Hello, I understand your concern for the peeling brown patch in between my breasts. After analyzing your query it is evident from your query that you have the fungal infection of the breast area called as tinea which is quite a common condition in females. It is quite frequent to see these brownish spots due to sweating and folds of the skin which causes moist areas to proliferate more of the fungus or yeast. In my patients I suggest them to maintain good hygiene and wear cotton clothes to keep the area dry and sweat free. I suggest them to change the undergarments for two times a day and not to wear any synthetic garments. I also suggest all my patients with this condition to stay away from heat and humidity. In my patients I suggest them to apply an anti-fungal cream such as ketoconazole or clotrimazole for two times a day and if required then I prefer to give anti-histamine such as cetrizine for two times a day. Get well soon.
