Cosmetic surgery is a good method to resolve body image issues. While in most cases people can lose weight or wear makeup to appear attractive according to their own standards, in other cases people will need to have a nose job or a breast reduction to make the big difference in their lives.
Body image issues can run the gamut between birth defects at one extreme, and more frivolous desires to just look better than you do. A person who is born with some defect to their appearance ought to be able to correct it, and this is especially true of situations in which the defect has negative consequences to their health or well being. If other people choose to correct a supposed defect just relating to their feelings about how they look, they should be free to do so also. Cosmetic surgery is about the only option in both these cases, and even though there are risks, it is an elective surgery, so the risks are understood in advance.
I do not believe cosmetic surgery is a good method to resolve body image issues. People who try to resolve this problem through surgery will only ask for more surgeries in the future, until there is nothing natural about them. If a person has issues with their body image they more than likely need counseling.
No, cosmetic surgery is not a good method of resolving issues regarding one's body image. More often than not, body images issues are part of a larger self esteem issue. Therefore, having a cosmetic procedure would also repair surface issues, and would not resolve the under lying causes of the body image issues.
