Rosacea is a disorder of both superficial and deep blood vessels. The small, thin walled superficial blood vessels exhibit physical damage and become hyper-responsive. The deeper blood vessels do not undergo physical damage, but are the main pathways through which large volumes of blood enter the superficial blood vessels of the face. These deeper blood vessels are hyper-responsive to neural and hormonal factors.
