A pimple is a small, raised bump on the skin that occurs when hair follicles become clogged with oil, dead skin cells, and bacteria. This condition is commonly associated with acne, which can affect people of all ages, but is most prevalent during puberty due to hormonal changes. Pimples can appear on various parts of the body, including the face, back, and shoulders. Pimples can vary in size and severity, ranging from small whiteheads to larger, inflamed cysts. They may be red and tender, indicating inflammation, or they can be filled with pus. Proper skin care and hygiene can help prevent pimples, while treatments like topical creams and oral medications are available for those with more severe cases.
