I am 1.5-2 months post Accutane and am developing small bumps or closed comedones on my forehead, what should I do? (Photo)

I was on isotretinoin for just over a year and had gone from cystic acne on my face and back to nothing. However post accutane, small closed comedones very deep within the skin which almost look rash like, have formed only on my forehead and I am very worried. Should I revisit my dermatologist and try accutane again or should I look into benzoyl peroxide creams or other topical creams? At the moment I am using a mild organic exfoliator, witch hazel and tea tree facial moisturiser.
