An atrophic scar looks sunken and has a pitted appearance. These scars happen because underlying structures supporting the skin, such as fat or muscle, are lost. This type of scarring is often seen in acne, chickenpox, other diseases (especially Staphylococcus infection), surgery, certain insect and spider bites, or accidents. Atrophic scars can also be common in genetic connective tissue disorders, such as Ehlers-Danlos syndrome.

Atrophic scars are sunken, pitted marks caused by the loss of underlying support like fat or muscle. Common after acne, infections, or injury, they reflect deeper skin damage and structural loss.
