The area is often moist from normal vaginal discharge, sweating and in some women, incontinence. The combination of being close to the germs from the anus and being moist increases its risk of being infected. This is particularly so during the menopause when skin pH rises leading to less antimicrobial defence of the skin. Further, lipid production is reduced after the menopause which slows the healing process.
