Detailed answer

When dealing with a skin rash in the armpits, it is important to avoid further irritation. Start by wetting the affected area with lukewarm water. Use a mild, fragrance-free cleanser, specifically formulated for sensitive skin, to gently cleanse the armpits. Avoid using harsh soaps or scrubbing vigorously as this can exacerbate the rash. Rinse thoroughly with lukewarm water and pat the area dry with a clean towel. Avoid applying any perfumes, deodorants, or antiperspirants to the rash as they may further irritate the skin. If the rash persists or worsens, it is advisable to seek medical advice from a dermatologist.
