Crystal Retinal 6

Crystal Retinal 6


Uncover radiant, youthful skin with Crystal Retinal 6, a potent overnight serum that can deliver results comparable to clinical-grade vitamin A up to 11x faster than classic forms of retinol. Unlike retinol, which must first be converted to retinaldehyde and then to retinoic acid (vitamin A’s active form) within the skin, Crystal Retinal requires just one conversion to retinoic acid.

This accelerated action rapidly resurfaces the skin while rebuilding collagen to promote a youthful, radiant complexion. Fine lines and wrinkles are visibly reduced, skin texture is left smooth and supple and overall tone is both luminised and clarified.


  • Reduces the appearance of fine lines and wrinkles in just 4 weeks*

    5. Clears the bacteria responsible for blemishes and breakouts

    6. Utilises an innovative crystal encapsulation system that slowly releases retinaldehyde into the skin for minimal irritation

Key Ingredients

*Time-Release Retinaldehyde – A high-performance, encapsulated active that enhances collagen production and cellular regeneration to promote a younger-looking complexion. Proven to work up to 11x faster than standard forms of retinol, this next-generation active provides results comparable to prescription-strength vitamin A while remaining as gentle on the skin as traditional retinols.

*Hyaluronic Acid – With a unique ability to attract and retain more than 1,000x its own weight in water, this moisture-retaining molecule draws water from the air into the skin to provide intense hydration. Naturally occurring in the body, it also cushions skin cells to give an instant plumping effect.

*Vitamin E – This powerful antioxidant targets free radicals to reduce the rate of premature ageing, while boosting the moisture-retention capacity of the skin to promote optimum hydration. Works synergistically with vitamin C to boost overall antioxidant effect.

*Glycerin – As a natural humectant glycerin traps water within the skin to leave it hydrated and comfortable.
