In the often murky waters of the clean beauty industry—where greenwashing and empty promises are commonplace—one founder is demanding radical transparency. Sarah Miller, a media powerhouse of the PR world and longtime CEO of Axis Entertainment, did not build EthoSun in a boardroom. The medical-grade, reef-safe sun and skincare line was born from something far more personal: her own fight for survival following multiple brain surgeries. Grounded in science and uncompromising honesty, EthoSun asks a fundamental question: what is truly safe for both skin and the planet?
That life-altering experience reshaped Miller’s priorities and deepened her focus on human health and environmental responsibility. It led to the creation of her global nonprofit, World Health Initiatives, and ultimately to a troubling realization at the intersection of wellness and environmental harm. While working to protect coastal communities and fragile reef systems, Miller saw that many chemical sunscreens marketed as “safe” were contributing to coral destruction and exposing users to carcinogenic ingredients. EthoSun emerged as the answer—a brand rooted in medical integrity, scientific rigor, and the guiding principle Skin First. Planet Always.
This is the story of how Sarah Miller transformed a personal health crisis into a global movement for ethical, science-backed beauty—challenging an industry to look beyond the label and setting a new, uncompromising standard for protection and purity.
From Illness to Initiative: A CEO’s Pivot to Healthcare Advocacy
Miller’s perspective fundamentally shifted after undergoing multiple brain surgeries to remove a tumor. While she is now healthy, the experience forced her to re-examine life’s priorities, focusing on what she calls the inherent human right to health and clean resources. “I am so grateful I survived that time in my life and that it changed me,” Miller shared. “I realized how important healthcare is, don’t take anything for granted; not what you ingest nor what you put on your skin.”
This profound realization led to the creation of her nonprofit, World Health Initiatives, which focuses on providing clean drinking water and medical access to indigenous tribes worldwide, including in Peru, Fiji, and Roatan. The nonprofit’s work soon exposed a critical, unaddressed problem in tropical climates: the need for effective, non-toxic sun protection.“I created EthoSun because I refused to sacrifice skin and beauty for the planet we walk on and the oceans we swim in, and I refused to sacrifice the planet and our oceans for skin and beauty. While in Roatán (an island on the second-largest reef bed in the world), I realized I wanted to leave a handprint, not just a footprint. I wanted to do better,” Miller said.
She recognized that the very products people were using to “protect” themselves from the sun were harming them and the planet, ultimately leading to greater instability for the communities she served. The brand, she insisted, “wasn’t created in a boardroom, it wasn’t glamorous, there was no fanfare,” but rather the essential “story behind the story” of what was needed in the clean beauty space.
The Zero-Tolerance Standard: Challenging Greenwashing with Science
Miller is fiercely critical of the industry’s widespread use of “green washing” and “fake marketing,” which she believes hides a lack of accountability and the use of dangerous ingredients. This drive for radical transparency became the cornerstone of EthoSun’s formulation strategy. Miller noted that chemicals found in conventional sunscreens are contributing to the global destruction of coral reefs, resulting in catastrophic environmental losses. In the Bahamas alone, reef degradation has led to an estimated $33 million decline in tourism revenue and left approximately 13,000 people unemployed.
While some smaller companies offer “reef safe” zinc-based products, Miller argued that they often fail to meet consumer expectations, using cheap fillers that irritate the skin or lack the luxury feel of conventional brands. Miller’s team, which includes their Head of Science for Product Development and a Chief Medical Director, ensures every product is rooted in medical-grade standards.
“EthoSun uses zero toxic chemicals. All of our products are non-nano zinc, with 99% active ingredients, no fillers, and no additives,” Miller said. Their commitment to integrity was tested during the manufacturing process. Miller described an incident with a potential formulator who was not honest about their process and credentials. She immediately walked away. “We needed to believe in our chemist,” she explained. “We weren’t going to compromise.” This ethical grounding is why Miller encourages consumers to “look beyond the label,” to understand who truly owns and manufactures their products.
Product Innovation: Nurturing Skin and Planet
The EthoSun product line is designed to prove that conscious-driven luxury can be clean. The formulas combine cutting-edge science with powerful natural ingredients selected for their hydrating and protective properties. These proprietary, hero ingredients include Squalane, Big Kelp Algae, and local favorites like Prickly Pear (noted for its super-hydrating effects near her home in Scottsdale, Arizona).
EthoSun’s flagship Daily Mineral SPF 50+ for Face won the 2025 Best in Beauty award for its breakthrough formula. The product is renowned among users for its non-white cast, sweat and water-resistant properties, and its unique ability to serve as a superior makeup base. “A lot of women do not use primers with our products,” Miller revealed. “Their makeup sets beautifully over our sunscreen, and they know they have protection.”
Beyond core sunscreens, Miller’s innovation extends to its line of Zinc Beauty Bars, designed to deliver the calming, restorative properties of zinc to everyday cleansing routines. These bars, available in varieties such as Shea Butter (for extra moisture) and Goat Milk (for nourishing lipids), are effective at soothing irritation, razor burn, and sensitive skin.
Miller made a surprising, yet compelling, analogy for the bars’ purity:
“Zinc has long been used in medical and dermatological care for its ability to calm irritation and support the skin barrier,” Miller said. “At EthoSun, we use non-nano zinc because it delivers that same clinically trusted protection in a formulation that is gentle enough for the face and effective enough for daily use without compromise.”
Scaling with Strategic Purpose: A Movement, Not a Trend
Looking ahead, Miller’s primary focus is not on rapid, unchecked expansion but on strategic and ethical scaling in 2026. This caution is dictated by the high cost of the non-nano zinc and medical-grade ingredients used in the formulas. “We don’t want to cut our products and put cheap fillers in them just to lower our cost to have greater expansion,” Miller stated. “We want to keep ourselves exclusive, we want to keep true to the core of what we believe in.”
The journey of EthoSun–from a personal health scare and a nonprofit’s mission to a globally recognized clean beauty movement–underscores Sarah Miller’s unwavering commitment to integrity over profit. She has positioned herself as an industry leader, “willing to stand in the fire” where oversight is scarce and accountability is often avoided, fighting for genuine transparency in product development and clean marketing.
By routing every decision in science and medical expertise, Miller is proving that consumers should not have to compromise their skin health or the planet’s well-being. Every purchase fuels the foundation, ensuring that the brand’s promise extends far beyond the label and actively supports reef restoration and humanitarian efforts.
This intentional approach means the company is carefully targeting distribution, focusing on Islands sitting along our reef zones, cruise lines, resorts, and luxury spas–channels where the demand for a genuinely clean, high-performance product is highest–especially those that are now banning chemically based sunscreens like island ports and popular tourist destinations.
Ultimately, Miller sees EthoSun as bigger than herself. By supporting the brand’s sustainability efforts with every purchase, consumers can be part of the solution.
“We didn’t just create a brand, we created a clean beauty movement,” Miller concluded. “It’s our story, my love letter to the planet, and everyone who chooses EthoSun becomes a part of that story.”
