As Bethany McDaniel’s controversial billboard proclaimed “The sun isn’t poison, but your sunscreen is,” the Primally Pure founder ignited a fierce debate about chemical sunscreens that has both dermatologists and natural health advocates weighing in on what truly constitutes sun safety.
At a Glance
- Primally Pure founder Bethany McDaniel promotes zinc oxide-based sunscreens as safer alternatives to chemical-laden options
- Chemical sunscreens contain ingredients like oxybenzone that may disrupt hormones and have been banned in some regions
- Despite increased sunscreen use, skin cancer rates continue to rise, raising questions about effectiveness
- Moderate sun exposure offers health benefits including vitamin D synthesis, improved mood, and better sleep
- Dermatologists maintain that sun exposure remains a greater risk than properly formulated sunscreens
The Sunscreen Controversy
Bethany McDaniel, founder of natural skincare company Primally Pure, has sparked controversy with her bold marketing campaign challenging conventional wisdom about sun protection. Her company’s billboard stating “The sun isn’t poison, but your sunscreen is” represents a growing movement questioning the safety of traditional chemical sunscreens. McDaniel’s advocacy centers on creating products that protect skin without potentially harmful ingredients, directly challenging what she sees as fear-based messaging from the conventional sunscreen industry.
This stance has created significant division among health professionals. While McDaniel questions why her message is considered controversial, dermatologists maintain that sun exposure remains the primary risk factor for skin cancer. The debate highlights a fundamental tension between those promoting natural alternatives and medical professionals concerned about rising skin cancer rates, which affect more than one in five Americans during their lifetime.
Chemical Concerns in Traditional Sunscreens
Growing research suggests certain chemical sunscreen ingredients may pose health risks. Oxybenzone, found in 96% of the population according to some studies, has raised particular concern. This common sunscreen chemical can be absorbed through the skin into the bloodstream and has been detected in breast milk, urine, and amniotic fluid. Studies indicate it may disrupt hormonal systems, potentially increasing risks of endometriosis and uterine fibroids in women and affecting male reproductive health.
Environmental impacts have also prompted regulatory action. Hawaii has banned oxybenzone-containing sunscreens due to their damaging effects on coral reefs, and the European Commission has taken steps to restrict this ingredient. Other chemicals of concern include retinyl palmitate, which some research suggests may accelerate skin damage when exposed to sunlight, and benzene, a carcinogen that has been detected in some sunscreen formulations as a contaminant.
The Case for Mineral Alternatives
Mineral sunscreens containing zinc oxide and titanium dioxide have emerged as the primary alternatives to chemical formulas. These ingredients work by creating a physical barrier on the skin that reflects and scatters UV rays rather than absorbing them like chemical filters. The FDA has designated these mineral options as “generally recognized as safe and effective,” making them the preferred choice for those concerned about chemical absorption and environmental impact.
Non-nano zinc oxide has become particularly popular in natural sunscreen formulations as it offers broad-spectrum protection without the concerns about particle size that might allow absorption into the bloodstream. Companies like Primally Pure have focused on combining these mineral filters with nourishing ingredients that support skin health while providing protection. However, mineral options often have drawbacks including white residue, difficulty in application, and sometimes lower SPF ratings than their chemical counterparts.
Finding Balance in Sun Safety
The nuanced approach that McDaniel and other natural health advocates promote recognizes both the risks and benefits of sun exposure. Regular, moderate sun exposure contributes to vitamin D production, which supports immune function, bone health, and mood regulation. Additional benefits include improved sleep quality, lower blood pressure, and enhanced mitochondrial function. These positive effects stand in stark contrast to the sun-avoidance messaging that has dominated public health campaigns.
A balanced approach might include gradual sun exposure during safer hours (before 10 am and after 4 pm), wearing protective clothing, seeking shade during peak UV hours, and using mineral-based sunscreens when extended exposure is unavoidable. This strategy allows individuals to benefit from the sun’s positive effects while minimizing damage that could lead to premature aging or skin cancer. The conversation McDaniel has initiated encourages consumers to make informed choices rather than relying solely on industry messaging from either extreme.
