hi Welcome to Healthcare Magic Forum You seem to have developed sun burns due to excessive sun exposure... You need to apply a topical steroid containing mometasone cream over the affected area atleast twice a day over the affected area inorder to decrease the inflammation.. And take some oral antihistamines like levocetrizine once a day. You should use a sunscreen (spf 26) everytime before you go out in the sun in future,.. Regarding a sunscreen, it is important that you should apply adequate amount of sunscreen over all the exposed areas before going out in the sun,,It should atleast be applied 30 minutes before any kind of sun exposure and it should be reapplied every 3-4 hours in you stay out in the sun... Keep yourself hydrated by drinking lot of water If an case you develop any kind of pigmentation over face after the lesions heal,then you might have to apply a lightening agent like kojic acid over the affected area Hope it helps Dr Geetika Paul
