About the Brand
SU:M37 is a luxury Korean skincare brand owned by LG Household & Health Care, launched in 2007 with a philosophy centered on the power of natural fermentation. The brand name combines 'su:m,' the Korean word for breath, and '37,' representing the optimal temperature for fermentation, which is also the temperature of the human body. Its signature technology is Cytosis, a proprietary complex derived from the fermentation of over 80 different seasonal botanical ingredients over 365 days to maximize potency and skin absorption. The brand is best known for its iconic Secret Essence, a cult-favorite product designed to improve skin tone, texture, and elasticity. Positioned in the premium luxury market, SU:M37 emphasizes clean, non-synthetic formulations that are free from artificial fragrances, colors, and preservatives. The brand operates its own dedicated fermentation research institute to ensure the quality and efficacy of its naturally derived actives. It offers a wide range of collections, including the hydrating Water-full line, the brightening White Award series, and the anti-aging LosecSumma range. SU:M37 has gained significant international recognition for its innovative approach to fermented skincare, appealing to consumers seeking effective, gentle, and scientifically backed beauty solutions.
