Hello,
It looks like lichen planus pigmentosus but still need to good clinical photographs as these pictures are over exposed and even details regarding onset of lesion is required
Next Steps
You can take anti- allergic medication like tablet Levo cetrizine 5 mg at night for symptomatic relief as only moisturizer doesn't work in such conditions and proper treatment is to be planned
