“…In vitro experiments proved that quercetin suppressed MMP-9 in two cell lines exposed to P . acnes [ 27 ]. Kaempferol exerts an inhibitory effect on ERK1/2 phosphorylation [ 41 ] and prostaglandin synthesis by suppressing COX-1 and COX-2 enzyme activity [ 28 ].…”

“…Compared with the other compounds, quercetin had the highest degree value in the network. is compound also exhibits an inhibitory effect on proinflammatory cytokines and chemokines such as IL1β, IL8, IL6, and TNF-α from P. acnes-stimulated human keratinocytes and monocytes [27]. Kaempferol has a moderate antibacterial activity and an inhibitory effect on P. acnes growth [28,29].…”

“…Studies have shown that quercetin has broad-spectrum antibacterial activity; the antibacterial activities destroy the bacteria's cell wall and change cell permeability, affecting protein synthesis and expression, reducing enzyme activities, and inhibiting nucleic acid synthesis [5]. Lim et al (2021) [6] studied that quercetin has antibacterial activity against Propionibacterium acnes-induced skin disorders by significantly trimming down the pro-inflammatory cytokine production in various P. acnes-stimulated cell lines by reducing the TLR-2 expression, matrix metalloproteinase-9 (MMP-9) mRNA levels, and phosphorylation of mitogen-activated protein kinase (MAPK). Other than that, Vipin et al (2019) [7] stated that quercetin completely inhibited virulence factors, including biofilm formation, and showed a significant protective effect on HEK 293T cells infected with P. aeruginosa strains.…”

“…[4][5][6][7][8][9] For example, quercetin, a polyphenolic flavonoid compound in numerous plants, induces antiinflammatory effects by attenuating toll-like receptor (TLR) 2 pathway signaling. [10][11][12] Several key results regarding the determinants of the severity of inflammatory acne have been obtained in recent years; (1) patients with more severe acne have lower C. acnes strain diversity than healthy individuals and (2) the relative abundance of C. acnes in metagenomic studies is similar in patients with acne and healthy individuals (though there are some reports of slightly higher levels in healthy individuals), indicating that C. acnes overgrowth is not associated with the severity of acne. [13][14][15] In other words, a loss of diversity in the skin surface microbiome and loss of balance between C. acnes phylotypes are thought to trigger acne.…”
