Overtime, your skin’s ability to renew itself slows. Skin loses its elasticity and wrinkles become more evident. As your skin cell turnover continues to slow, you may notice that wrinkles become deeper and more settled. RoC® Retinol Correxion® Deep Wrinkle Filler is an intensive, anti-wrinkle formula that immediately begins to fill creases and re-plump skin. With daily use, it continues to improve the look of skin so that even deep wrinkles appear diminished in as little as four weeks. The result – re-plumped, beautiful skin. Use in the AM and​/​or PM. Gently dab a small amount of product onto wrinkles. Begin applying this product every other night and then gradually increase frequency. Apply a sunscreen of SPF 15 or higher during the day while using this product.
