Our forehead muscle is pretty much the only muscle in our face that holds up our brows. Therefore, you should always see a physician, who is well versed in facial anatomy in order to get a proper aesthetic outcome from Botox injections. It sounds like your forehead was overinjected, resulting in "dropped" brows, because there is nothing pulling them up anymore. This lower brow position is responsible for puffy and heavy-appearing lids. Fortunately, the effects of Botox are temporary and you should expect a full resolution of your symptoms in 3 to 4 months. Please see a Board-Certified Dermatologist or Plastic Surgeon in the future to achieve an optimal outcome.
I am sorry that you decided to get Botox injections from an unqualified person. Bruising is not common with Botox as the needle is so fine and facial veins are usually visible, so that an experienced injector would notice them.Since the injector is not a physician, do you even know if it really was Botox. Fotox( fake Botox) may have been used.As such, it is difficult to give anymore comments. best of luck.
I would definitely hold off on any more Botox. It is unusual to have swelling and bruising 8 days after injection. To be safe I would see a physician with experience to make sure that there is not something else going on like an allergic reaction. Good luck.
Most likely the Botox was placed too low and so your eyelids and/or eyebrows have fallen. If it truly is just your eyelids, a physician can prescribe eyedrops that will help elevate the eyelids quicker than just waiting it out. However, most often it's a combination of eyebrow and eyelid ptosis when this happens, and so the only thing to do about that is wait it out. I would agree that more injections from this person may not be the best solution. If possible, return to your prior injector whom you were happy with. As you've learned - the hard way! - is that injections are an art and some people just aren't artists.

It will get better with time. Botox lasts 3-6 mths so you should see an improvement on a weekly basis. The non physician injector may be less expensive but you may get what you pay for. Consult with a Board Certified Plastic Surgeon.
Unfortunately, there is not much you can do. The good news is that nothing with Botox is permanent. Your face will go back to normal as the Botox wears off.
