Previous studies showed that VEGF expression, angiogenesis and lymphangiogenesis increased in rosacea skin lesions (Gomaa et al., 2007; Smith et al., 2007), while another study indicated that dilated vessels were evident, with no or slight upregulation of key angiogenic genes and limited angiogenesis in papulopustular rosacea (Schwab et al., 2011). Here, VEGFA is linked to rosacea.
