Is fat transfer an effective method for treating smile lines and smokers lines?

There are two different lines that form on the face. The one type or line represents a break down of the supporting layer of the skin resulting in a sharp line. The smokers or lipstick lines are an example of this type of line. Fat in my experience , even with the micro fat is too large to place in the line. I have placed fat/stem cells under the lines with plus minus success.   The second lines are actually furrows. These represent a loss of volume in the face. Fat can be a nice treatment for these areas.

It most certainly is. These are mainly caused by volume loss and fat is the main tissue that wastes with time.  You have to be careful with the smokers lines though because you don’t want to have too full of an upper lip.  Laser or radio frequency heat delivery also does wonders for smokers lines. 
Hope this helps,

Best of luck,

Fat transfer (the gold standard) or filler is an effective component to fill lip lines. In addition, Botox or Dysport can be used to slightly relax the muscles we use to pucker lips, and laser treats the etched in lines.
