Ordinary scars have shapes and sizes corresponding to the location of the wound. They do not protrude or indent more than the skin's surface and generally have colors relatively similar to the surrounding skin.
Raised scars or hypertrophic scars elevate from the skin due to an excess production of collagen fibers during the wound healing process. These scars extend beyond the original wound boundaries, invading adjacent skin areas. Raised scars are typically not physically discomforting, except for cosmetic concerns. However, some types may cause itching, mild pain, or a tight sensation.
Depressed scars form due to the deterioration of collagen fibers and subcutaneous fat. Depressed scars account for the majority, ranging from 80% to 90%, of all scar treatments.
Scars typically develop after skin injuries, such as:
However, raised scars are specifically formed due to the following factors:
Various methods can be employed to treat scars, each with varying degrees of success. Scar treatment on the skin surface aims to address cosmetic concerns.
– CO2 Laser Therapy: Ideal for newly formed scars, but less effective for older scars with increased fibrosis.
– Scar Revision Surgery: Considered for hypertrophic scars affecting function, at least one year post-injury and in a stable phase.
– Fractional CO2 Laser: Uses CO2 laser beams to create micro-injuries, stimulating deep skin regeneration and collagen production. This method is suitable for scars of moderate to deep severity, including both raised and depressed scars.
– Microneedling: External impact on the skin using many small, sterilized needles rolled in various directions. This creates small injuries on the skin, promoting collagen production and maintaining skin elasticity.
