What is a telangiectasia?

A telangiectasia is defined as small, dilated blood vessels that are often visible on the surface of the skin. These blood vessels can appear as thin red or purple lines and are commonly associated with conditions that cause vascular changes, such as rosacea or sun damage. They are not raised bumps or thickened areas of skin, which distinguishes them from other skin lesions. The presence of telangiectasia can indicate various underlying health issues or skin conditions and is often a focus in dermatological assessments. Understanding this term is crucial for accurate diagnosis and treatment in the field of cosmetology and skincare.
