Impetigo is a common and highly contagious bacterial skin infection that primarily affects children but can also occur in adults. It is characterized by red sores, blisters, and honey-colored crusts, usually around the nose and mouth.
Treating impetigo promptly is crucial to prevent its spread and speed up healing. One of the most effective treatments is topical antibiotic creams.
In this post, we’ll review the 5 best antibiotic creams for impetigo, discuss their benefits, and answer frequently asked questions to help you make an informed decision.
What Is Impetigo?
Impetigo is a superficial skin infection caused by bacteria, leading to red sores, blisters, and crusted lesions. It is highly contagious and spreads through direct contact with infected skin or contaminated objects. There are two main types:
-
Non-bullous impetigo – The most common form, causing small blisters that burst and form golden crusts.
-
Bullous impetigo – Less common, characterized by larger fluid-filled blisters that take longer to burst.
What Causes Impetigo?
Impetigo is caused by:
- Bacterial infection (primarily Staphylococcus aureus and Streptococcus pyogenes).
- Skin injuries (cuts, scrapes, insect bites).
- Poor hygiene.
- Close contact with infected individuals.
- Warm, humid climates that promote bacterial growth.
Why Treat Impetigo?
If left untreated, impetigo can:
- Spread to other body parts or other people.
- Lead to complications like cellulitis, scarlet fever, or post-streptococcal glomerulonephritis (a kidney condition).
- Cause scarring if sores are picked or scratched.
Using an antibiotic cream helps eliminate bacteria, speed up healing, and prevent further infection.
