Sum37

Sum37°, also presented as sum37° and 숨37°, is a South Korean skincare brand operated by LG Household & Health Care Co., Ltd. Its official store identifies LG Household & Health Care as the company responsible for the storefront and describes the brand through the theme “Breathe with Nature.” The brand frames skincare as a way to help skin feel comfortable and emphasizes carefully selected plant ingredients, time, and fermentation as central parts of its identity. Fermentation is both a product-development theme and a prominent part of Sum37°’s brand story. The brand describes its Tru-Active™ complex as the result of fermenting 55 plants for ten years, and presents Biopeptide 190™ as a proprietary ingredient developed through research into microorganisms and sensitive skin. These are claims and descriptions made in the brand’s own materials. The brand also says that its fermentation approach is intended to deliver plant-derived ingredients and care for skin that has become sensitive. The official Korean-language shop lists skincare products including Secret Essence Advanced Treatment, Water-full Rebalancing Emulsion, Micro-Active Repair Serum, and Micro-Active Tone-Up Sun. Its assortment and brand narrative position it in skincare, with particular emphasis on essence, moisturization, serum, and sun-care products. The official site also communicates formulation and packaging principles: it says that some products exclude specified ingredients, some formulas meet an ISO 16128 natural-origin index threshold, all products have undergone skin irritation testing, and FSC-certified packaging is used. The site qualifies several of these statements as applying only to some products and clarifies that its natural-origin index does not mean the products meet the Korean regulatory definition of natural cosmetics. Sum37° is presented as a brand within LG Household & Health Care rather than as an independent company. The supplied official-store material confirms the corporate operator but does not establish the brand’s founding year, founder, headquarters, or specific overseas operating markets. The current store is in Korean and offers product sales, membership, customer service, and brand information. Its public positioning combines a nature-centered identity with fermentation-focused skincare and sustainability messaging.

Sum37° is a skincare brand operated by LG Household & Health Care Co., Ltd. The supplied official materials do not state when the brand was founded, identify a founder, or provide a dated account of its launch. The brand’s documented history in these materials is therefore best described through the identity and product approach it currently presents, rather than through unsupported dates or corporate milestones. The official brand story centers on the relationship between nature, time, fermentation, and skin. Sum37° says it selects plants and allows them to undergo a long process before incorporating their vitality into skincare. Its name is explained on the official homepage as referring to 37 degrees, described as an optimal temperature for fermentation and maturation. The brand’s story page expands on this theme with sections on fermentation, ingredients, and skin comfort. The brand identifies Tru-Active™ as a key ingredient concept. Its official page describes a ten-year fermentation process involving 55 plants and says that this process yields 40 nutrients. It also reports increases in certain active components compared with a one-year fermented ingredient. These are brand-published descriptions, not independently verified findings in the supplied evidence. Another named ingredient, Biopeptide 190™, is described by the brand as a proprietary patented ingredient developed through research involving more than 190 microorganisms and intended to help care for sensitive skin. The official page cites Korean patent number 10-2532713. The official Korean-language shop shows a product range spanning essence, emulsion, serum, and sun care. It lists Secret Essence Advanced Treatment, Water-full Rebalancing Emulsion, Micro-Active Repair Serum, and Micro-Active Tone-Up Sun among its best products. The assortment and accompanying brand story show how Sum37° translates its fermentation identity into consumer skincare offerings. The brand’s official materials also describe formulation and environmental commitments. They state that certain ingredients are excluded from some products, that some formulas have an ISO 16128 natural-origin index of at least 90%, and that all products have completed skin irritation testing. The page explicitly limits some claims to certain products and notes that the ISO index does not mean the products qualify as natural cosmetics under Korean regulatory standards. It also describes the use of FSC-certified packaging and other packaging materials framed as more sustainable. The official store attributes its operation to LG Household & Health Care Co., Ltd. and provides Korean customer-service information. The supplied evidence does not establish a brand founder, founding year, headquarters, or particular international markets. Accordingly, Sum37° can be documented here as an active LG Household & Health Care skincare brand whose public identity is defined by nature-oriented storytelling, fermentation, and a Korean online product assortment.
