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

Expert vitamin A users only—must have used at least one full tube of Crystal Retinal 20. Those seeking the most powerful over-the-counter retinal available. Maximum age-defying results for fully adapted skin.

FAQS

How do I know I'm ready for Crystal Retinal 10? +

You should have completed at least one full tube of CR6 using it nightly without irritation. If you're still experiencing sensitivity at CR6, stay at that strength longer

Will I see significantly better results than Crystal Retinal 6? +

Yes—the higher concentration accelerates visible improvement in deeper lines, stubborn pigmentation and firmness. However, the jump from Crystal Retinal 6 to Crystal Retinal 10 is noticeable, so monitor your skin closely.

Do I need to phase in again when moving from Crystal Retinal 6? +

Technically no, but many users prefer a brief adjustment period. Consider using Crystal Retinal 10 every other night for the first week if your skin feels sensitive.

Can I use this around my eyes? +

No—the eye area requires the gentler Crystal Retinal Ceramide Eye formula. Crystal Retinal 10 is too potent for this delicate zone.

Is there anyone who shouldn't move beyond Crystal Retinal 10? +

Some skin types find Crystal Retinal 10 their optimal strength. If you're seeing excellent results and tolerating it well, there's no requirement to move higher. Crystal Retinal 20 and Crystal Retinal 24 are for those specifically seeking more intensive results.

How long will one tube last? +

Using 2 pumps nightly on face and neck, expect 8-12 weeks per 30ml tube depending on application amount.
