Fig. 3. The gene expression of inflammatory biomarkers in cultured sebocytes treated with light at a wavelength of 650 nm did not show a significant change compared to that in the control. The expression level of each gene was normalized to that of β-actin and presented as a relative ratio. Error bars represent standard errors calculated based on three independent experiments. IL: interleukin, TNF-α: tumor necrosis factor-α, MMP: matrix metalloproteinase, hBD: human β-defensin.
