Initially, Mr. Chinh's arms and back developed numerous tiny red bumps, and his skin became rough. He self-treated, but the itching worsened, and inflamed papules around hair follicles appeared densely, leaving many dark spots. Master of Science, Doctor Huynh Cong Tri, a specialist in dermatology and cosmetic dermatology at Tam Anh General Clinic District 7, diagnosed Mr. Chinh with folliculitis on a background of atopic dermatitis.

Atopic dermatitis weakens the skin's protective barrier, making the skin prone to dryness, dehydration, and increased sensitivity to external factors. A disrupted skin barrier, changes in the skin's microbiome, and elements like sweat, friction, or prolonged scratching can create favorable conditions for bacterial growth, increasing the risk of recurrent folliculitis. Many people mistake folliculitis for common acne, leading them to self-medicate with topical creams, exfoliation, or home remedies. However, improper treatment can lead to more persistent inflammation and lasting rough, dark skin.

Doctor Tri treated Mr. Chinh with a regimen to control inflammation, reduce itching, limit recurrence risk, and restore the skin's protective barrier. This involved oral medication, topical creams, and appropriate skincare.

After about 2-3 months, Mr. Chinh's folliculitis and atopic dermatitis stabilized, and acute inflammatory flare-ups significantly decreased. He received supportive treatment with pico laser for about 4-6 sessions, each spaced about two weeks apart. This aimed to improve post-inflammatory dark spots and uneven skin tone.

After about 4-6 months of treatment and maintenance care, Mr. Chinh experienced a significant reduction in itching on his arms and back. The inflamed papules around the hair follicles gradually decreased, and his skin surface became less rough and redder than before.

Folliculitis can appear on the arms, back, chest, thighs, or buttocks. It presents as red papules, inflamed papules, or pustules around hair follicles, sometimes accompanied by itching, burning, or a stinging sensation. According to Doctor Tri, individuals with atopic dermatitis, oily skin, increased sweating, who frequently wear tight clothing, or experience prolonged friction are more susceptible to the condition. Some cases can persist for many months to many years due to incorrect diagnosis of the cause, unsuitable treatment, or improper skincare.

To limit recurrence, patients should keep their skin clean and well-ventilated, avoiding vigorous rubbing, scratching, or excessive exfoliation. Prioritize mild cleansing products and moisturizers suitable for their skin type. Patients should also avoid self-prescribing topical medications, especially those containing corticosteroids or antibiotics. When persistent itching, recurrent rough red skin, pustules around hair follicles, or widespread lesions occur, patients should seek medical attention from a dermatology and cosmetic dermatology specialist for assessment and appropriate treatment.
