The eyebrows .. are you using the same texture for the bum map as you are using for the skin texture itself? Are any eyebrow transparencies also made from that skin texture? Which part are you trying to get rid of? The "embossed" looking part or the hair part? The 'embossed' looking part is coming from your skin head bum map. If it does not match up with the eyebrows you are using or with the eyebrow transparency map then it will show up.
