Hi, you are having post inflammatory
hypermelanosis following
lichen planus. The
melanin pigments are in dermis, that is why they are not cleared with local
steroid or depigmentary agents. They will remove the color from surrounding skin , but affected skin will remain same. So, you avoid to apply any cream on it. The color may reduce by it self. Important thing is inactivity of lichen planus. So, be happy with it... Ok
