Sarah Miller Is Rewriting the Rules of Sun Care With EthoSun

Most sunscreen brands promise protection. Sarah Miller set out to deliver something harder: protection without collateral damage. As the founder and CEO of EthoSun, Miller is building a new category of mineral sun care—one that treats skin health, environmental safety, and product performance as inseparable.

EthoSun entered a crowded, highly regulated market with a clear position. Its formulas rely on medical-grade, non-nano zinc oxide, verified reef-safe ingredients, and nourishing botanicals, eliminating chemical filters that have long raised concerns for both human health and marine ecosystems.

A Brand Born From Accountability

EthoSun’s origin story is not a marketing exercise. It began with Miller confronting an uncomfortable truth: many products designed to protect people were quietly harming coral reefs and ocean life. Rather than settle for incremental improvement, she chose reinvention—creating sun care that is reef-safe by design, not by disclaimer.

The result has been swift validation. Within its first year, EthoSun completed a successful national launch across multiple SKUs, secured retail and distribution pathways through major beauty trade shows, and expanded its investor and advisory board. In 2025, the brand’s Daily Mineral SPF earned the Best in Beauty Award, positioning EthoSun as both a scientific and commercial contender.

Science Without Greenwashing

What distinguishes EthoSun is restraint. The brand avoids inflated claims and ingredient overload, focusing instead on efficacy, transparency, and regulatory credibility. Its zinc formulations have passed aquatic safety trials, reinforcing Miller’s insistence that sustainability must be proven, not implied.

Founder pull-quote: “We didn’t want to create another ‘clean’ product. We wanted to create one that could stand up to medical scrutiny and environmental responsibility at the same time.”

Leadership With Long-Term Intent

Miller brings nearly two decades of experience in media, brand strategy, and global partnerships to EthoSun, but her leadership style is notably disciplined. Growth is pursued alongside governance, sustainability partnerships, and compliance in high-profile destinations where sun care standards are tightening.

In an industry often driven by trends, EthoSun is built for longevity. It reflects a broader shift in women-led entrepreneurship—where values are operationalized, not just voiced.

EthoSun does not frame responsibility as a trade-off. Under Sarah Miller’s direction, it is becoming a competitive advantage—proving that modern sun care can be powerful, luxurious, and accountable, all at once.
