What It Is

Defining Sweat Rash (Miliaria)

→ Sweat rash, medically known as miliaria, is a skin condition caused by blocked sweat ducts, leading to sweat leakage under the skin.

→ It occurs most often in hot, humid climates, during intense exercise, or when sweat glands are immature (as in infants).

→ Korea, with its humid summers, frequently sees patients—especially babies, children, and outdoor workers—seeking care for miliaria.

Types of Miliaria

• Miliaria crystallina → Clear, tiny blisters without inflammation; common in infants.
• Miliaria rubra (prickly heat) → Red, itchy bumps with a prickling or stinging sensation.
• Miliaria profunda → Rare, deeper form causing firm, skin-colored bumps; usually in adults after repeated episodes.

Key Characteristics

• Small red or clear bumps in clusters on the skin
• Appears in sweat-prone areas (neck, chest, back, armpits, groin)
• Itching, burning, or prickling worsens with heat
• More common in infants and children, but also affects adults in hot environments

Why It’s Done

Main Reasons for Seeking Care

➡ Symptom Relief – Prickling, itching, and discomfort interfere with sleep and daily life.

➡ Prevention of Infection – Scratching can cause bacterial infection of sweat ducts.

➡ Infant Care – Parents seek care for babies who are vulnerable to severe miliaria.

➡ Workplace Comfort – Outdoor workers and athletes require management to function in heat.

➡ Cosmetic Concerns – Visible red bumps may be embarrassing.

Alternatives

Non-Medical Options

• Cooling Environment → Staying in air-conditioned or shaded spaces.
• Loose Cotton Clothing → Reduces sweat and friction.
• Frequent Cool Showers → Helps unblock sweat ducts.
• Avoiding Heavy Creams → Thick ointments may clog pores further.

Medical Alternatives

→ When simple cooling isn’t enough, treatments may include:

• Calamine Lotion → Soothes itching.
• Mild Topical Steroids → For severe inflammation.
• Antihistamines → Relieve intense itching.
• Topical Antibiotics → If secondary infection develops.

Preparation

Before Care in Korea

➡ Dermatology Visit – Doctors assess severity and confirm diagnosis (to distinguish from eczema or allergies).

➡ Medical History – Information about environment, clothing, and recent heat exposure.

➡ Lifestyle Assessment – Work, exercise, or childcare routines reviewed.

➡ Patient Counseling – Explanation that miliaria is temporary but may recur in hot weather.

➡ Skin Care Planning – Adjustments to daily skincare, bathing, and clothing are discussed.

How It’s Done

Standard Miliaria Care in Korea

1. Environmental Control
→ The cornerstone of care is cooling.

• Air-conditioning or fans to reduce heat and humidity
• Frequent breaks in shaded areas for workers
• Babies kept in light clothing with breathable fabrics

2. Skincare and Cleansing

• Gentle lukewarm showers to remove sweat
• Avoid oily or occlusive creams that block pores
• Use of hypoallergenic, fragrance-free cleansers

3. Topical Treatments

• Calamine lotion or zinc oxide creams for soothing
• Low-potency corticosteroid creams for severe itching (short-term only)
• Topical antibiotics (mupirocin, fusidic acid) if infection suspected

4. Oral Medications

• Antihistamines for itching, especially in children with sleep disturbance
• Rarely, oral antibiotics if widespread infection occurs

5. Specialized Pediatric Care
→ In infants, Korean pediatric dermatologists emphasize:

• Frequent clothing changes to keep skin dry
• Avoidance of excessive swaddling or overheating
• Close monitoring to prevent complications

6. Cosmetic Dermatology Support
→ For adults with recurrent miliaria and pigmentation:

• Laser therapy or skin brightening programs to reduce post-inflammatory marks
• Counseling on long-term skincare to reduce recurrence

Recovery

Immediate Recovery

• Symptoms improve within days once cooling and proper skincare begin.
• Itching and burning resolve as sweat ducts clear.

Long-Term Recovery

→ With continued preventive measures, patients avoid recurrence during hot weather.

→ Infants usually outgrow miliaria as sweat ducts mature.

→ Adults benefit from skin-friendly routines and environmental adjustments.

Complications

Risks Without Care

• Secondary Infection → Scratching can introduce bacteria (staphylococcal infection).
• Worsening Rash → Untreated cases may progress from rubra to profunda.
• Chronic Discomfort → Sleep disturbance, reduced productivity in adults.
• Infant Vulnerability → Severe miliaria in babies can lead to heat exhaustion.

Risks With Treatment

• Steroid Overuse → Prolonged topical steroid use can thin skin.
• Allergic Reactions → Rare irritation from lotions or creams.
• Incomplete Relief → Without environmental control, creams alone may not help.
