Can you have surgery done to a skin graft to make it look better?

Scars are many and varied, and it is impossible to say for sure in your situation whether or not further surgery will make a skin graft look better or worse without examining it. I would suggest seeing your GP and raising the concern with them. Keep in mind that any further surgery is likely to be classed as 'elective/cosmetic', the cost of which you are likely to be entirely responsible for.

There are, however, a range of products out there designed specifically to make these things less conspicuous. I am assuming it is the redness/scarring that is bothering you, so you may look for products on the market designed to reduce the appearance of scars from Caesareans or stretch marks. Your local pharmacist will be able to help you find a cheap, off-the-shelf product perfect for this.

Good luck! And keep in mind that we're our own harshest critics. Assuming this is about you, my bet is that it doesn't look anywhere near as obvious to everyone else as it does through your eyes!
