I had this patch with slightly dry skin, no itching, on my pubic area( almost half of the whole area under the hair and a small part going toward the
crease of the thigh ). I am a female 44 years old and had it for months.
It was just a tone darker than my skin tone, and I thought it was a hormonal pigmentation change. Today, after coming from the gym, I saw that it became dark pink, red. At night it became a bit lighter again, but still more color than before.
