Best for: dry or tight-feeling routines that need a dedicated moisturising step after vitamin A.

7. Medik8 Crystal Retinal 20: best for established advanced routines

Medik8 Crystal Retinal 20 contains 0.2% encapsulated retinaldehyde. Medik8 recommends it for people who have comfortably used Crystal Retinal 10 for an extended period.

Best for: established advanced retinal users. This is not the starting point for a new vitamin A routine.

How to build an anti-ageing routine

1. Morning: cleanse, apply vitamin C, moisturise if needed, then finish with broad-spectrum sunscreen.
2. Evening: cleanse, apply the retinal strength your skin tolerates, then use a moisturiser.
3. Targeted step: add a peptide serum when expression lines are a priority.
4. Progress slowly: move up a retinal strength only after your current level feels comfortable with regular use.

Patch test new active formulas and introduce one change at a time. If you are pregnant, breastfeeding, treating a skin condition or using prescription skincare, ask a qualified health professional before using vitamin A products.

Which Medik8 anti-ageing product should you choose?

Choose Crystal Retinal 3 for the lowest retinal strength in this comparison, Crystal Retinal 6 for the next step, and Crystal Retinal 10 for an advanced routine. Add C-Tetra Advanced in the morning, Liquid Peptides Advanced MP for expression lines, and Advanced Night Restore when your evening routine needs more moisture. Reserve Crystal Retinal 20 for established users who have already used Crystal Retinal 10 comfortably.
