Understanding Perioral Dermatitis — Causes, Treatment and How Hazel Clinic Can Help

Perioral dermatitis is a common inflammatory skin condition that typically appears as small red bumps, mild peeling, and irritation around the mouth, nose, or eyes. While it can resemble acne or rosacea, perioral dermatitis is a separate condition that often requires specific medical management to fully resolve.

What Causes Perioral Dermatitis?

There isn’t one single cause, but rather a combination of triggers that can contribute to the condition. The most common include:

• Topical steroid creams (especially those used on the face)

• Overuse of cosmetics or heavy moisturisers

• Hormonal changes

• Fluorinated toothpaste

• Environmental stressors, such as wind or humidity

• Imbalance of the skin barrier

It is more common in women between the ages of 20 and 45, but can appear in anyone.

How Can It Be Treated?

Successful treatment begins with a clear diagnosis. During your dermatology consultation at Hazel Clinic, Dr. Susana Fontana will carefully evaluate your skin and medical history to determine the exact cause and best treatment plan.

Treatment may involve:

• Discontinuing topical steroids and avoiding potential irritants

• Topical anti-inflammatory creams or antibiotics, such as metronidazole or erythromycin

• Oral antibiotics in moderate to severe cases

• Restoring the skin barrier with a gentle, tailored skincare routine

It’s important to avoid self-treating or switching products too frequently, as this can worsen the inflammation.
