Pimples around the mouth can be caused by several factors, including acne, hormonal changes, contact with irritants, friction or pressure, certain cosmetics and skincare products, diet, stress, and poor hygiene.

Common Causes of Pimples Around the Mouth

• Acne: Blockages of hair follicles by oil and dead skin cells can lead to pimples. Pimples may be red, inflamed, and sometimes filled with pus. Acne often affects other areas like the nose, forehead, and chin.

• Hormones: Hormonal fluctuations during puberty, menstruation, pregnancy, or menopause can increase oil production, making the skin prone to breakouts.

• Irritants: Toothpaste, mouthwash, some foods (especially acidic or greasy ones), and lip products can irritate skin around the mouth and cause pimples or redness.

• Friction and Pressure: Frequent touching of the face, resting the phone on the chin, or wearing helmet straps can transfer bacteria and clog pores, causing pimples.

• Cosmetics and Skincare: Heavy or pore-clogging makeup, lip balms especially with wax or fragrances, and other skincare products can trap oil and irritate skin.

• Diet and Stress: Although evidence is not definitive, greasy or sugary foods might worsen breakouts, and stress can increase sebum production.

What to Do

• Maintain good facial hygiene and avoid frequent touching of the area.
• Use non-comedogenic, gentle skincare products.
• Avoid irritants like certain toothpaste and lip products.
• Consult a dermatologist if pimples persist or worsen, especially to rule out other conditions such as perioral dermatitis or oral herpes.

In summary, pimples around the mouth are typically due to acne influenced by hormonal, environmental, and lifestyle factors. Identifying and managing these causes can help reduce breakouts.
