After Three Laser Facials, Still See Fine Lines Around my Mouth

Lines around the mouth are called "Smoker's lines" in many parts of the country, but in Utah where we have the lowest incidence of smoking in the nation, we call them "Whistle lines".  These lines form in response to repeated contraction of the circular muscle surrounding the mouth called the orbicularis oris.  These lines can be very difficult to treat, especially when deep.  A superficial laser, the kind you probably received, is just not aggressive enough to rid yourself of these lines.  Usually you will need one, two or even three different approaches.  The first is a resurfacing treatment.  This needs to be aggressive and deep.  Options include:


Deep Erbium:YAG laser, not the superficial or even the fractionated kind, but the real deal

Dermabrasion

Deep chemical peel like a Baker's (Phenol mixed with Crotton oil and water) peel


If that doesn't do it.  Then you fill the volume deficiency.  Options include a Facelift with SMAS harvest and implantation of SMAS into the lips (not really an option for a 33 year old), Restylane or Surgisil soft silicone lip implants.  Sometimes this would include a second resurfacing treatment.  Botox is rarely an option as the results are unpredictable and with mouth motion can make you look like you've had a stroke, so be careful.  Obviously, the more aggressive the treatment, the more adverse effects you can have and the longer recovery.  So, have a long discussion about expectations with your surgeon. 

 
The fact that you had 3 laser peels means that they were very superficial peels and not likely strong enough to remove mouth lines.
Newer Combined laser resurfacing which uses both a non-ablative fractional 1540 Erbium and an ablative 2940 fractional Erbium at the same time, provides the deepest and most effective improvement in lines around the lips and cheeks.
Even with excellent laser resurfacing results around the mouth, wrinkles persist. This is because the pursing muscles of the mouth cause wrinkles. For best results small amounts of Botox can lessen these dynamic lines. Filler injections can plump the lips and help the lines.
Thus, the best treatment for lip lines is a combination of combined laser resurfacing, Botox and Fillers.

With resurfacing it takes time for the collagen to repair and help decrease more wrinkles or so most people say. In my experience, the results that you get the first month is likely the most noticeable and after that the results are more subtle with the "naked eye". When done on a more aggressive scale, you will notice more improvement more early on such as a month or two. 12 months is a little long in my opinion to notice much more difference. In terms of the lip lines, you might want to approach it more aggressively with the laser. Dermabrasion can also work wonders here.
In addition, you may want to consider plumping up your lips. A lot of the lip lines are created due to a loss of volume in the lips and the area around your mouth. Fat injections and fillers are great at creating this volume in the long and short term respectively.
