Fig. 6. Biofilm biomass (OD590) of Cutibacterium acnes and Staphylococcus epidermidis grown as mono-cultures or co-cultures and treated with 2% salicylic acid (SA), cleanser (CL), serum (SR), crude four-herb extract (HE), or the individual herbal extracts including Houttuynia cordata (HC), Scutellaria baicalensis (SB), Chamaecyparis obtusa (CO), and Artemisia capillaris (AC). Biofilms were quantified by crystal violet staining and measured at OD590 after (A) C. acnes mono-culture for 48 h, (B) S. epidermidis mono-culture for 48 h, and co-culture at initial C. acnes:S. epidermidis inoculation ratios of 5:5 for (C) 24 h and (D) 48 h, 7:3 for (E) 24 h and (F) 48 h. Asterisks indicate statistical significance for the indicated comparisons: *p < 0.05, **p < 0.01, ***p < 0.001, and ****p < 0.0001; ns, not significant.
