How to Determine if a Face Blemish Is a Wart or Pimple
Facial blemishes are highly noticeable because of their location. Pimples are common facial blemishes. Facial warts are less common, as are bug bites, scratches and sores from other causes. You must know the blemish type to treat it properly. Pimples and warts both have distinguishing characteristics that let you tell them apart if you study them closely.
Pimples come from acne, a common skin disorder among teens and some adults. Some are simply swellings caused by blocked pores, while others get pus inside or turn into hard bumps. Warts are abnormal skin growths caused by a virus. Pimples most commonly appear on the face, although acne can affect your chest, shoulders, back and other areas. Warts are more likely to grow on your fingers, hands and feet, although two types tend to grow on your face, according to KidsHealth.org. You can tell these two skin problems apart mainly by their appearance.
Facial warts primarily come in two types. Flat warts are tiny and smooth, usually growing no larger than a pinhead and appearing in clusters, while filliform warts are larger and shaped like a thin finger, according to the American Academy of Dermatology. Filliform warts are the same color as your skin and generally appear by your eyes, nose or mouth, while flat warts vary in color. They may be pink, yellow or light brown and appear anywhere on your face, as well as on your hands, arms and knees. You can also get a common wart on your face, which is a rough bump that may be dotted with small black specks. Warts can spread, since they are viral, and washing helps prevent them.
Pimples have several lesion types, like blackheads, whiteheads, pustules, papules, nodules and cysts. Some pimples are barely noticeable, while others are large, inflamed and likely to cause a scar. Acne varies in appearance from small pink or red bumps with a black, white, or yellow top, depending on whether the follicle is partially or completely blocked and whether it is inflamed, according to the National Institute of Arthritis and Musculoskeletal and Skin Diseases. Pimples range in size from small bumps to large, deep cysts. Dead skin cells and excess skin oil causes acne. Washing does not prevent pimples and sometimes worsens them if you scrub too roughly or use inappropriate products.
Acne lesions tend to heal, while warts are more persistent, but both conditions are highly treatable. Acne treatments come in many convenient forms, like creams, washes, cleansers, wipes, lotions and pads, most of which use salicylic acid, sulfur, resorcinol or benzoyl peroxide as the primary ingredient. Drugstores and other big retailers sell these remedies. Salicylic acid is also sold as an over-the-counter wart fighter for blemishes on your hands, feet and other areas, but such products are not for facial use except on a physician's advice. Visit your doctor if you are unsure about whether a particular facial blemish is a wart or pimple.
