👉 Allen's pimples, also known as perifollicular acne, are a specific type of acne characterized by small, red, inflamed pimples that appear around the base of hair follicles, typically in the T-zone (forehead, nose, and chin). These pimples result from the blockage of hair follicles by a mixture of sebum (oil), dead skin cells, and bacteria, leading to inflammation. Unlike larger comedones or papules, Allen's pimples are often smaller and more numerous, and they may be accompanied by white or yellowheads. This condition is commonly associated with hormonal changes, particularly in adolescents and young adults, but it can also occur in adults due to various factors like stress, diet, and hormonal imbalances. Treatment usually involves topical or oral medications to reduce inflammation and prevent future breakouts.
