Fillers are used when the aging process causes loss of bone, fat and muscle tone in the face. It is critical to understand the underlying pathology before injecting just one area as that can often worsen other parts of the face. You likely need additional filler in the cheek bones to balance this, however it is hard to say without a picture. Always use someone who is a very good injector and you should be fine 

The risk of eye lid droop, or ptosis, occurs when the medication makes its way into the Supra orbital foramen or migrates down into the eyelid elevator muscles. I have never had this happen in my practice but it can occur with less experienced injectors. Choose someone who does this on a daily basis and you should be fine. In my office I personally do all the Botox myself.

platlet rich plasma or "prp" is an excellent way. Your blood is drawn and spun in a centrifuge. The plasma containg a high amount of platlets is reinjected into the face. This used the bodies natural repair mechanics to repair lost volume 

Accutaine is a retinol and helps the skin cells turn over quicker and therefore reduces clogged pores. It significantly improves severe cystic acne, however one pimple one month out is normal. This is why one must continue a daily skin cleansing routine
