If you are thinking about cosmetic surgery to help you stay looking younger, here are some great resources to help you find out more about what is involved.
WEBSITES
The best websites to learn about cosmetic surgery, as a rule, are not the clinics that make money from it or from sites that advertise it but from government information sites that have no vested interest in you having the surgery.
Here is a good US government website for learning about plastic surgery.
http://www.nlm.nih.gov/medlineplus/plasticandcosmeticsurgery.html
You can find printable information here from the US Department of Health and Human Services too
http://healthfinder.gov/docs/doc07932.htm
Also look at the website of the American Society of Plastic Surgeons
http://www.plasticsurgery.org/
And the American Academy of Cosmetic Surgery
http://www.cosmeticsurgery.org/
The main government site for information about plastic surgery in the UK is
http://www.nhs.uk/Conditions/Cosmetic-surgery/Pages/Introduction.aspx
and the equivalent site to plasticsurgery.org in the UK from the British Society of Aesthetic Plastic Surgeons
You will get a good introduction into the various procedures and considerations on these sites. And you can go on and research your specific questions from there.
There are also some general, well regarded medical sites that have information on cosmetic surgery, though these are more likely to be advertising funded or looking for business, so check out a few and keep an open mind as you view the information on sites like these
WEB MD (http://www.webmd.com or http://www.webmd.boots.com/ in the UK)
This page is a good starting point there

MAYO CLINIC (http://www.mayoclinic.com)
Their article on what to know before cosmetic surgery is a good one
http://www.mayoclinic.com/health/cosmetic-surgery/SN00006
As for specific facial cosmetic surgery, the website of the American Association of Oral and Maxillofacial Surgeons is useful, see
