Having personal experience with laser hair removal lasers and treatments I want to warn you to think very carefully about doing laser hair removal on the face because you're a female!!! LHR works on thick, dark dense hair. And majority of women with facial hair problems do not have coarse and dense enough hair for laser to work. One of the major side effects for females that do LHR on the face is something called "Laser Induced Hair Grwoth." It basically stimluates more hairgrowth instead of killing hair when the hair is fine, villous or when women have hormonal embalance or a condition called PCOS. This stimulation can happen after a single treatment or later after a course of treatments. Do not!! use lasers that are used for killing hair on your entire face, especially on areas where you don't have hairgrowth!! My advice is to go the electrolysis route for your face. It maybe a little slower and more expensive, but you will save too much stress and more $$ clearing the laser induced growth with electrolysis down the road.
As for laser and acne. The laser machines used for acne treatment don't do a lot. When I had laser hair removal on my chest, the heat from laser would zap away my slight body acne but all that acne would return in matter of months. I had 8 laser hair removal treatments and each time the chest acne would go away and come back. So do your research and don't rush into treatments. A lot of laser clinics sweet talk people with promises and good discounts like used car salesmen. These lasers for acne are kinda like chemical peels and dermabrasion. The laser superficially might oblate the top layer of skin, and that's it.
If you want to try light based treatments for acne, I would look into Levulan-Omnilux or similar blue/red therapies. Even they are not a cure but just acne management which will require periodic treatments. I heard about the Isolaz but don't hear much talk about it.
