Post-injury hyperpigmentation can be treated by laser therapy, oral medication and topical medication.
1. Laser treatment: This kind of method refers to the action of laser energy on the dermis layer of the skin to break up the pigmentation, and with the metabolism, the pigment will be discharged out of the body, so as to achieve the effect of eliminating hyperpigmentation.
2. Oral medication: Vitamin C, tranexamic acid and other medications have the effect of lightening hyperpigmentation and reducing the formation of pigmentation, which can prevent further pigmentation.
3. Topical medication: Hyperpigmentation after injury can also be treated by local use of some spot-reducing medications, such as hydroquinone cream, tretinoin, and so on.
If the above situation occurs, it is recommended to go to the regular hospital for treatment. The medicines need to be applied under the doctor’s advice.
