This was the first of many collaborations with dermatologists to provide them with safe and effective products for their patients. Dr. Lissarrague believed in innovative skincare solutions, based on science, to help women look and feel their best at every age. SCIENTIFICALLY CRAFTED & CLINICALLY PROVEN: Every RoC product is scientifically crafted and tested to ensure the highest quality. Our lead scientists will investigate up to 1,000 ingredients before arriving at the ideal formula. Once the formula is crafted, it goes through rigorous testing to determine its safety and effectiveness. In fact, RoC is one of the only manufacturers to conduct a one-year clinical study proving that the benefits of RoC RETINOL do not plateau — it actually becomes more effective with continued use. Why are we committed to this rigorous approach? Because of our commitment to you. We deliver on our promises - visible results and a lifetime of healthier skin.Our innovative products are recognized by industry leaders, dermatologists and beauty editors, year after year, for their best-in-class effectiveness. We believe it\'s our innovative, scientific approach to skincare that has set the bar for our award-winning products and continues to raise it. We may have developed the first hypoallergenic product, the first sunscreen and the first over-the-counter Retinol, but that\'s just the beginning. We continue to research, reinvent, and innovate to develop new formulas. By building on our past and looking to the future, we\'re committed to helping you be your best at every age.
