I have deep lines on the edges of my mouth commonly referred to as marionette lines. One is so deep that it is constantly chapped and drinking liquids leak from it. My PCP referred me to a dermatologist for possible collagen inj to the site to plump it up. The dermatologist insisted this product was the only thing that would fix it. It was $599. I went for it desperate to not be a drooler. After receiving the first painful round for 599 I looked in the mirror and saw no change to the deep lines, she assured me a second round for $499 would work. No other alternative was offered and the doctor was confident in the outcome. Didn't work, not happy and to add insult to injury, I wasn't given the $100 discount for the second round of Bolotero. I feel totally taken advantage of. Beware.
