The good news about scar treatment is that they can always be improved. Pigmented scars can be lightened, red and purple scars can be corrected, depressed scars can be raised, raised scars can be flattened and scar texture can improve. The reality is, it often takes multiple types of treatment to address each aspect of the scar, and even with great improvements, scars will never fully be gone.
Lasers can help change the pigment, red or purple color and texture of the scar. Fillers and mechanical subcision can be used to raise depressed scars. Various injectable treatments can flatten scars. The right combination of those treatments will depend on your individual needs, goals and anatomy. It takes an expert in scar revision to help choose and present your options, and you need someone who has all of those mentioned treatment modalities available.
