Pseudomonas (Hot Tub) Folliculitis

Did you develop an itchy, red rash after spending time in a hot tub or swimming pool? You might be experiencing hot tub folliculitis, also known as Pseudomonas folliculitis—a common skin infection caused by bacteria in inadequately chlorinated water.

At SOMA Skin & Laser, our dermatologists offer prompt, effective care to relieve symptoms and prevent recurrence.

What Is Hot Tub Folliculitis?

Hot tub folliculitis is a skin condition caused by the bacteria Pseudomonas aeruginosa, which thrives in warm, moist environments—especially poorly maintained hot tubs, spas, pools, and even water slides.

The bacteria infect hair follicles, leading to a rash that can be itchy, uncomfortable, and cosmetically concerning.

Key Symptoms

  • Red, itchy bumps or pustules appearing within 6–48 hours after exposure

  • Rash concentrated on areas covered by a swimsuit (traps moisture and bacteria)

  • Possible burning, stinging, or tenderness

  • Occasionally accompanied by low-grade fever or malaise

  • Rash typically resolves in 5–10 days but may require treatment

Who Is at Risk?

You may be at higher risk if you:

  • Soak in hot tubs or whirlpools frequently

  • Swim in poorly chlorinated pools or water parks

  • Wear tight-fitting swimwear for prolonged periods

  • Have sensitive or broken skin

  • Are a child or teen (more common in younger people)

Diagnosis at SOMA Skin & Laser

Our board-certified dermatologists diagnose hot tub folliculitis based on:

  • Clinical appearance and exposure history

  • Bacterial culture (in atypical or persistent cases)

  • Evaluation for secondary infection or other types of folliculitis

Treatment Options

In many cases, hot tub folliculitis is self-limiting, but treatment can speed up recovery and reduce discomfort.

1. Topical Treatments

  • Antibacterial cleansers (chlorhexidine or benzoyl peroxide)

  • Topical antibiotics like mupirocin for localized lesions

  • Anti-itch creams (mild corticosteroids or antihistamines)

2. Oral Medications

  • Oral antibiotics (e.g., ciprofloxacin) in moderate or extensive cases

  • Typically reserved for persistent or widespread infections

3. Supportive Care

  • Cool compresses

  • Avoiding tight clothing and re-exposure

  • Gentle skincare to support the healing barrier

Prevention Tips

  • Bathe or shower immediately after hot tub or pool use

  • Limit time in hot, moist environments

  • Wash swimsuits thoroughly and change out of wet clothes promptly

  • Only use well-maintained and properly chlorinated spas and pools

  • Avoid shaving before entering hot tubs (can increase risk)
