Rosacea is a skin disease that causes redness of the forehead, chin, and lower half of the nose. In addition to inflammation of the facial skin, symptoms include dilation of the blood vessels and pimples (acne rosacea) in the middle third of the face. Oral and topical antibiotics are treatments for rosacea. If left untreated, rhinophyma (a disfiguring nose condition) may result.
When you think about it, consistently reaching for your go-to face towel every day is like reusing a dinner napkin over and over again. Using dirty towels can harbor bacteria, and they can even introduce new bacteria to your skin, which may lead to more pimples. Thankfully, this doesn't mean you need to reach for a new towel every single time you wash your face, according to Dr. Melissa Kanchanapoomi Levin, board-certified NYC dermatologist and clinical instructor at NYU Langone and Mount Sinai Hospital. As long as you're truly washing off all of your makeup, you can stick to switching out your towels on a weekly basis.
No one factor causes acne. Acne occurs when sebaceous (oil) glands attached to the hair follicles are stimulated at the time of puberty or due to other hormonal changes. Sebum (oil) is a natural substance that lubricates and protects the skin. Associated with increased oil production is a change in the manner in which the skin cells mature, predisposing them to plug the follicular pore. The plug can appear as a whitehead if it is covered by a thin layer of skin, or if exposed to the air, the darker exposed portion of the plug is called a "blackhead." The plugged hair follicle gradually enlarges, producing a bump. As the follicle enlarges, the wall may rupture, allowing irritating substances and normal skin bacteria access into the deeper layers of the skin, ultimately producing inflammation. Inflammation near the skin's surface produces a pustule; deeper inflammation results in a papule (pimple); if the inflammation is deeper still, it forms a cyst.
