Work out what caused a scar and how the skin responded to it. Do that, and you are halfway to choosing the treatment that will improve it. A handful of causes account for most of the scars we see at MediZen.
Acne is the most common by far. When a breakout pushes deep into the skin it damages the tissue underneath. The repair that follows often heals as a pitted or discoloured mark. Injury and surgery make up the next largest group, from kitchen burns and sports grazes to caesarean and operation lines. Chickenpox and other infections leave their own small, round depressions, often on the face. Stretch marks form when skin is pulled faster than it can adjust. This happens through growth spurts, pregnancy or quick changes in weight. Beneath a surface that stays intact, the dermis tears.
Two things then decide how visible the result becomes. The first is genetics, which set how readily you scar and whether you carry a tendency to keloids. The second is what happens while the wound heals. Several things can deepen the final mark. Picking at a spot and tension across the skin both play a part. So does a slow-healing or infected wound, or sun exposure on fresh scar tissue. The NHS guidance on scars is a clear, plain-English summary of how they form and settle over time.
