Crystal Retinal®

Skincare

€53,50

Medik8's nightly vitamin A serum, using retinaldehyde rather than retinol. It comes in progressive strengths from 1 to 24, so you start where your skin is and move up a rung at a time. Nights only, sunscreen every morning after.

Strength: Crystal Retinal 1
Ingredients
  • Retinaldehyde — a next-generation form of vitamin A that converts to retinoic acid faster than standard retinol, targeting fine lines, hyperpigmentation, texture and firmness.
  • Hyaluronic acid — draws moisture into the upper layers of the skin, leaving the complexion hydrated and supple.
  • Vitamin E — an antioxidant that helps protect against free-radical damage.
  • Glycerin — a humectant that traps moisture in the skin to keep it comfortable.

How to use

For evening use only. Always follow with sunscreen the next morning.

  • New users: apply twice a week for two weeks.
  • Then every other night for two weeks.
  • Then nightly, once skin has built tolerance.
  • Apply 2 pumps after cleansing, allow to absorb, then follow with a moisturiser.

FAQ

What strength should I start with?
Begin with the lowest strength your skin tolerates, such as Crystal Retinal 1 for sensitive or first-time users, and build up over time.
Can I use it in the morning?
No, it's designed for evening use only. Always wear sunscreen the following morning.
How long until I see results?
Retinaldehyde converts to retinoic acid faster than retinol, but skin still needs time to adjust — introduce it gradually as described in the application steps.
Can I use it with other actives?
Introduce new actives one at a time and give skin time to adjust before combining retinaldehyde with other exfoliating ingredients.

Vitamin A, without the wait.

Medik8's night-time vitamin A serum, formulated with retinaldehyde rather than retinol. Retinaldehyde converts to retinoic acid in fewer steps than retinol, so it works faster on the look of fine lines, dark spots, congestion and firmness.

It comes in progressive strengths, from Crystal Retinal 1 for first-time or sensitive users through to higher strengths for experienced retinoid users, so skin can build tolerance a rung at a time.
