Suggest Remedy For Skin Ailments

I am 47 years old female that weighs 155 pounds.I had gastric bypass surgery about 12 years ago... since I lost 350+ pounds I have alot of loose skin...I have been developing boils in the creases/folds (especially in areas where hair grows) of the skin. I started getting boils after the weight loss under the loose skin of the stomach. A surgeon did a tummy tuck and removed the excess skin and that stopped the boils from occurring there. Now I am getting boils in the folds of excess skin in the creases of my legs and vaginal area. Plastic surgery isn't covered by my insurance...how can I prevent these boils?
