✓ Intensive 0.2% Strength | ✓ 11x Faster Than Retinol | ✓ Double the Power of Crystal Retinal 10

Medik8 Crystal Retinal 20 delivers intensive anti-ageing power for experienced vitamin A users. At 0.2% retinaldehyde—double the concentration of Crystal Retinal 10—this formula pushes visible results further while Medik8's patented stability system maintains the comfort you expect.

The crystal encapsulation technology is essential at this strength, protecting the potent retinal molecule and releasing it gradually for maximum effectiveness without overwhelming the skin. Combined with hydrating hyaluronic acid and nourishing vitamin E, your complexion stays comfortable while transformation accelerates.

Note: The higher retinal concentration gives Crystal Retinal 20 a peachy tone that may temporarily tint skin or transfer to bedding. Allow full absorption before contact with fabrics; any transfer washes out easily.

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

Experienced users who've completed at least one tube of Crystal Retinal 10, those seeking more intensive visible results, skin that tolerates high-strength vitamin A without irritation.

FAQS

Who should use Crystal Retinal 20? +

Experienced vitamin A users who've completed at least one tube of Crystal Retinal 10 and want more intensive results. Your skin must be fully adapted to retinaldehyde with no irritation at Crystal Retinal 10.

Why is Crystal Retinal 20 peach-coloured? +

The higher concentration of retinaldehyde combined with natural plant extracts creates Crystal Retinal 20's distinctive peachy tone. This is completely normal and indicates potency.

Will Crystal Retinal 20 stain my skin or pillows? +

Crystal Retinal 20 may leave a temporary peachy tint on skin (fades by morning) and can transfer to light fabrics. Allow full absorption, apply moisturiser on top, and wash any affected bedding at 30°C—sunlight helps fade any marks.

Is there any difference between Crystal Retinal 20 and Crystal Retinal 24 besides strength? +

Both use the same base formula. Crystal Retinal 24 contains 0.24% retinaldehyde versus Crystal Retinal 20's 0.2%—a meaningful increase for expert users seeking maximum results.

Can I jump straight to Crystal Retinal 20 from a different brand's retinol? +

Not recommended. Even experienced retinol users should start lower on the Crystal Retinal ladder (typically Crystal Retinal 3 or Crystal Retinal 6) as retinaldehyde works differently than retinol.

How long should I use Crystal Retinal 20 before trying Crystal Retinal 24? +

Complete at least one full tube (8-12 weeks of nightly use) with no sensitivity before considering Crystal Retinal 24.
