Telangiectasias are small blood vessels that you can see just below the surface of the skin. They may appear as a single vessel or a cluster of vessels. Telangiectasias can also appear in the mouth, eyes, and brain.
Small blood vessels become stuck in a wide open position. This makes them more visible. It is not always clear why this happens. Some may have related conditions, such as rosacea.
It is most common in women and people aged 40 years and older. There may also be an increased chance in those with a family history.
Symptoms are red lines under the skin that:
May appear in a lacy pattern
Can appear anywhere on the body, but are most common on the face, nose, and legs
Most often painless but some may have a burning sensation or bleeding
You will be asked about your symptoms and health past. A physical exam will be done. A diagnosis is often made during the exam.
Telangiectasias do not always need treatment. They rarely cause health concerns. However, some may not like how they look.
Make-up can be used to cover the red patches. The blood vessels can be destroyed with laser therapy or chemicals. These treatments are not appropriate for everyone.
