Description
You should be comfortably using Crystal Retinal 10 every night for at least 3 months, or have completed 2 full tubes, before progressing to Crystal Retinal 20.
Medik8 Crystal Retinal™ 20 is the brand’s highest-strength retinaldehyde serum, formulated for advanced vitamin A users seeking powerful, accelerated anti-ageing results. Featuring an ultra-potent 0.2% encapsulated retinaldehyde, it converts into retinoic acid up to 11 times faster than standard retinol, promoting rapid improvements in firmness, texture and clarity.
This next-generation treatment boosts collagen production to reduce the appearance of fine lines and wrinkles, while refining uneven skin texture and helping to clear blemishes thanks to retinal’s natural antibacterial properties.
To maintain comfort at this elevated strength, the formula is infused with hyaluronic acid, glycerin and vitamin E for deep hydration and barrier support. Medik8’s signature crystal-encapsulation time-release technology ensures controlled delivery, minimising irritation without compromising efficacy.
In just four weeks, expect a brighter, smoother, firmer and more youthful-looking complexion.
