How to treat miliaria crystallina

Summer weather is characterized by high temperatures and high humidity—conditions that make heat rash (miliaria) especially common, particularly in infants and young children. Heat rash can cause pain and itching, leading to significant irritability; babies may become especially fussy and cry more frequently. So, how is miliaria crystallina (“white heat rash”) treated?

How to Treat Miliaria Crystallina

After developing miliaria crystallina, applying talcum powder (baby powder) can help alleviate symptoms. Adding Liu Shen Flower Dew (a traditional Chinese herbal lotion) to bathwater may also reduce symptoms and provide a cooling sensation. If bacterial infection of the skin contributes to the development of white heat rash, calamine lotion or other topical agents may be used for cleansing and soothing, helping to relieve itching. Anti-inflammatory and antibacterial medications—including erythromycin, cetirizine hydrochloride, and chlorpheniramine tablets—should only be used under a physician’s guidance.

If white heat rash appears internally (e.g., on mucosal surfaces), it may stem from viral infection, inflammation, or skin injury—prompting immediate medical evaluation, including dermatological examination and routine blood tests. Individuals prone to heat rash should prioritize skin hygiene: sweat should be wiped away promptly, and daily bathing with lukewarm water is recommended. Wearing loose-fitting, soft, breathable, and moisture-wicking clothing is also essential. Staying well-hydrated and maintaining regular bowel and bladder function helps eliminate internal damp-heat, thereby reducing the risk of heat rash.

In daily life, ensure adequate ventilation and a cool environment, wear loose, breathable clothing, and keep the skin clean and dry. We hope this information proves helpful.
