Su:m37 is one of Korea’s most prestigious skincare houses, celebrated for its dedication to natural fermentation science. Every formula is crafted using over 80 carefully selected botanicals, fermented at a constant temperature of 37ºC for up to a year, unlocking the skin-restoring power of nature at its peak.

At the heart of the brand lies the Secret Essence, a global icon often called the “miracle of fermentation.” Lightweight yet powerful, it deeply hydrates, refines texture, and restores balance to dull, tired skin. Other standouts include the Bright Award Bubble De Mask Black, which oxygenates and purifies, and the luxurious Losec Summa Elixir line, designed to target visible signs of ageing.

Beloved by those who seek rare, artisanal Korean formulations, Su:m37 blends traditional fermentation with modern dermatological innovation. Each product is free from artificial fragrances, colours, and synthetic preservatives, staying true to the brand’s philosophy of “breathing skin.”
