You can see a dermatologist to treat your dermal pigmentation, as it is treated differently than epidermal pigmentation. Is it the post-inflammatory hyperpigmentation, melasma, or another kind? Using a lightening creme that targets and inhibits the tyrosinase enzyme (responsible for the color) may help.
"Pulsed CO2 laser followed by Q-switched alexandrite laser in the treatment of dermal melasma that showed promising results (3). Nevus of Ota has effectively been treated with the selective photothermolysis with the Q-switched ruby laser as well. On the other hand, multiple therapies are available in the management of epidermal hyperpigmentation."
