There is no suggestion that menopause leads to rashes, but as estrogen affects skin condition, alterations in the skin are to be expected when estrogen fluctuates during such processes as menopause. Dryness from estrogen loss can make skin more vulnerable to irritation, reports Healthy Women.
Women in menopause who use estrogen therapy have skin that is less dry and thicker than their peers who do not supplement with that hormone. Skin dryness can cause irritation, especially where underwear touches the skin. Estrogen has an effect on the way in which wounds heal, and lower estrogen levels may lead to irritation. Women also have a higher likelihood of developing rosacea, a condition that causes scaly skin on the face and a red rash. While rosacea affects women in their thirties and forties, it generally is not connected to estrogen, notes Healthy Women.
Menopause thins women's skin, which can lead to bruising and tearing. A possible cause for this thinning is loss of estrogen. The normal wrinkling and loosening of skin that come with age, though, have more to do with environmental damage and exposure to the sun than with diminishing estrogen. Women suffering from a rash could have many different contributing causes, ranging from stress to an allergic reaction, so an appointment with a physician is the best way to get a precise diagnosis, according to Healthy Women.
