Ixora parviflora Protects against UVB-Induced Photoaging by Inhibiting the Expression of MMPs, MAP Kinases, and COX-2 and by Promoting Type I Procollagen Synthesis

Figure 6

Effect of Ixora parviflora extract on the UV-induced MMP-1 (a), MMP-3 (b), MMP-9 (c), and TIMP-1 (d) expression in human fibroblasts. (𝑛=4; significant difference versus control (non-UV-exposed): ^∗∗∗𝑃<0.001. Significant inhibition versus UV-exposed group: ^#𝑃<0.05; ^###𝑃<0.001. EGCG: (−)-epigallocatechin gallate.).
