FAST WRINKLE REDUCING POWER – Wrinkle reduction with just 1 tube. Retinaldehyde works up to 11 times faster than classic retinol.
RADIANT, YOUTHFUL SKIN – Delivers remarkable visible improvement in texture, brightness, firmness & clarity. Vitamin A is a key pillar of Medik8’s simple yet effective anti-ageing strategy of using vitamin C followed by sunscreen by day, and vitamin A at night. This is called the CSA philosophy.
PROFESSIONAL-GRADE RESULTS – Our iconic retinaldehyde serum boasts antibacterial properties to help target blemish-causing bacteria for visibly clarified skin. Our formula features key ingredients: Hyaluronic Acid, Vitamin E and Glycerin.
HOW TO USE – Step 1: After cleansing in the evening, apply 2 pumps of Crystal Retinal to the face and neck. Allow to absorb then follow with a moisturiser. Step 2: For new users of Crystal Retinal, phase application in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night.
PROGRESSIVE STRENGTHS – Our unique ladder of 5 progressive strengths (0.01 – 0.2% retinaldehyde) means you can keep experiencing ever-improving benefits that tackle the most stubborn fine lines, wrinkles and dark spots.
