How to steer clear of psoriasis in your skin folds

Common symptoms and precautionary measures

The skin in skin folds such as the armpits and under the breasts is more delicate and thinner than in other areas. Rubbing and sweating can be a cause of frequent psoriasis irritation.

It can get hot and damp where the skin has less contact with the air. This increases the likelihood of yeast and fungal infections, especially in areas where you sweat more, such as the armpits, under the breasts, and in the groin and crotch area.

As often as possible, try to wear loose, comfortable clothing. The best materials are cotton or poly-cotton mixes

Taking precautionary measures

Try to wear loose, comfortable clothing.1 The best materials are cotton or poly-cotton mixes. Women may also want to avoid wearing bras with underwires as these may increase perspiration.

Keep dry and comfortable

For psoriasis in the groin and crotch area – around the genitals, anus and between the buttocks – it is advisable to have an additional daily wash in warm summer weather. Afterwards, remember to dry your groin and buttock creases thoroughly.

You should wear comfortable cotton underwear and avoid tight jeans and trousers. It is best not to wear synthetic materials next to the skin as they cause sweating. For men, boxer shorts are better than briefs as they allow air to circulate.
