      Dr Grekin is awesome. His laser procedure on my lips 10 years ago changed my life. Yesterday he confided in me that he wasn't sure if my procedure would work because my lips were so badly damaged. My husband, a dental surgeon, also doubted my procedure could work. To Dr Grekin's credit, he tried his best & my lips look great.
