Honoring Gayle Brinkenhoff

Every RevitaLash® Cosmetics product carries a story that began with love. In 2006, ophthalmologist Michael Brinkenhoff, M.D., created our original lash conditioner for his beloved wife, Gayle, after treatments for metastatic breast cancer affected her eyelashes. His hope was simple: to help her feel beautiful and more like herself again.

That deeply personal gift marked the beginning of RevitaLash® Cosmetics — and the foundation of a mission that continues today: to empower women and support the fight against breast cancer, in honor of Gayle Brinkenhoff’s legacy.

Remembering Gayle Brinkenhoff: The Heart Behind the Brand

Gayle was outgoing, magnetic, fun, and kind. She was a devoted mother, wife, sister, and friend; Co-Founder of RevitaLash® Cosmetics; and a passionate advocate for women affected by breast cancer. Diagnosed with metastatic breast cancer at age 32, she lived with the disease for 25 years, meeting hardship with courage and an unmistakable joy for life. This year, she would have celebrated her 70th birthday.

During treatment, changes to her hair and eyelashes affected how she felt when she looked in the mirror. Dr. Brinkenhoff drew on his experience as an ophthalmologist to formulate a conditioning serum to help her lashes look healthier and stronger. It worked.

“A joyful spark returned to her eyes, and with it, her confidence returned,” Dr. Brinkenhoff remembers. “It was heartwarming to witness.”

Friends soon noticed the difference, and Gayle recognized that the formula could give others the same boost in confidence. She coined the name RevitaLash, capturing not only the way the product transformed lashes, but also how feeling beautiful on the outside could inspire a renewed inner spirit. From that loving beginning, a global beauty brand was born.

A Life of Meaning, Joy, and Impact

Gayle’s influence reaches far beyond the product she helped inspire. She shaped our company’s name, our values, and our enduring commitment to giving back.

“Gayle was the heart and soul of this brand,” says Dr. Brinkenhoff. “She was a source of courage and compassion — and she inspired our mission to give back.”

Her daughter, Dariel Sidney, our Vice President of Global Philanthropy, remembers how Gayle transformed a profound personal challenge into purpose: “She was able to take a hardship, something that negatively impacted her health, and turn it into something that positively impacted the world. What she started—the spirit of giving that continues to drive our company today—would not have happened had her illness not been there.”

To those who knew her, Gayle’s warmth was just as unforgettable as her strength. Her son Shane Cohn, our Senior Director of New Business Development, recalls: “She was the mom who was everyone’s mom. She was incredibly loving, very fashionable, and she knew how to have fun, no matter the situation. She was the life of the party. Her spirit and energy are missed by many.”

These memories reveal the woman at the center of the RevitaLash® Cosmetics legacy: someone who made people feel seen, welcomed, and encouraged — and whose compassion continues to guide us today.

How We Honor Gayle’s Legacy Every Day

A portion of the proceeds from every RevitaLash® Cosmetics purchase helps fund breast cancer initiatives that support patients and their families today while advancing research for lifesaving therapies tomorrow. This is our Eternally Pink® pledge — our year-round commitment that honors Gayle Brinkenhoff’s courage and strength, and that of women everywhere.

Since 2008, our RevitaLash® Cosmetics community has helped us contribute more than $14 million in donations, investments, and in-kind support to breast cancer initiatives. As we celebrate our 20th anniversary, we’ve set a bold goal: reaching $20 million for the cause.

“From the beginning, Gayle’s dream was that this company would make a difference,” Dr. Brinkenhoff says. “Every dollar represents a story: a patient helped, a family supported, a research breakthrough funded. It’s a living reflection of Gayle’s spirit and of the compassion that built this brand.”

Breast Cancer Research Funding That Carries Gayle’s Name

Some of our most impactful philanthropic initiatives are named for our Co-Founder, further honoring her legacy:

Supporting the next generation of cancer research. Each year, the Gayle Brinkenhoff IGNITE Award supports an emerging cancer researcher at Mass General Brigham. In 2026, we awarded the grant to Dr. Justin Rolando for his research identifying biomarkers in routine blood tests that may help detect cancer earlier and reduce unnecessary biopsies.

Bringing leading minds together. In partnership with City of Hope, RevitaLash® Cosmetics hosts the Annual Gayle Brinkenhoff Breast Cancer Symposium in Los Angeles. For 10 years, the symposium has brought together researchers, clinicians, oncologists, and scientific innovators to share insights, spark new ideas, and build collaborations that accelerate progress in breast cancer research.

Advancing promising breakthroughs. The Gayle Brinkenhoff Excellence in Cancer Research Award helps researchers pursue discoveries with the potential to improve care. In 2026, two grants supported innovative work at City of Hope and the Karmanos Cancer Institute.

At City of Hope, the award is advancing work in Dr. Jeff Perry’s laboratory, where researchers use structural biology and biochemical methods to study DNA repair and genome stability — critical pathways in the development of novel cancer therapies. The goal is to translate those insights into treatments that improve patient outcomes.

At the Karmanos Cancer Institute, the award supports Dr. Asfar Azmi and his team, who are focused on finding better treatment options for certain hard-to-treat cancers driven by a gene mutation known as KRAS.

Celebrating Gayle’s Life and Carrying Her Dream Forward

Honoring Gayle Brinkenhoff means remembering the joy she brought to others, the confidence she inspired, and the compassion she turned into action. Her spirit continues in every RevitaLash® Cosmetics product, every customer who feels more like themselves, and every initiative that brings hope to people affected by breast cancer.

Dr. Brinkenhoff says, “I think Gayle would be incredibly proud. Proud of our success as a company, and most of all, the kindness that this company represents.”

“Her legacy lives in every product we make and every person we’re able to help. That was always her dream — and it remains my great honor to carry it forward.”
