What is telangiectasia?
Telangiectasia refers to small, visible blood vessels near the skin’s surface, often caused by inflammation, sun damage, or underlying vascular conditions.
They are sometimes seen on the scalp and can signal areas of previous trauma or sensitivity, especially after laser or topical treatments.
Red light therapy is generally well-tolerated, but care should be taken around telangiectasia-prone areas, especially in individuals with rosacea or vascular fragility.
