Hi Tracy

I read a article a few days ago that somewhat relates to the question you asked, because I know of no scripture pertaining to cosmetic surgery, I can`t give you a educated answer, but you may find this commentary enlightening.
On Tattoos & Body Piercing
A few weeks ago, someone sent me an email inquiring about a Christian perspective on tattoos and body piercing. They had heard a few answers from others, but they weren't very satisfying. I have often felt that way. Too often the church gives a simplistic answer to a complex question, and in so doing, we teach our children not to think but simply to obey. Just saying something is wrong, or quoting one verse from the Bible out of context as our proof text is not really adequate. Our children deserve better. (Lest I be open to the same charge of proof-texting, please note that the Scriptures mentioned here are only a sampling of many which support the principles discussed. Those who wish should have no trouble finding many more.)
I think we are skating on thin ice whenever we try to say something is bad that the Scriptures don't speak to directly. Briefly, the Scriptures only have a couple of references to marks on the body (e.g. the mark on Cain, the mark of the beast, etc.). and only one specific reference to tattoos (Lev. 19:28). In context, the verse is discussing idol worship, but the grammar of the sentence seems to indicate that tattoos of any kind are forbidden. Without getting into a discussion of which Old Testament laws are still binding on Christians and which are not, it would seem prudent to avoid tattoos altogether.
Earrings and nose rings are both mentioned in Scripture, but we don't know much beyond that. Did they wear them in both ears? How many did they wear in a row? Did both men and women wear them? Bangles and ankle chains are also mentioned, but again with no details. They are nowhere condemned in Scripture, therefore we must not pretend that it is Christian to wear them or not wear them. (Those who would quote 1Peter 3:3, should note that it does not forbid the wearing of jewelry; rather, it says that a woman's beauty should not come from these things but from a gentle and quiet spirit.)
In my view these things are essentially matters of taste, style, and culture. This doesn't mean that we can't take a stand for or against, but we should do so on the basis of Biblical principles rather on the basis of Biblical commands. This forces us to think a bit more deeply, but ultimately our children will be better equipped for living. Once children learn the principles, they can then apply them to any number of situations.
First, the principle of modesty (or humility) says that I will not do things which will call undue attention to myself. (Hey, everybody, look at me!) See Philippians 2:3 and 1Peter 5:5.
Second, the principle of deference says that we should be sensitive to the issues which concern others. When in Rome live as the Romans. Eat meat offered to idols unless it offends someone else. If it does, then skip it. See 1Corinthians 8
Third, the principle of honor says that we are to honor parents, government, elders and other rulers and abide by their standards. Thus, while children live at home, they must commit to honoring their parents. While at school they agree to respect the standards of the school. That means more than just doing what they are told, but rather living in such a way that they truly demonstrate their respect for those in authority even when they are not around. See Romans 13:1,7
Fourth, the principle of taking care of one's temple says that we should not do anything which might cause harm to our bodies. Scarring, mutilation, rings in the mouth, tongue, breast, etc. are unhealthy, and therefore are not acceptable for Christians. 1Corinthians 6:19
Fifth, the principle of being a light to the world says that we should always be prepared to witness. Will this help or hinder? The question needs to be asked and answered honestly. (In some circumstances, it might help! For example, when I was at Bible college, I argued successfully that my beard helped me in my coffeehouse ministry to street people.) See 2Peter 3:15
While the principles are timeless, the applications change with the culture. For example, certain kinds of body piercing will always be unhealthy and therefore should be avoided. But others are a matter of cultural acceptance. They should be avoided perhaps at certain times and places, but may be acceptable at others. Teach your children to be wise and discerning and to live by principle. Help them to discern between those things which are wrong and those things which are not wrong but, nevertheless, are not acceptable, approved, helpful, wise, etc. Modesty, deference, honor, stewardship, and witness, however, are always in style.
