The Sunscreen Conundrum: What You Need to Know
The Importance of Sunscreen
Feeling the warmth of summer sun on your skin is a great feeling, but it’s essential to apply sunscreen to protect yourself from skin cancer. However, concerns have been raised about the potential risks of sunscreen ingredients leading to other types of cancer. In this article, we’ll explore the world of sunscreen, its ingredients, and what you can do to stay safe while enjoying the sun.
What’s in Sunscreen?
Sunscreen contains active ingredients that provide broad-spectrum protection against UVA and UVB rays. There are two main types of sunscreen: physical and chemical. Physical sunscreens, also known as mineral-based sunscreens, contain zinc oxide and titanium dioxide, which act as a physical barrier between your skin and the sun. Chemical sunscreens, on the other hand, contain a mix of active ingredients that absorb UV rays.
Should You Be Concerned About Your Sunscreen?
The answer depends on the type of sunscreen you’re using. Most concerns surrounding sunscreen ingredients are about the active ingredients in chemical sunscreens. A 2020 study by the U.S. Food and Drug Administration (FDA) found that six chemical sunscreen ingredients were systemically absorbed into the body. This raises concerns about the potential health risks associated with long-term use.
Hormone Disruptors and Carcinogens
Some chemical sunscreen ingredients have been linked to hormone disruption and carcinogenicity. Oxybenzone, for example, has been shown to disrupt the endocrine system and may increase the risk of breast cancer and endometriosis. Octinoxate, another ingredient, has been linked to skin allergies and immunotoxicity. Some chemical sunscreens have also been found to be contaminated with benzene, a known carcinogen.
What Can You Do to Stay Safe?
To minimize your exposure to potentially harmful ingredients, consider using broad-spectrum mineral-based sunscreens that contain only zinc oxide and titanium dioxide. Look for cream-based lotions or sunscreen sticks, as aerosol sunscreens can pose health risks if inhaled. Avoid sunscreens with fragrances, as this term can hide a mixture of potentially harmful chemicals. Sunscreens made for young children are generally safer, as they are formulated with higher safety standards.
The FDA’s Stance
The FDA has requested data from sunscreen manufacturers to determine the safety of their ingredients. However, none of the manufacturers have provided the necessary information. The FDA emphasizes the importance of determining the safety of these ingredients and encourages consumers to be cautious.
Conclusion
While there are concerns about the ingredients in sunscreen, the American Academy of Dermatology emphasizes the importance of wearing sunscreen to protect against skin cancer. The FDA, EWG, and AAD all encourage people to wear sunscreen whenever they are outside. By understanding the ingredients in your sunscreen and taking steps to minimize your exposure to potentially harmful chemicals, you can enjoy the sun while staying safe.
