Hyper pigmented patches on face could be melasma or lichen planus pigmentosus
or pigmented variant of actinic LP. The diagnosis can only be confirmed by skin biopsy
. Clinically more or less they might appear to be same. As far as treatment is concerned it is basically the same for all to some extent as involves sun avoidance, use of sunscreens and pigmentation reducer creams. Actinic LP and LPP may require a course of oral steroids
or vitamin a
derivatives or hydroxychloroquine
Hope that helps. Take care
