Please help, do I have folliculitis or keratosis pilaris? (photo)

I have been suffering constantly for 3yrs. I have not changed my diet or life style. I wax monthly and exfoliate daily. I have made numerous trips to the Drs and they only give me antibiotics which never work and salicylic acid which also does nothing. I've tried and tested all sorts of expensive creams and lotions online and nothing relieves it. I have fair skin but I tan very easily, my body hair is generally thick and dark, however waxing helps reduce the thickness usually.
