Best Su:m37° Products for Combination Skin
3 Su:m37° picks that actually work on combination skin — ranked by editor rating, not by what the brand pushes hardest. Updated 2026.
Su:m37° bet its entire identity on one idea: ferment everything, for exactly 365 days, and don't add synthetic preservatives. The Secret Essence is what happens when that philosophy actually works — a naturally-fermented essence with legitimate cult status. Not cheap, not preachy, and the formulas have held up for 15+ years.

8.8/10 · essenceSecret Essence
LG's answer to SK-II Pitera — a naturally fermented essence that takes 50+ days in controlled fermentation tanks. The glow is real, the texture is water-thin, and the ferment is genuinely different from galactomyces. If SK-II is the J-beauty first treatment essence, Su:m37° is the K-beauty equivalent.

8.5/10 · moisturizerWater-full Timeless Water Gel Cream
Su:m37°'s answer to the gel-cream category — a fermented-ingredient-led water gel that gives the brand's signature bounce-back skin feel without the heaviness of the LosecSumma flagship. The Water-full line uses a different fermentation complex than the Secret Essence (more bamboo + watercress, less mountain flower) and lands at a lighter, more daily-use texture. Recommended for K-beauty fans who want LG luxury formulation without the $200+ commitment of the brand's hero products. Particularly nice in summer or for combination skin.

8.3/10 · cleanserSkin Saver Essential Pure Cleansing Stick
Sum:37°'s most-imitated K-beauty product and the SKU that made cleansing sticks a category. Solid stick format that emulsifies into oil on skin contact, then foam with water — the convenience of an oil cleanser without the bottle. Camellia sinensis (green tea) leaf extract + tocopherol + bisabolol for the soothing-antioxidant base. Korean travel beauty staple.
