The American Academy of Dermatology (2021) states that skin cancer is the most common cancer in the United States. One in five Americans will develop skin cancer in their lifetime. Protecting our skin from harmful ultraviolet rays is imperative. However, the human body does benefit from a mild to moderate amount of UV radiation.
Initial post: What is the best way to protect your skin from sun-related damage? What are the advantages and disadvantages to sunscreens containing common active ingredients such as oxybenzone, octocrylene, and homosalate? Are there benefits to using mineral sunscreens, such as zinc oxide or titanium dioxide? How effective are natural sunscreens, such as coconut oil or shea butter? If a sunscreen product is not regulated by the FDA, how can you determine if the product’s claims are true?

Chemical Sunscreens:
These absorb UV rays and convert them into heat, releasing it from the skin. Popular ingredients like oxybenzone, octocrylene, and homosalate offer broad-spectrum protection but raise concerns. Some studies suggest potential hormone disruption and environmental harm, particularly to coral reefs.
Advantages:
- Lightweight, non-greasy, comfortable to wear.
- Effective broad-spectrum protection.
- Wide range of options for different skin types.
Disadvantages:
- Potential for skin irritation, especially for sensitive individuals.
- Potential hormone disruption and environmental concerns.
- Some ingredients (oxybenzone) may not be as photostable as mineral sunscreens.
Mineral Sunscreens:
These physical barriers reflect and scatter UV rays away from the skin. Zinc oxide and titanium dioxide are the champions here, creating a white cast that some find less aesthetic.
Advantages:
- Generally considered safe for sensitive skin and babies.
- Photostable, offering reliable protection even with sun exposure.
- Minimal environmental impact.
Disadvantages:
- Thicker consistency, can feel heavy or leave a white cast.
- May not be as effective against shorter wavelength UV rays (UVA1).
- Limited options for oily or acne-prone skin.
Natural Sunscreens:
Coconut oil, shea butter, and other plant-based oils boast natural SPF properties. However, their protective power pales in comparison to chemical or mineral sunscreens. While they may offer minimal protection against UVB rays, they lack broad-spectrum coverage and cannot reliably block UVA rays, the sneaky culprits behind premature aging and cancer.
Advantages:
- Hydrating and nourishing for the skin.
- Natural and often vegan-friendly.
- Pleasant smelling and lightweight.
Disadvantages:
- Minimal to no effective sun protection against harmful UV rays.
- Can lead to a false sense of security, increasing the risk of sunburn and skin damage.
- Not regulated by the FDA, claims may be unreliable.
FDA Regulation and Trust:
Speaking of unreliable claims, remember that a lack of FDA regulation doesn't automatically mean a product is bad. However, it does add a layer of scrutiny. Look for certifications from independent organizations like the Environmental Working Group (EWG) or the Good Housekeeping Institute, which evaluate sunscreens based on safety and effectiveness. Research the brand's reputation and read reviews from real users.

Ultimately, the best sun protection is a multi-pronged approach. Seek shade, wear protective clothing and hats, and choose a sunscreen that suits your skin type and lifestyle. Remember, consistency is key! Reapply sunscreen every two hours, especially after swimming or sweating.
Sun protection is about making informed choices for our skin's health and future. By staying informed, exploring options, and choosing wisely, we can bask in the sunshine safely, embracing its warmth without fearing its sting.
