    Glossary Acne Scars

    result of inflamed acne lesions damaging skin tissue

    Acne scars, also known as post-acne scars, are the result of inflammation within the dermal layer of skin brought on by acne. When the acne pore swells, it causes a breakdown in the wall of the pore, leading to the formation of scars. These scars can manifest as depressions (atrophic scars) or raised areas (hypertrophic scars) on the skin, and they often require specialized treatments such as laser therapy, chemical peels, or microneedling to improve their appearance.
