Full Description 

Experience the ultimate in retinoid science with Medik8's Crystal Retinal 24. As the strongest formula in the Crystal Retinal range, it utilises 0.24% crystal-encapsulated retinal to deliver 11x faster results compared to standard retinol*. This expert-level product visibly improves skin texture, reduces wrinkles, brightens the complexion, and firms the skin. And with Medik8's patented stability system and encapsulation technology, it's gentle enough for even sensitive skin. Discover the transformative power of Crystal Retinal 24 in your skincare routine. 

Medik8 Crystal Retinal 24 is suitable for expert users, oily or resilient skin.

Crystal Retinal 24 is designed for expert users who have built tolerance through the use of lower strengths and are seeking stronger, faster age-defying results. It’s best suited for individuals with oily or resilient skin types and those looking to address advanced signs of ageing. Conversely, lower strengths like Crystal Retinal 1 and Crystal Retinal 3 are better for those new to retinoids or with sensitive skin, offering a more gradual introduction to retinoid benefits. (Advanced vitamin A users only).

Medik8 Crystal Retinal 24 is not suitable for use during pregnancy or when breastfeeding.

How It Works

The 0.24% encapsulated retinaldehyde (retinal) formula in Crystal Retinal 24 is the pinnacle of our retinal range. This advanced serum is designed for expert vitamin A users seeking the most powerful age-defying results without a prescription.

Strength Comparison: 0.24% Retinal vs. Tretinoin: Tretinoin, a prescription-only vitamin A, is known for being up to 20 times stronger than retinol for improving acne, wrinkles, and photoaging but often comes with side effects like redness, peeling, and increased sensitivity. The 0.24% retinaldehyde in Crystal Retinal 24 offers a compelling alternative for those seeking powerful, prescription-level results without the need for a prescription or the associated risks of irritation.

Retinaldehyde is only one conversion step away from retinoic acid (the active form of vitamin A), making it significantly more effective than retinol, which requires two conversion steps. This makes Crystal Retinal 24 an excellent option for users who want to avoid the harsher effects of tretinoin but still desire a strong anti-ageing solution.

Availability of the 0.24% Retinal Formula: Given its potency, Crystal Retinal 24 is primarily recommended for expert vitamin A users who have built up a tolerance to retinoids. It’s available both online and through Medik8 professionals. However, for those new to this strength Medik8 recommends consulting with dermatologists to ensure the right fit for your skin needs, maximising the benefits of this powerful serum.

How does it compare to other high-strength retinal products? Crystal Retinal 24 sets itself apart as one of the most advanced over-the-counter retinaldehyde products on the market. While other brands may offer similar retinal concentrations, Medik8’s Crystal Retinal 24 stands out for its patented retinal stability technology and comprehensive clinical backing, ensuring both efficacy and minimal irritation.

The science behind CR24 (Crystal Retinal 24) represents the pinnacle of retinaldehyde innovation, designed for those advancing their skincare journey. This formula features 0.24% retinaldehyde, a potent form of vitamin A that’s proven to work up to 11x faster than traditional retinol*, delivering ground-breaking visible improvements in skin texture and tone. Medik8's unique crystal encapsulation technology ensures the retinaldehyde remains stable and effective until the last drop, unlike other formulations that may degrade over time. By gradually releasing the active ingredient into the skin over time, this technology minimises potential irritation while maximising benefits, offering a high-strength solution that smooths, brightens, and firms the skin with exceptional precision.

*Proven via independent clinical study on the Crystal Retinal ladder tested on 30 participants over 24 weeks.

The formula is then reinforced with a unique patented stabilisation complex, based on the protective power of carrot seed oil. This ensures the retinal is stabilised and highly effective throughout its entire life cycle - from raw material until it reaches the skin. Finally, the formula and its stability system are enclosed within an airless, aluminium-lined tube which protects against the degrading effects of oxygen, heat and light. The final result? Market-leading retinal stability that delivers results that continue to be effective until the last drop - as validated through an independent HPLC stability study testing Crystal Retinal against other products in the market within accelerated (stress-tested) conditions.

How does Crystal Retinal 24 compare with Crystal Retinal 20? Crystal Retinal 24 (CR24) and Crystal Retinal 20 (CR20) are both powerful retinaldehyde formulations, but they cater to different levels of skincare experience. CR20 contains 0.2% retinaldehyde, ideal for experienced vitamin A users or those new to high-strength vitamin A. In contrast, CR24 features a higher concentration of 0.24% retinaldehyde, offering more intensive results for expert users.

Our unique new ladder of 6 strengths means you can experience continued visible benefits as your skin builds up tolerance. From vitamin A beginners (Crystal Retinal 3) to very experienced users (CR24), there’s a strength for everyone. The increase in strength from CR20 to CR24 provides a more pronounced effect on skin texture, brightness, and firmness. To ensure optimal results and minimise irritation, users should have used at least one tube of CR20 before progressing to CR24. This progression allows the skin to build tolerance, making CR24 suitable for those who have already acclimated to the lower strength and are seeking advanced, age-defying benefits.
