Scarring is the natural healing response of the skin after an injury, wound, or surgery. While scars are a normal part of tissue repair, they can vary in size, texture, and visibility, sometimes leading to raised, discolored, or indented marks on the skin. The appearance of scars depends on the depth of the injury, skin type, and how the wound heals. While some scars fade over time, others may become more prominent and require targeted treatments to improve skin texture and tone.
