What is telangiectasia?

Telangiectasia refers specifically to the condition characterized by distended capillaries and small blood vessels that become visible on the surface of the skin. This condition often appears as fine, red or purple lines and can be associated with various factors, including genetic predisposition, sun exposure, or certain medical conditions. It is commonly seen in conditions like rosacea or as a result of certain dermatological treatments. Understanding this condition is essential for identifying vascular concerns on the skin and differentiating it from other skin issues such as thickened skin, localized swelling, or fungal infections, which have distinct characteristics and underlying causes.
