Are blisters near the mouth always herpes? For education purposes, this thread shares what else could be causing those bumps and how to spot the difference.
🔑 Let’s start with Herpes
Cold sores are one of the most common causes of blisters around the mouth.
These are caused by the herpes simplex virus (HSV-1).
They are usually painful, filled with fluid, and can reappear in the same spot over time.
They often start with a tingling sensation before the blister forms, and while they are very common, they are not the only cause of blisters in this area.
🔑 Impetigo
Impetigo is a skin infection caused by bacteria like Staphylococcus or Streptococcus.
It typically appears as red sores or blisters that can burst, leaving behind a yellow, crusty scab.
This condition is highly contagious and often affects children, but adults can get it too.
Unlike herpes, impetigo is caused by bacteria and requires different treatment, usually with antibiotics.

🔑 Angular Chelitis
Angular cheilitis occurs when the corners of your mouth become inflamed, leading to cracks, redness, and sometimes small blisters.
This condition can be caused by a fungal infection, nutritional deficiencies, or excessive drooling.
Unlike cold sores, angular cheilitis tends to affect both corners of the mouth and is often mistaken for chapped lips.
🔑 Allergic reaction
Blisters around the mouth can also be a result of allergic reactions.
Common triggers include certain foods, lip balms, toothpaste, or even medications.
These allergic reactions can cause irritation, swelling, and blisters. Identifying and avoiding the allergen is key to preventing them from recurring.
🔑 Hand, Foot, mouth diseases
Hand, Foot, and Mouth Disease is a viral infection that is more common in children but can also affect adults.
This condition causes blisters to appear not just around the mouth but also on the hands and feet.
The blisters in this case are usually not painful but can be itchy and uncomfortable.
If you have blisters around your mouth that don’t go away, are particularly painful, or keep coming back, it’s important to see a doctor
