Fight signs of ageing with the Murad Retinol Youth Renewal Serum. This fast-absorbing, breakthrough formula works to minimise the appearance of fine lines and wrinkles. Powered by Retinol Tri-Active Technology (a fast-acting Retinoid, a time-released Retinol and a Retinol booster), the lightweight serum delivers a firming effect to smoothen and refine skin, whilst Hyaluronic Spheres provide long-lasting hydration for a radiant glow. Swertia Flower Extract increases resilience to reveal a luminous, youthful-looking complexion. All ages and sensitive skin welcome, this serum helps minimise the signs of ageing you can see, and the ones you can't see yet. It delivers an instant dose of retinol and a dose of retinol over time to minimise irritation and prolong benefits. With up to 250% more renewing power than traditional retinol with Retinol Tri-Active Technology, real results are seen in as little as 2 weeks: 93% saw a reduction in lines and wrinkles, 98% noticed smoother skin, and 85% saw more radiant skin. Murad is a PETA certified cruelty-free brand.
