Signs of Ageing, Professional Results | | Product Benefits | Radiant Skin | | Product Dimensions | 3.1 x 5.1 x 13.8 cm; 50 g | | Recommended Uses For Product | Wrinkles | | Skin Type | Normal | | Special Ingredients | Retinaldehyde | | Specific Uses For Product | Dark Spots, Wrinkles | | UPC | 818625022754 | | Unit Count | 30.0 Milliliters | ## Product Details - **Age range (description):** Adult - **Brand:** Medik8 - **Item dimensions L x W x H:** 31 x 51 x 138 millimeters - **Item volume:** 7.62 Milliliters ## Images ![Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml - Image 1](https://m.media-amazon.com/images/I/61o1Xs9h6mL.jpg) ![Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml - Image 2](https://m.media-amazon.com/images/I/715U9XF6pAL.jpg) ![Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml - Image 3](https://m.media-amazon.com/images/I/81L7B-yhoeL.jpg) ![Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml - Image 4](https://m.media-amazon.com/images/I/81XcIFP9W+L.jpg) ![Medik8 Crystal Retinal 20 - Age-Defying Retinal Night Serum - Improves Wrinkles & Skin Firmness- 0.2% Retinal Strength - 11x Faster than Retinol - For Highly Experienced Vitamin A Users - 30ml - Image 5](https://m.media-amazon.com/images/I/71sCWDvzXCL.jpg) ## Available Options This product comes in different **Pattern** options. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by J***S on 21 January 2026* I can't speak highly enough of Medik8's retinol range - it's kind enough for my sensitive skin, the cream formula minimises the risk of it degrading, and the different strengths mean you can adjust daily based on what your skin is doing.
