Elevate your skincare game with Medik8 Crystal Retinal 6, a next-generation retinaldehyde serum delivering clinical-grade results without the downtime. Designed for experienced retinol users ready to take the next step, this powerful nighttime treatment visibly reduces fine lines, improves skin tone and texture, and restores youthful radiance—fast.
Key Benefits:
-
✨ Reduces fine lines and wrinkles in just 4 weeks
-
💪 Retinaldehyde works up to 11x faster than retinol
-
🌙 Boosts collagen production & cellular turnover overnight
-
💧 Hydrates and strengthens with hyaluronic acid & vitamin E
-
🔬 Clinically proven results, yet gentle enough for nightly use
-
🧴 Silk-like texture melts into the skin without residue
How It Works:
Crystal Retinal 6 uses encapsulated retinaldehyde, a potent vitamin A derivative one step closer to retinoic acid than retinol—providing faster, visible anti-ageing results with less irritation. It actively supports skin regeneration, firms sagging areas, smooths out uneven skin tone, and enhances elasticity. Multi-weight hyaluronic acid locks in hydration across all layers of the skin, while vitamin E supports barrier repair and antioxidant protection.
How to Use:
-
In the evening, after cleansing, apply a small amount of Crystal Retinal 6 to the face and neck.
-
Follow with your moisturiser.
-
Start with 2–3 times a week and gradually increase to nightly use as skin builds tolerance.
Patch testing recommended before full use. Avoid during pregnancy or breastfeeding.
