Detailed answer

1. Identify the cause of the skin rash: Determine if it is due to an allergic reaction, irritants, infection, or other factors.
2. Stop using any new products: If you have recently started using a new skincare product, stop using it immediately in case it's causing the rash.
3. Keep the area clean and dry: Gently wash the affected area with a mild soap and warm water, then pat it dry.
4. Avoid scratching: Scratching can worsen the rash or lead to infection. Use a cold compress or calamine lotion to soothe the itching.
5. Apply a topical treatment: Use an over-the-counter hydrocortisone cream or ointment to relieve inflammation and itching. For severe or persistent rashes, consult a dermatologist.
6. Follow self-care measures: Wear loose, breathable clothing and avoid excessive heat or sweating. Stay hydrated and maintain a healthy diet. If the rash persists or worsens, seek medical attention.
