Telangiectasias are common dilated blood vessels that can appear anywhere on the body, regardless of age or gender. The risk factors involved in their formation can vary depending on the location of the telangiectasias. The main factors that increase the risk of telangiectasia include:
* Prolonged sun damage in sun-exposed areas like the face
* Skin thinning due to aging
* Long-term corticosteroid use
* Various skin conditions such as rosacea
* Rheumatic diseases like lupus
* Prolonged standing, especially for telangiectasias in the legs
* Pregnancy and oral contraceptive use (in situations where estrogen levels are elevated)
If telangiectasias are widespread throughout the body, it is important to investigate underlying liver diseases, rheumatic conditions, or certain infections.
