Can my upturned nose be fixed? I look like a pig and have already had two surgeries! (Photo)

Hello and thank you for your question. In general, improvement is possible and the technique used depends largely on the surgeon's experience and preference. For my part, I find that rib cartilage grafts are a reliable method to sustain the lengthening. It creates a firmer tip but most patients seem comfortable with it.  From the photographs I assume that the skin graft was for the lining of the nose to help with the lengthening, which is an established technique. It would be possible to evaluate your goals in a computer simulation which provides more clarity about the potential surgical plan.

Main problem of your nose is upturned nasal tip with visible nostrils.
Correction is possible, even though it is not a simple surgery. With ear
or septal cartilage, upturned tip can be elongated effectively.
Good result is expected if the surgery is done by experienced rhinoplasty surgeons who has performed many revision rhinoplasty surgeries. 

All revision rhinoplasty cases are more complicated and risky than primary cases. The shape of the nose is the shape of the architecture. Cartilage and bone under the skin is what is usually modified at the time of revision rhinoplasty. Why a skin graft was used on you nose is of great concern. You need a consult with a surgeon who regularly performs revision rhinoplasty.
