What are dilated capillaries beneath the surface of the skin called?

Dilated capillaries beneath the surface of the skin are known as telangiectasia. These are small, visible blood vessels that often appear as red or blue lines, particularly on areas such as the face and legs. They result from various factors, including genetics, sun exposure, and skin conditions. Understanding telangiectasia is important for estheticians, as they may encounter clients with this condition and need to tailor treatments accordingly.

Other terms, while related to skin conditions, denote different issues. For instance, rosacea is a chronic skin disorder characterized by redness and visible blood vessels, but it encompasses more than just telangiectasia and includes symptoms like flushing and inflammation. Hyperpigmentation refers to darkened areas of the skin due to excess melanin production, typically as a result of sun exposure or hormonal changes. Vasodilation is the process by which blood vessels widen, usually in response to heat or other stimuli, but it does not specifically refer to the condition of dilated capillaries. Understanding these distinctions helps in identifying and addressing various skin concerns in a professional setting.
