Acne scars develop as a result of the skin’s healing process after severe acne lesions. When the skin undergoes inflammation and tissue damage, the body attempts to repair itself, leading to the formation of scars. Severe forms of acne, including nodules and cysts, are more likely to cause scarring. These lesions penetrate deeper into the skin, affecting the surrounding tissue and collagen. Scar tissue is characterized by a different composition of collagen fibers compared to normal skin tissue. It often lacks the regular pattern and elasticity of healthy skin, resulting in a distinct texture and appearance.
