Founder
Perilla Guard began as a skincare innovation project exploring the natural UV-protective potential of Perilla seed extract. My work focuses on developing eco-safe, plant-based sunscreen formulations that protect human skin while preserving marine ecosystems.
What began as an experiment in the lab has grown into a full research project combining science, sustainability, and community collaboration.
In addition to creating a reef-safe, skin-friendly sunscreen, Perilla Guard increases income opportunities and introduces new applications for Perilla cultivation in Thailand’s northern hill regions, ultimately empowering farmers while advancing sustainable skincare innovation.
Pammy's Story
Ever since I was young, the sea has felt like home. I spent my childhood swimming, kayaking, and exploring the water. I have always been happiest when surrounded by the ocean’s calm and color. As a child, I couldn't use regular sunscreen because I was allergic to chemical formulas. My skin would react, and I would end up choosing between enjoying the sea and protecting myself from the sun.
That challenge became the seed of something bigger — a curiosity to find a better, more natural way to stay safe under the sun. As I grew older and started diving, I began to see how conventional sunscreens also harm the very ecosystems I loved: coral reefs and marine life.
Those experiences inspired me to create Perilla Guard, a project that combines science and sustainability to develop coral-safe, skin-friendly sunscreen made from Perilla seed extract. It’s my way of giving back to the ocean that has always given me peace, joy, and purpose.
