How effective is Serri Lifting really?

With the drastic daily temperature fluctuations during this transitional season, my skin concerns are worsening. In particular, my skin elasticity is decreasing, and looking closely in the mirror, I've started seeing fine lines around my mouth and eyes, so I'm considering a lifting procedure. However, since I am sensitive to pain, I'm looking for a low-pain type of lifting. I've heard that SERF Lifting is highly recommended, but I'm curious to know how effective it actually was for elasticity and fine lines, if there are any side effects like hollowing out the cheeks, if it is truly painless, and how much pain was actually felt.
