The following may be all that you need if the condition is mild. They may help in addition to other treatments in more severe cases.
-If you find that soaps irritate the affected skin, use a bland soap substitute such as an emollient (moisturizer) ointment or cream.
-If possible, avoid triggers which can make things worse such as heat or spicy food.
-If you have armpit sweating:
Try using normal antiperspirants regularly. (Note: there is a difference between antiperspirants and deodorants. Antiperspirants reduce the release of sweat, deodorants mask unpleasant smells. Sweat does not have a smell. It is only sweaty clothes that are not changed that may become smelly.)
Avoid clothes that more easily show up sweat marks. As a rule, white and black coloured clothes are less noticeable when wet than other colours.
Wear loose clothing under the armpits. Avoid clothes made with man-made fibres such as Lycra and nylon.
-Consider using dress shields (also known as armpit or sweat shields)
