There are several methods for you to make your droopy eyes better, but not totally droopy eyes free.
But before that I suggest you not to get botox anymore, because that's not a sustainable method, though I'm not sure what your goal is. I guess it's the weight-losing stuff. There is another way to make your face be more smooth and compact, such as exercise or keeping on health diet.
Okay let's get back to the eyes problem, you need to use some Eye gel to strengthen the skin collagen fibre and anti-oxidation, anti-wrinkle, anti-aging ,for be the emergency treatment.
Once you recover a lot, try to do more exercise and eat more healthy food like fruit and vegetables and honey which can contribute to your skin and immune system.
