Although the skin is a dynamic organ capable of regenerating itself after injuries, some injuries cause the skin to heal with scarring. Scars can develop after inflammatory acne, infections, burns, inflammations, injections, surgeries, stretch marks, simple scratches, etc. Other times, they can form a raised scar or keloid as a result of too much scar tissue in the wound.
It is impossible to predict how well the skin will heal after any trauma, as genetics and concomitant health-related conditions play a significant role in regulating the healing process.
Scar treatment may encompass a variety of methods. Keloids and hypertrophic scars may be treated by a combination of injections, IPL, laser resurfacing treatment, and even Botox. There is not one specific treatment to treat all scars; instead, it is a step-wise approach.
