Acne happens when dead skin cells, bacteria, and/or oil builds up and clogs our hair follicles, forming whiteheads and blackheads. When inflammation happens, pimples or even cysts will form. Usually occurring on the face, chest and back, it is a skin condition that leaves people exasperated as it can affect their confidence and self-esteem. Not only that, acne can be painful, itchy, and some might take a long time to heal.
