Short answer -- they puffiness you are experiencing is likely due to the gathering of skin above your eyelid from the drooping eye-BROW caused by your Botox treatment. This will likely last 3-4 months as the Botox wears off...A drooping eye-BROW may be encountered after Botox treatment when the brow-elevating muscle in the forehead, the Frontalis, receives too high a dose of Botox, or alternatively, if the Botox is sub-optimally placed too low in the forehead. However, in some cases, a patient may have a low set eyebrow to begin with, so if he/she were to receive any Botox to the forehead, this would increase the likelihood of a brow droop. Regardless, a droopy eyebrow can sometimes be improved with Botox injected into the outside part of the eye (the lateral aspect of the orbicularis oculi muscle) to generate a bit of a brow lift in that area -- by injecting Botox and paralyzing the orbicularis muscle that normally acts to depress the brow in that area, you may get a slight compensatory brow lift...My overall recommendations are to seek the services of an experienced physician injector. I think the key with Botox lies in truly understanding the anatomy of the injected area, and more importantly the variability in the anatomy between patients -- for brows, the forehead, and anywhere else you plan on receiving a Botox injection. This includes having a firm understanding of the origin, insertion, and action of each muscle that will be injected, the thickness of each muscle targeted, how deep beneath the skin the actual muscle resides, and the patient variability therein. As an aesthetic-trained plastic surgeon, I am intrinsically biased since I operate in the area for browlifts and facelifts, and have a unique perspective to the muscle anatomy since I commonly dissect under the skin, see the actual muscles themselves, and learn "first-hand" the incredible variability between patients -- live, "on the OR table" -- as opposed to via lectures or a cadaver dissection. For me, this helps guide where to inject and where not to. However, with that said, I know many other physicians who know the anatomy well despite not operating in that area, and get good results.Good luck.Dr Markarian
