Acne scars are permanent textural changes and indentations that occur on the surface and underlying layers of the skin as a result of severe acne.
The scars are formed when damage occurs at the the deep layer of skin called the dermis. To repair the damage done, our skin begins to form new collagen fibres.
Unfortunately, the skin doesn’t look as smooth and flawless as before the injury. The replacement fibres have a different texture and quality compared to the tissue surrounding the area. This is what forms the scar.
