The Medik8 Crystal Retinal 20 is engineered for advanced users seeking maximum age-defying benefits. Its 0.2% retinaldehyde concentration works to rapidly accelerate skin cell turnover, visibly reducing the appearance of fine lines and wrinkles, and improving skin firmness and radiance. Users can expect a more rejuvenated, smoother, and brighter complexion with consistent use. This serum is especially effective for addressing signs of aging that have become more pronounced.
For optimal results, apply two pumps to the face and neck in the evening after cleansing. Allow the serum to absorb fully before following with a rich moisturizer like Medik8 Advanced Night Restore. It's crucial to follow the gradual phasing-in schedule, even if you're upgrading from Crystal Retinal 10, to allow your skin to adapt to the higher concentration. Remember, daily morning sunscreen is non-negotiable when using this product, as vitamin A increases skin's sensitivity to the sun. Consistent nightly application, after acclimation, is key to unlocking the full potential of this powerful serum, typically leading to visible improvements in skin texture and tone within weeks, with more profound anti-aging benefits over several months.
Evening Routine: Use only in the evening after thoroughly cleansing your face and neck.
Application: Dispense two pumps of Crystal Retinal 20 onto your fingertips and gently massage evenly over your face and neck.
Absorption & Follow-up: Allow the serum to absorb completely before applying a rich moisturizer. Medik8's Advanced Night Restore is recommended for synergistic benefits.
Phasing-In (Crucial): Even if you've used Crystal Retinal 10, phase in Crystal Retinal 20 gradually.
Weeks 1-2: Apply twice a week.
Weeks 3-4: Apply every other night.
After Week 4: Apply every night, or as tolerated.
Patch Testing: Always perform a patch test prior to full facial application, especially for new users or those moving to a higher strength. Refer to medik8.co/patch for detailed patch testing instructions.
Sun Protection: Always apply a high-factor broad-spectrum sunscreen every morning while using any vitamin A product.
Crystal Retinal 20 is part of the Medik8 Crystal Retinal series and integrates well with other Medik8 products, particularly those in the Wrinkle Repair guide and post-vitamin A moisturizers like Advanced Night Restore. It is designed to be the primary active anti-aging serum in your evening routine.
Store the serum in a cool, dark place away from direct sunlight and extreme temperatures to maintain its efficacy.
Ensure the cap is tightly sealed after each use to prevent oxidation.
Each tube provides up to 3 months of supply when used daily after the initial phasing-in period.
