  • How It Works

    Retinol, also known as vitamin A, is often referred to as the gold standard in anti-ageing skincare. When applied to the skin, it is converted to retinoic acid, the molecule that signals skin cells to produce proteins such as collagen. This increase in retinoic acid both boosts and preserves collagen levels within the skin for a plump, youthful complexion.

    1. Vitamin A can also boost the regenerative cycle of skin cells and hinder the formation of excess melanin to leave skin looking smooth and even-toned.

    2. Time Release Technology distributes the intelligent formula continuously throughout the night, slowing down vitamin A absorption for reduced irritation. 

    3. Climbazole is able to block the enzyme which breaks down retinoic acid, leaving a reservoir of vitamin A for the skin to use up. This means climbazole strives for maximum vitamin A results, while keeping any irritation potential to a minimum.

    4. Vitamin A is used in combination with vitamin E, an oil-soluble antioxidant that helps to protect delicate skin from external free radical damage, while stabilising vitamin A for a highly potent, long-lasting formula.

  • How To Use
    1. After cleansing in the evening, massage 4 drops of Intelligent retinol across the face, neck and décolletage.

    2. Follow with your regular Medik8 moisturiser or facial oil.

    3. Retinol application should be phased in gradually. Use twice a week for the first 2 weeks, every other night for the next 2 weeks, then every night. Consult a doctor if breastfeeding or pregnant.

    4. Patch testing prior to use is advised. Refer to for an in-depth guide to patch testing.

  • The Science Behind

    “Vitamin A is notorious for causing irritation. When too much retinol is delivered to the skin cells too quickly, an overwhelming spike in levels of vitamin A can cause redness and flaking. As the experts in vitamin A, Medik8 uses the most advanced ‘Time Release’ delivery system to slowly release vitamin A into the skin; reducing irritation and providing an exceptionally stable formula.”
