Medik8 Crystal Retinal 24
Introducing the pinnacle of Medik8’s retinoid innovation - Crystal Retinal 24. Designed for expert users, this is the highest strength in the Crystal Retinal range. With 0.24% crystal-encapsulated retinal, it acts 11x faster than standard retinol*, visibly smoothing fine lines, brightening the complexion, and firming the skin. Medik8’s patented stability system ensures potent results, while encapsulation technology minimises irritation, making it suitable for sensitive skin.
Crystal Retinal 24 is ideal for those ready to progress through our unique ladder of 6 retinal strengths (0.01 - 0.24% retinaldehyde). It allows users to achieve powerful, visible results without the irritation often associated with higher concentrations. Developed based on user feedback, this formula offers an accessible yet potent age-defying solution. As Dr. Dendy Engelman, Medik8 Global Ambassador, says: “Crystal Retinal sets a new standard, offering the strongest over-the-counter option available."

Benefits of Using a 0.24% Encapsulated Retinaldehyde Serum
✓ Faster Results:
Retinaldehyde is known for acting 11x faster than standard retinol*, making it a potent choice for those looking to achieve visible skin improvements quickly. The 0.24% concentration allows for rapid skin renewal, visibly reducing the appearance of fine lines, wrinkles, and uneven skin tone. In fact, 90% agree Crystal Retinal 24 is the most powerful anti-ageing product they have ever used.**
*Proven via independent clinical study on the Crystal Retinal ladder tested on 30 participants over 24 weeks.

✓ Patented Retinal Stability:
One-of-a-kind carrot seed oil complex that protects retinal from degradation, for optimal effectiveness in the skin.
✓ Clinically Proven Efficacy:
Targets deep-set wrinkles and loss of firmness, delivering smoother, brighter, firmer-looking skin.
✓ Crystal-Encapsulation Delivery System:
Gradually releases retinal overnight, maximising comfort and minimising irritation.
✓ Minimal Irritation:
The powerful yet fragile retinal molecule is protected by a crystal encapsulation system that works to blanket the retinal, retaining its power and ensuring it’s gently released into the skin throughout the night to minimise potential irritation.
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.
