Reveal a more youthful appearance with this lightweight Intelligent Retinol (vitamin A) serum. Designed to complement skin's nightly regenerative cycle, Retinol 3TR™ resurfaces while you sleep to rejuvenate skin and restore radiance. Hailed as the most effective ingredient in anti-ageing, vitamin A improves skin texture, minimises the appearance of fine lines and wrinkles and balances uneven skin tone. Retinol also helps to decongest pores and regulate sebum production for a clearer looking complexion. Formulated with Time Release Technology, retinol is delivered gradually into the deeper layers of the skin throughout the night to ensure maximum results without overwhelming or irritating skin. That's why we consider all our retinol products: "intelligent retinol". Formulated with 0.3% retinol and supported by vitamin E for enhanced stability, this fast-absorbing serum is perfect for those new to vitamin A, or to upgrade from Night Ritual Vitamin A™.
