Understanding the Sunscreen Debate: Debunking Concerns and Choosing the Right Protection

With the summer season in full swing, it's crucial to prioritize your skin's well-being against harmful sun rays. However, some questions have emerged around the presence of "toxins" in sunscreen. Experts caution against misconceptions, emphasizing that the risks associated with sunscreen are often blown out of proportion and potentially harmful if they discourage the use of SPF altogether. Dr. Samer Jaber, a certified dermatologist at Washington Square Dermatology in New York, explains, "We know that the sun and UV rays accelerate aging, cause sun spots, wrinkles, and increase the risk of skin cancer. Sunscreen plays a significant role in protecting against these effects. Please remember to practice proper sun safety habits when you are outdoors." Skin cancer, particularly melanoma, claims over 8,000 lives each year, according to the Centers for Disease Control and Prevention. Wearing broad-spectrum sunscreen with an SPF of 30 or higher is strongly recommended by the American Academy of Dermatology as one of the best preventive measures against this disease. So, how did sunscreen become the subject of concern? Firstly, it's important to clarify that the term "chemical" sunscreen refers to one of two types: chemical and mineral sunscreens, based on their active ingredients. Dr. Jaber explains that chemical sunscreens work by absorbing UV radiation, while mineral sunscreens act as a barrier, deflecting rays when they come into contact with the skin's surface. Mineral sunscreens typically contain titanium dioxide and zinc oxide, which the Food and Drug Administration classifies as "safe and effective" components. On the other hand, some specific ingredients found in chemical sunscreens, like oxybenzone, have been detected in the body even weeks after use. However, the potential risks associated with these chemicals are still unclear, as more data is needed to determine their safety and efficacy. Though the FDA is continuously reviewing the status of certain chemical sunscreen ingredients, it's worth noting that mineral sunscreens are an alternative for those concerned about potential absorption. According to Dr. Jaber, mineral sunscreens, specifically zinc oxide and titanium dioxide, have not demonstrated significant absorption into the bloodstream that could impact the body. These physical mineral sunscreens are also gentler on sensitive skin and may be a suitable choice for individuals with conditions such as acne, rosacea, or eczema.
