Answer

Rosacea involves associated damage to the endothelium and degeneration of the dermal matrix. However, it is not known whether the initial damage is in the dermal matrix and this leads to poor tissue support of cutaneous vessels, causing pooling of serum, inflammatory mediators, and metabolic waste, or whether the initial abnormality exists in the cutaneous vasculature and this leads to leaky vessels and delayed clearance of serum proteins, inflammatory mediators, and metabolic waste, thus resulting in matrix degeneration.
