If you've scrolled TikTok lately, perhaps you've come across a sunscreen from K-beauty brand Beauty of Joseon. On the app, it's somewhat ubiquitous. Sumin Lee is part of a team that acquired the brand and totally reinvented it, introducing the version today's U.S. consumers know in 2019. In the five years since, it's become a hit, particularly for its sunscreens, including the Relief Sun Aqua-Fresh: Rice + B5 (SPF50+ PA++++). It not only uses advanced SPF filters that were previously unavailable in the U.S., but it's also relatively affordable, at $18.

The brand has taken off not only on TikTok Shop but also on Amazon. Lee credits the sunscreen's success to both its super-lightweight texture and TikTok itself. The brand is formulated around "hanbang" ingredients, meaning the formulas feature traditional Korean herbs as key ingredients.

On this week’s episode of the Glossy Beauty Podcast, founder Sumin Lee discusses the brand's exceptional popularity in the states, especially compared to Korea, its upcoming retail expansion in the U.S. and its strategy for combatting counterfeiters.
