Acne, as we all know, is caused by oil, germs, dead skin cells, and dirt being clogged in the pores. When this happens, a pimple or blemish can appear anywhere on your body, although it's most common on the face, shoulders, back, neck, chest, and upper arms. You may have acne if this problem affects your skin on a regular basis. Acne is the most prevalent skin problem, and it may be excruciatingly unpleasant, especially when severe. It can also induce mental anguish.
