What is crease on forearm?

A crease on the forearm, also known as the supratrochlear crease, is a natural indentation or fold on the skin of the arm. It typically runs horizontally across the forearm just below the elbow joint. This crease is formed by the skin folding over the underlying muscles and tendons of the forearm.

In some cases, a prominent crease on the forearm may indicate higher levels of body fat or an unhealthy diet. However, in most cases, it is simply a natural part of the anatomy and does not require any treatment.

It is worth noting that some medical conditions, such as lymphedema or certain genetic disorders, may cause unusual or excessive creasing of the skin on the forearm. If you are concerned about any unusual physical symptoms or changes in your body, it is always best to consult with a healthcare professional.
