New York: A growing number of people are opting for a new technique known as “fat grafting” to erase signs of ageing in the face without major surgery.

The American Society of Aesthetic Plastic Surgery says more than 90,000 fat grafts were performed in 2005 and it is becoming one of the most popular procedures since it uses a person’s own fat so there is no risk of rejection. And now techniques are getting more refined.

Recently a new procedure in which the surgeon combines the fat injection with platelet-rich plasma (PRP) help the treatment’s efficacy.

Doctors say there’s not usually much bruising or swelling. And for most patients, fat grafts last for years. Although some people could need a second procedure to get the final result they want.
