Candidiasis, also known as yeast skin infections, tends to affect skin that comes in contact with skin. You might see the infection in your underarms, under your breasts, in your neck, in your belly, or even in your groin area. However, yeast infection on the face is also possible.
Although some rashes and blemishes on your face can be attributed to hormones, sometimes they are caused by a yeast infection.
People who take antibiotics are at risk of developing oral thrush, a yeast infection that affects the mouth’s moist lining and sometimes the corners of the mouth (angular cheilitis). When it occurs in adults, it can also be a sign that they have HIV or other issues with their immune system.
