For many parents, some of the most important health lessons happen in the middle of everyday life.
A reminder to put on sunscreen before heading to camp. Encouraging children to drink more water during a busy summer day. Helping kids understand why healthy habits matter long before they can fully appreciate the consequences of neglecting them.
For Greenwich moms and entrepreneurs Sabrina Chateauvert and Camila Guerrero Suasnavas, those seemingly small moments became the inspiration behind Serein Wellness Co., a growing wellness company built on a simple but powerful belief: prevention should be approachable, engaging, and accessible for families.
As co-founders, the pair are combining healthcare expertise, business acumen, and firsthand parenting experience to create products that help children develop healthy habits in ways that feel natural and fun.
The concept was born from a challenge familiar to virtually every parent.
“Like many parents, we were constantly reminding the kids to apply and reapply sunscreen,” they explain. “Especially during long summer days.”
The solution came in the form of Sunny Buddy, a UV-reactive temporary tattoo that changes color in the sun, serving as a visual reminder for children and caregivers alike to think about sun protection.
What began as a simple idea quickly revealed a much larger opportunity.
Once they shared the concept with other parents, it became clear they weren't alone. Families everywhere were looking for practical ways to encourage healthy habits without turning wellness into another daily battle.
The founders knew they had tapped into something meaningful.
For Sabrina, a Stroke Nurse Navigator at Greenwich Hospital, mother of two energetic boys, and current advanced practice nursing student at Yale University, prevention has always been central to her work. Throughout her healthcare career, she has witnessed firsthand how education and early intervention can dramatically influence long-term health outcomes.
Camila, originally from Ecuador, brings a complementary perspective through her background in business management and the beauty industry. Her passion for community-building, wellness, and accessible healthy living has shaped the company's approach to making prevention feel approachable rather than overwhelming.
While their professional backgrounds differ, their shared commitment to prevention and education created a natural foundation for partnership. Together, they bring a unique blend of clinical expertise, entrepreneurial vision, and real-world parenting experience to every product they develop.
“Prevention is often the most powerful form of healthcare,” says Sabrina.
That philosophy has become the foundation of Serein Wellness Co.'s mission.
Unlike many products in the wellness marketplace, Sunny Buddy isn't simply designed to solve a problem. It's designed to spark conversations.
The color-changing tattoos encourage children to actively participate in their own wellness while helping parents introduce important concepts like UV exposure, sunscreen use, and skin cancer prevention in a way that feels playful rather than intimidating.
“We wanted our products to feel educational rather than instructional,” they explain. “When children can see UV exposure and participate in protecting themselves, learning becomes much more engaging.”
That educational component has become one of the company's defining characteristics.
Every decision the founders make begins with a simple question: Would we use this with our own children?
As mothers balancing careers, advanced education, and family life, they understand the realities facing today's parents. Their goal isn't perfection. It's practicality.
They recognize that families are juggling packed schedules, competing priorities, and endless demands on their attention. That's why the most effective wellness tools are often the simplest ones.
For the founders, prevention isn't about creating fear or adding another responsibility to already busy parents. Instead, it's about helping families build awareness through small, manageable actions that become second nature over time.
They believe some of the most important health lessons begin long before a doctor's appointment is needed, often through everyday conversations that happen at home, on the sidelines of a soccer game, during camp, or at the beach.
“Parents are becoming much more proactive about prevention,” they explain. “They're looking for practical ways to support their family's health rather than waiting until problems arise.”
The response has been overwhelmingly positive.
Some of the most rewarding feedback comes from parents who report that their children now remind them to apply sunscreen. Others share stories of kids enthusiastically explaining to friends and family why their tattoo changed color and what it means.
Those moments represent exactly what Sabrina and Camila hoped to achieve.
Children aren't simply following instructions. They're actively participating in their own wellness journey.
Building the business hasn't been without challenges.
Launching a company while balancing motherhood, careers, graduate studies, and family responsibilities requires extraordinary commitment and flexibility. Yet both founders agree that watching their ideas evolve from conversations and sketches into products used by real families has made every challenge worthwhile.
The support they've received locally has been equally meaningful.
Greenwich's active, family-oriented culture has provided an ideal environment for growth. With children participating in sports, camps, beach days, and outdoor activities throughout the year, the community naturally values wellness, education, and prevention.
The encouragement they've received from local families, healthcare professionals, and fellow entrepreneurs has reinforced their belief that parents are eager for practical tools that make healthy habits easier to maintain.
That support continues to fuel the company's next chapter.
In addition to expanding the Sunny Buddy line, Serein Wellness Co. is exploring additional preventative wellness products, including migraine and neurological wellness offerings inspired by Sabrina's neuroscience background and the founders' shared passion for holistic health.
While the product line may continue to evolve, the mission remains remarkably consistent.
The founders hope families walk away with a simple realization: wellness doesn't have to be complicated.
Small habits practiced consistently can create lasting impact.
If a child learns about sun safety, remembers to apply sunscreen, or starts a conversation about skin cancer prevention because of Sunny Buddy, then Sabrina and Camila consider that a success.
As Serein Wellness Co. continues to grow, the founders remain focused on helping families see wellness not as an overwhelming destination, but as a collection of small, meaningful choices made every day. Whether through sun safety, neurological wellness, or future educational products, they hope to continue creating tools that empower parents and children to take an active role in their health—one simple habit at a time.
Because sometimes the most meaningful healthcare begins not in a doctor's office, but in everyday moments between parents and children.
And sometimes, those moments start with a color-changing tattoo.
