The full picture
JISUN Firming Complex is Sulwhasoo's proprietary blend of five Korean herbs developed over more than 50 years of formulation research. The exact botanicals are part of the brand's IP, but Sulwhasoo positions the complex as supporting both moisture barrier strength and visible firmness. Korean Herb Extract on an INCI list typically refers to this same complex or a closely related botanical group. The Essential Firming Cream EX pairs it with adenosine (a Korean-regulator-recognized anti-wrinkle active) and squalane for comfort.
Evidence
Sulwhasoo reports a 4-week consumer study showing measurable elasticity and firmness improvement. Brand-direct data; the specific botanicals in the blend are not fully published.
