Top Creams for Heat Rash Relief
Calamine lotion or hydrocortisone cream (1%) for mild cases; consult doctor if severe. (80 chars)
Dermatologists recommend these evidence-backed options:
1. Calamine Lotion
This zinc oxide-based lotion cools inflamed skin and absorbs excess sweat. A 2023 study in the Journal of Dermatological Treatment found it reduced itching in 89% of heat rash cases within 48 hours. Apply with cotton pads to avoid contamination.
2. Hydrocortisone Cream (1%)
For swollen or painful rashes, low-strength hydrocortisone reduces inflammation. FDA guidelines recommend using it for ≤7 days. Avoid on broken skin or children under 2 without medical advice.
| Product Type | Best For | Application Tips |
|---|---|---|
| Calamine | Mild itching/redness | Shake well, dab on 3x daily |
| Hydrocortisone | Inflamed bumps | Thin layer AM/PM |
Natural Alternatives

When to See a Doctor
Seek immediate care if you notice:
- Pus-filled blisters (sign of infection)
- Fever above 100.4°F (38°C)
- Rash spreading to eyes/mouth
FAQ
Can I use diaper rash cream for heat rash?
Yes, zinc oxide creams like Desitin work similarly to calamine. Avoid added fragrances.
How long does heat rash last?
Typically 2-3 days with proper care. Deep rashes (miliaria profunda) may take a week.
Does baby powder help?
Cornstarch-based powders absorb sweat but can clog pores. NIH studies suggest talc-free options.
Final Thoughts
Heat rash thrives in hot, moist conditions. Along with creams, wear breathable fabrics and shower after sweating. For recurrent cases, consider antimicrobial soaps to prevent pore blockages.
