About Us

Powerful with lush, native-grown botanicals, backed by leading science, and committed to creating a more balanced world—from soil to skin, and back again.

Our plant-powered formulas are designed to deliver the highest level efficacy for deep skin nourishment. Every product we make is a meticulous blend of potent, plant-derived actives proven to be highly effective, safe and stable.

The science is clear—not all ingredients work alike. The key to true efficacy is bioactivity, which is the percentage of nutrients in a particular substance that are actually available and active for your body to use.

We only source indigenous botanicals with high bioactivity, a natural benefit of plants being grown healthfully in their native, bio-diverse environments. It’s more laborious, requires considerable care and is, for us, non-negotiable.

Safe, stable, balanced

It’s our priority to engineer balanced formulas that are safe and stable. Our specialized extraction method requires zero solvents or harsh chemicals—just time and diligence—which enables us to extract pure constituents, optimized for your skin’s absorption. When developing our blends with natural active botanicals, we take great care to combine the powerful actives with safe, gentle synthetics to help stabilize and optimize efficacy across every single formula.

We put ourselves under the microscope

Integrity and purity are what we obsess about. And the only way to ensure quality with any ingredient is to go deep—molecular-level deep. We use state-of-the-art composition testing methods to analyze every material that we consider for a Circumference formulation. Only the highest bioactive extracts with the purest molecular signatures make it through.

This is how we translate (our) scientific insights into high-efficacy formulas.

More On Sustainability

Meet the Founder

You could say that Jina’s passion for skincare is in her blood. Growing up in a Korean household, healthy skin was a discipline passed down from her mother and aunts who considered taking care of your skin equally as important as taking care of your health. Self care had been tradition as well as routine for Jina from an early age.

Jina originally pursued a career in medicine studying physiology and chemistry at the University of Washington. But ultimately her desire for creative fulfillment inspired a career change which brought her to work with a number of creative agencies throughout her early career. It was her work in helping to launch a sustainable fashion line that opened Jina’s eyes to the possibilities and importance of positive, transparent manufacturing practices, which inspired her to think of what other industries could benefit from these positive practices. Harkening back to her love of skincare and self care, Jina naturally turned her attention toward an industry she felt was lacking in eco-conscious sensibilities—beauty. And Circumference was born.

Jina was inspired to bridge her passion in beauty with a desire to build a beauty brand that uses innovative sustainable solutions to create highly effective formulas. Sourcing beneficial ingredients that can be sustainably harvested, contributing to the communities where they come from, and proving how doing both can produce beautifully luxurious beauty products is one of Jina’s proudest successes in creating Circumference. It’s all about bringing the interconnected factors that impact our environment, society, and the economy into balance.
