Glow started with a notebook full of recipes that Ji-Young Park's grandmother kept in a drawer next to her rice cooker. Fermented rice water, camellia oil pressed cold, green tea steamed over a clay bowl every morning at 5am.

Ji-Young grew up watching these rituals and wondering why no brand had ever taken them seriously — not as marketing copy, but as actual formulation starting points. So she partnered with a Seoul cosmetic chemist and spent two years translating each recipe into clinical actives without losing the soul of the original.

The result is a line that your grandmother would recognize and your dermatologist would approve.
