Science
Mechanism of Action
This ingredient operates as a biosurfactant known as a sophorolipid. It functions via a targeted enzymatic pathway, inhibiting 5α-reductase to decrease excess sebum production while deploying selective antimicrobial activity against C. acnes and Malassezia, effectively neutralizing pathogens without disturbing the beneficial skin microbiome.

Clinical Evidence
High confidence2%
Key findings
- 01 A 2.0% concentration demonstrated a 11.4% reduction in forehead sebum secretion within just 7 days.
- 02 In vitro testing at a minimal 0.05% concentration showed successful inhibition of Cutibacterium acnes growth.
- 03 A 28-day clinical trial using 1.0-2.0% concentrations resulted in a significant reduction of inflammatory lesions, including papules and pustules.
Transparency
Dusting Analysis
While antimicrobial benefits appear at very low levels (0.05%), the visible sebum-regulating and anti-acne results documented in clinical trials require a minimum of 1.0% to 2.0%. Formulas listing this ingredient near the very end of the INCI list likely fail to provide its full functional benefits.

Safety
Safety Profile
While a 2024 CIR report noted insufficient data for the hydrolyzed version, this non-hydrolyzed ferment is widely used in Europe and recognized in the CosIng database with a favorable safety profile.
