Although a few studies have raised questions about the safety of oxybenzone and retinyl palmitate, two ingredients found in some sunscreens, they are entirely avoidable if you read labels. So, what are potential concerns about those two components? Oxybenzone has been shown to cause hormone disruption in studies of cancer cells (however, a study on its effect when applied to skin did not show any statistically significant change in hormone levels). Retinyl palmitate has been linked to skin cancer when applied topically in very large doses to mice (however, the species of mice used in the study were far more susceptible to skin cancer than humans, and there aren't any human studies showing the ingredient causes cancer, according to Steven Q.Wang, director of Dermatologic Surgery and dermatology at Memorial Sloan-Kettering Cancer Center in Basking Ridge, NJ).
