Possibly she is taking minocycline, minocycline induced pigmentation.

I don’t think this is minocycline-induced pigmentation since it is negative for Prussian blue, but I agree this is postinflammatory pigmentation due to photosensitizing agent.

There is a report about a type IV minocycline induced pigmentation that was confined to acne scars and was negative for iron stain but positive with calcium stain. Could it be this case.
