Pigmented scars, i.e. scars with hyperpigmentation, are mostly caused by skin inflammation or trauma, and can be restored through medication, injections and fillers, lasers and other treatments. 1. Drugs: Generally, after the skin heals from inflammation and trauma, the local fibrous connective tissue proliferates or atrophies locally, causing scars with hyperpigmentation. Early on, medication can be used, such as silicone gel, etc., which can promote the softening and thinning of scars; secondly, local injection of glucocorticoid drugs such as Triamcinolone acetonide, etc., which can promote the softening of scars, can also be prescribed by the doctor. 2. Injectable filler: When the scars appear obvious depression, can be in the doctor’s operation, the depression for injection filling treatment, filler materials generally have hyaluronic acid, collagen, etc., of which collagen can have a certain whitening effect. 3. Laser: Scars with hyperpigmentation can usually be treated with laser under the operation of a doctor, in which the carbon dioxide laser can make use of the photothermal effect, not only smoothing out the effect of scars, but also lightening the effect of hyperpigmentation. If you have scars with hyperpigmentation, it is recommended that you go to the hospital in time for reasonable treatment under the guidance of a doctor.
