**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.
**Simple Prevention Tips**
To reduce the risk of worsening or spreading the rash, it’s important to wash your hands thoroughly, avoid touching the affected area, change your pillowcases frequently, and use separate towels. It’s also recommended to avoid heavy cosmetics, perfumed skin products, and steroid creams without a doctor’s prescription. Even toothpaste, saliva, or constantly licking the area can irritate the sensitive skin around the mouth.
The most important message is that a rash like this should not be ignored, especially if it’s crusted. It can be treated, but the appropriate therapy depends on the cause. A healthcare professional or dermatologist can properly evaluate it and help prevent scarring, spreading, or recurring outbreaks.
