RETTRE Yeonmujang-Gil

RETTRE Yeonmujang-gil is a boutique fragrance workshop in Seongsu that offers a unique perfume-making experience powered by brain spectroscopy. Visitors formulate bespoke scents based on brainwave responses to personal photos and memories. The experience includes completing a sensory survey, testing fragrances, and decorating a custom keepsake canister.

Commenters are deeply intrigued and touched by the concept of translating meaningful personal memories and photos into custom scents. Many view it as a prime destination for romantic dates or wedding keepsakes, though several ask about workshop pricing and the longevity of the final scent quality.
