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.
