Hi, I have these skin rashes on both my underarms and under my right breast above the tummy. It's not itchy or watery. I have this for a long time. Sometimes it will be bright in color like brown dark spots. After that, it will fade off and rashes will be present in light color. But it hasn't disappear completely. I used some pigmentation cream from the pharmacy and that doesn't help I have these rashes for more than 2 years. Is this something serious? I asked my physician once last year and she said it will go off. But didn't prescribe me any cream. I still have these and I don't know what it is. Attaching pictures. What helps to fade these off?
