Does Active FX Do Anything to Tighten Jowls or Neck?

ActiveFx and DeepFx are fractional CO2 lasers that can repair sundamage and remove fine lines and wrinkles.  They can really tighten the skin but they will not remove excess sagging skin to the extent that a facelift or necklift will achieve.
For best results, I recommend you seek a provider who is very experienced with fractional lasers. I hope this was helpful.

Activ Fx and its companion laser, Deep Fx are fractional CO2 lasers, and are excellent tighteners for sun damaged skin of the neck, face and chest. However they do not adress excess facial and neck fat, so there will not be sufficient tightening in overwieght patients unless done following liposuction.

TotalFX (combination of ActiveFX and DeepFX) can result in skin tightening in the face and neck area. My patients have been very pleased with the degree of tightening that they have achieved with their treatments.
However, results do vary depending on many factors including on the experience of physician who is doing the procedure. For best results, I recommend you seek a provider who is well versed in use this laser device. I hope my answer was helpful.
