I had a cafe au lait birthmark excised. After taking the stitches out the doctor gave me TNS Recovery Complex (face cream derived from foreksin of circumcised babies) to put on the scar so that it can "scar well." is It cost around $180 and it is much cheaper online. I want to know what would work on the scar. Would this work? Is there something cheaper from the local pharmacy? I feel like I was tricked into buying it.
