What are telangiectasias?

Telangiectasias are characterized as dilated capillaries, which are small blood vessels in the skin that have expanded and become visible. These dilated vessels often appear as red or purple lines or patterns on the surface of the skin and can be a result of various factors, including sun exposure, hormonal changes, or certain medical conditions. Understanding telangiectasias is important in dermatology, as they can indicate underlying vascular or skin issues and may require treatment for cosmetic reasons or to address any potential health concerns. The recognition of these vascular changes helps in diagnosing conditions related to skin health, making the understanding of telangiectasias essential for anyone studying skin science.
