Vichy LiftActiv Retinol Specialist Deep Wrinkles Serum is a targeted anti-aging treatment containing 0.2% pure retinol. This dermatologically-tested serum is specifically formulated to reduce the appearance of deep wrinkles and help resurface the skin. This 30ml serum features a fragrance-free, hypoallergenic formula that is suitable for sensitive skin. The product comes in a protective packaging designed to maintain the stability and efficacy of the retinol. For best results, it should be applied in the evening to clean, dry skin. As with all retinol products, it's recommended to gradually introduce it into your skincare routine and always use sunscreen during daytime.
