How to Use

First-time use: If you're new to Crystal Retinal we recommend a patch test at least 24 hours before first use. Phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night.

  1. After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb.
  2. Follow with a moisturiser. We recommend Advanced Night Restore which is engineered to be used after vitamin A (retinoids).
  3. Always use a sunscreen the next morning after using vitamin A. We recommend Advanced Day Ultimate Protect.

Note: We recommend using at least 1 tube of your current Crystal Retinal strength before moving up the ladder to the next strength.

Key Ingredients

  • Retinaldehyde – Proven to work up to 11 times faster than standard retinol,[2] retinaldehyde (retinal for short) is a revolutionary form of vitamin A that effectively targets the appearance of fine lines and wrinkles, hyperpigmentation, uneven skin texture and loss of firmness - without irritation.
  • Hyaluronic Acid – With the ability to attract and retain more than 1,000 times its own weight in water, hyaluronic acid draws moisture into the upper layers of the skin; leaving the complexion hydrated and visibly supple.
  • Vitamin E – A powerful antioxidant that provides additional antioxidant protection against the ageing effects of free radicals.
  • Glycerin – A natural humectant which traps moisture within the skin to leave it hydrated and comfortable.

Before you buy

Using this with microneedling

Microneedling opens channels for a few hours. What you apply afterwards, and when, changes the result.
