Did you mean Atrophic Scars?

Glossary Atrophic Scars

sunken scars caused by tissue loss and collagen deficiency

Atrophic scars are a type of scar that appears sunken or depressed below the surface of the surrounding skin. They occur when the skin is unable to regenerate tissue, often due to conditions like acne, chickenpox, or trauma, leading to a loss of collagen and other structural components. These scars are characterized by their pitted appearance and can be challenging to treat, often requiring specialized dermatological procedures to improve their appearance.
