Acne skin

Due to female hormone imbalance, I have pustular acne and just red acne on my chin.

Will it go away quickly if I get an anti-inflammatory injection? Or should I get a Capri laser...? Or extraction..?

I have an important appointment, so how many days in advance should I get the procedure done so I can go out with a bare face?

And additionally, is it possible to treat back acne (shoulder area) as well as facial acne?
