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."

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.
