- Chemical exposure: Exposure to certain chemicals can cause blisters to form on the skin. Examples include bleach, detergents, and other harsh cleaning agents.
- Allergies: Allergic reactions to certain substances, such as poison ivy or latex, can cause blisters to form.
- Infections: Certain infections, such as herpes simplex virus or chickenpox, can cause blisters to form on the skin.
- Medical conditions: Some medical conditions, such as eczema or pemphigus, can cause blisters on the skin.
- Medications: Certain medications, such as antibiotics or diuretics, can cause blisters to form as a side effect.
Of note, blisters can also be a symptom of more severe conditions, such as autoimmune disorders or skin cancer. If you have a painful blister that does not heal or is accompanied by other symptoms, it’s important to seek medical attention.
