Choosing Safe and Effective Sunscreens: A Guide to Non-Toxic Sun Protection
Summer is here, and with it comes increased sun exposure. While sunlight offers benefits like improved mood and vitamin D production, excessive sun can be harmful. Finding a safe and effective sunscreen is crucial for protecting your skin. Not all sunscreens are created equal; chemical sunscreens, such as those containing oxybenzone, may disrupt hormones. Mineral sunscreens, using zinc oxide or titanium dioxide, are generally considered safer.
Natural sunscreen options often incorporate ingredients like coconut oil, shea butter, and various seed oils. These provide some level of sun protection and skin benefits, but their SPF is often lower than conventional sunscreens. When choosing natural options, ensure the zinc oxide is non-nano-sized to minimize potential risks. Broad-spectrum sunscreens are essential, protecting against both UVA (aging, wrinkles) and UVB (sunburns) rays.
To choose a safer sunscreen, consider these tips:
- Avoid sprays and loose powders: These pose inhalation risks and may lead to uneven application.
- Don't rely solely on high SPF: SPF primarily protects against UVB rays. High SPF might encourage excessive sun exposure. Aim for SPF 15-50+ and reapply frequently. Zinc oxide and titanium dioxide offer better UVA protection.
- Avoid oxybenzone, homosalate, avobenzone, and retinyl palmitate: These chemicals have potential endocrine-disrupting properties or may increase skin cancer risk.
- Avoid combination sunscreen/bug repellent products: This increases the absorption of repellent ingredients.
- Avoid sunscreen towelettes and tanning oils: These may not provide sufficient protection or promote risky sun exposure.
Remember, shade, hats, and clothing provide the best sun protection. Sunscreen should be used in conjunction with these methods. Consult resources like the Campaign for Safer Cosmetics, Environmental Working Group, and Made Safe for more information on choosing safer sunscreens.
