Post-acne scars

Post-acne scars are the marks or indentations left on the skin after an acne breakout has healed. These scars can vary in appearance, ranging from pigmented spots to more pronounced depressions or raised areas on the skin. There are several types of post-acne scars:

1. Hyperpigmentation: This is the most common type of post-acne mark. It appears as darkened spots or patches on the skin where the acne lesions once were. Hyperpigmentation occurs due to an overproduction of melanin in response to inflammation.
2. Atrophic Scars:Atrophic scars are depressions or indentations in the skin that result from the loss of tissue during the healing process. There are three main types of atrophic scars:
   • Icepick Scars:These are deep, narrow scars that extend into the skin in a V-shape.
   • Boxcar Scars:These scars are broader and have well-defined edges. They often appear as round or oval depressions in the skin and can vary in depth.
   • Rolling Scars:Rolling scars have a wavy appearance due to the underlying fibrous bands that pull the skin downwards, creating an uneven texture.
