Why This Beats Standard Retinol

Retinaldehyde is one conversion step closer to retinoic acid (the active form of vitamin A) than retinol—meaning it works 11x faster without a prescription. But most retinals degrade rapidly once opened, losing potency within weeks. Medik8's patented crystal encapsulation and carrot seed oil complex solve this, delivering stable, effective retinal from the first pump to the last. Add airless packaging that prevents oxidation, and you have the most reliable vitamin A results outside a dermatologist's office.

Best For

Very sensitive skin types, rosacea-prone skin, first-time vitamin A users who've experienced irritation with other retinoids, those seeking the gentlest introduction to clinical-strength results.

FAQS

Is Crystal Retinal 1 strong enough to see results? +

Absolutely. Retinaldehyde works 11x faster than retinol regardless of concentration. Crystal Retinal 1 delivers visible improvement in texture, tone and fine lines—just at the gentlest pace for sensitive skin.

Can I use Crystal Retinal 1 if I have rosacea? +

Crystal Retinal 1 is the most suitable strength for rosacea-prone skin. Always patch test first and introduce gradually. If you experience persistent redness, consult your dermatologist.

How long before I can move up to Crystal Retinal 3? +

Complete at least one full tube (approximately 8-12 weeks of nightly use) before considering the next strength. Your skin needs time to fully adapt.

Why choose retinal over retinol? +

Retinaldehyde converts to retinoic acid in just one step versus two for retinol—meaning 11x faster results. Medik8's crystal encapsulation also makes it remarkably gentle compared to standard retinals.

Can I use Crystal Retinal 1 around my eyes? +

The eye area is too delicate for Crystal Retinal. Use Crystal Retinal Ceramide Eye instead—specifically formulated for this sensitive zone.

Do I need to use SPF the next morning? +

Yes, always. Vitamin A increases photosensitivity. Apply SPF 30+ every morning, even on cloudy days.
