Hello! I have bad wrinkling from a prior knee lift surgery. I've had eleven rounds of micro-needling and laser treatments. I don't have enough lax skin to redo the surgery, but there is some laxity on the interior of my knees. Could a little bit of skin be removed from just the interior knees to help solve the wrinkling? I've also had three Fraxel treatments to try to improve the scars. I've read that the laser treatments only garner a 10-20% improvement, if that. I didn't notice any change
