Ruby points

What are ruby points?

Ruby points, also called cherry angioma, are a cluster of tiny capillaries at the surface of the skin. They’re usually found on people aged 30 and older. The collection of small blood vessels inside a cherry angioma gives them a reddish appearance.

What are the causes for ruby points?

The exact cause of ruby points is unknown, but there may be a genetic factor that makes certain people more likely to get them. They’ve also been linked to pregnancy, exposure to chemicals, certain medical conditions, and climate. There also appears to be a link between cherry angiomas and age. They often begin to appear when individuals reach 30 years old and seem to increase in size and number with age. One study noted that over 75 percent of people over 75 years old have them.
