Medik8 Crystal Retinal 24 Night Serum 30ml

Rediscover exceptionally youthful skin with Crystal Retinal 24, Medik8's ultimate pinnacle in Vitamin A innovation. Formulated at an ultra-strength 0.24% concentration of stabilised retinaldehyde, this professional-grade nocturnal serum is specifically engineered for regular and highly experienced retinoid users looking to maximize their advanced age-defying results.

Unmatched in its potency, retinaldehyde (Retinal) works up to 11 times faster than classic retinol, delivering results comparable to clinical-grade Vitamin A while remaining incredibly gentle on the skin. By optimizing the skin's natural overnight regeneration cycle, Crystal Retinal 24 visibly minimises stubborn, deep-set lines, firms loss of elasticity, and resurfaces uneven texture to reveal an undeniably radiant, smooth, and balanced complexion.

How To Use

Important Note: Crystal Retinal 24 is exclusively designed for expert skincare users who have successfully built up a high tolerance to Vitamin A (such as completing multiple tubes of Crystal Retinal 20).

After cleansing in the evening, massage a small, pea-sized amount of Crystal Retinal 24 evenly across the face, neck, and décolletage, strictly avoiding the delicate eye area and lips. Allow to fully absorb before applying your targeted night moisturiser (such as Medik8 Advanced Night Restore).

Phasing In Guide: Application should be phased in gradually to maintain maximum skin comfort. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then increase to every night. Always wear a high-factor sunscreen (SPF) the following morning and for 1 week after usage. Consult a physician if pregnant or breastfeeding.

Key Ingredients

• 0.24% Encapsulated Retinaldehyde: The ultimate form of non-prescription Vitamin A. Encapsulated in a unique crystal delivery system, it is slowly released into the skin over hours to maximize potency while heavily mitigating the risks of irritation.
• Hyaluronic Acid: Formulated to attract and lock in more than 1,000 times its own weight in water, drawing deep moisture into the upper skin layers to ensure a plumped, supple appearance.
• Vitamin E (Tocopheryl Acetate): A lipid-soluble, highly potent antioxidant that neutralises age-accelerating free radicals while working in tandem to permanently stabilise the retinal molecule.
• Glycerin & Squalane: Plant-derived emollients that mimic the skin’s natural protective barrier, sealing in essential hydration and restoring lipid balance.
