Jae Won Jeong

Consumer-goods operator who entered K-beauty through a process — fermentation — rather than an ingredient, and patented a black-rice extraction method to anchor a fragrance-free, vegan, daily-ritual brand named for the Korean word for 'everyday'.

"Building a business takes more than a great idea; it takes the tenacity to navigate every moving part with empathy at the centre."

— Jae Won Jeong
Background

Jae Won Jeong came to Haruharu Wonder from product development and consumer goods rather than pharmaceutical chemistry. Her intellectual entry point into skincare wasn't a single active but a process: fermentation — the ancient Korean food preservation technique she recognised as the most underutilised scientific resource in formulation.

She obtained a patent for the brand's proprietary fermented black rice extraction process, which she describes as producing antioxidant potency 30 times greater than unfermented black rice. Her consumer-side argument is that women who use beauty products daily generate product insight that no laboratory protocol can replicate.

BeautyMatter named Haruharu Wonder in its Future 50 for 2026 — the only Korean clean brand in that cohort — and Target US added the brand to its 2025 K-beauty expansion alongside Beauty of Joseon and Biodance.

Philosophy

Empathy before science. Lived experience generates the brief; fermentation technology executes it.

Gentle innovation is not gentle ambition. Plant-powered, fragrance-free, certified-vegan formulations can still deliver measurable barrier outcomes.

The name and the architecture are inseparable: 'everyday' has to mean a ritual that doesn't exhaust the skin or the consumer.
