  1. hello

    pimples mainly over the chest and upper back is usually due to seborrheic dermatitis.

    other cause can be acne vulgaris.

    to differentiate between the two I need to know if you also have dandruff and/or itching.
    also over the face whether the lesions are predominantly over forehead or cheeks.

    I suggest that we should arrive at a diagnosis first before starting any treatment. so please follow up with a photo and above answers.
