Another possible cause is perioral dermatitis, a rash that appears around the mouth and can look like small red or skin-colored bumps. The American Academy of Dermatology explains that it can resemble an acne-like outbreak around the mouth and can also affect the nose or eyes. This condition is not the same as common acne, and using harsh acne products can worsen the irritation.
Other possibilities include eczema, contact dermatitis, saliva irritation, reactions to toothpaste or skin care products, shaving irritation, cold sores, or a combination of irritation with a secondary infection. The NHS notes that impetigo can resemble other skin conditions, such as herpes, eczema, shingles, or chickenpox, so a proper medical evaluation is important.
**Why You Shouldn’t Touch or Rub It**
When the skin is red, scaly, crusted, or sore, manipulating it can worsen the problem. Scratching or squeezing the lesions can further damage the skin, increase irritation, and spread germs to other areas. Harsh exfoliants, products containing alcohol, harsh acne creams, or overly aggressive skincare routines can also damage the skin barrier.
A safer approach is to keep the area clean and gentle. Wash with a mild cleanser or just water, pat dry with a clean towel, and avoid sharing towels, lip balms, razors, or facial products. If the rash oozes, spreads, is painful, or crusts over, it’s best to see a doctor rather than covering it with makeup or trying random creams.
**When to See a Doctor**
You should seek medical attention promptly if the rash is spreading, painful, hot, swollen, oozing pus, forming yellow crusts, or if you develop a fever. A doctor can determine whether it’s bacterial, viral, allergic, or inflammatory. If it’s impetigo, treatment usually requires prescription antibiotics. The American Academy of Dermatology states that dermatologists typically treat impetigo with topical antibiotic medications such as mupirocin or retapamulin.
