What Could Trigger Skin Tags? 15 Possible Causes

Skin tags are small, harmless growths that develop from the skin’s tissue. They typically appear as small and fleshy protrusions on the skin, with a size similar to a grain of rice. While they’re most common on the neck, armpits, eyelids, and groin area, they can appear anywhere on the body.

The scientific community has not yet determined the exact causes of skin tags. It is known that they are related to the excess growth of the cells that line the body’s outer layer. However, it is unclear why these cells grow in excess or whether this process is benign or a sign of a condition that may become more serious.

It is believed that some people develop skin tags due to heredity, while others may develop them due to injury to an area of the body. In addition, some people develop skin tags due to friction from clothing, jewelry, and other objects. Anyone can remove skin tags for cosmetic or even medical reasons if irritated or infected.

In this article, we will cover various causes of skin tags, including the most common causes. We will also discuss how to prevent skin tags from forming and how to treat them if they do develop.


Heredity is a cause of skin tags. Heredity can be determined by the genes you inherit and pass down to your offspring. Skin tags are caused by genetics and environment, but heredity plays a part in their development. The inherited genes are linked to the immune system, which is why skin tags tend to affect family members.

Hereditary factors are an important cause of skin tags. In rare instances, a child may inherit one or more of the genes that cause skin tags from a parent, grandparent, or close relative. Such children may develop skin tags at an early age. Sometimes, multiple family members have the same type of skin tag.

Hereditary skin tags also tend to run in families among identical twins. This is thought to be caused by a genetic mutation in the DNA that codes for keratin production, a protein essential for healthy skin tissue growth.
