Cosmetic surgeons are increasingly employing a new technique that could make the administration of facial fillers less painful.
The method, which is detailed in the journal Plastic and Reconstructive Surgery, combines injections of facial fillers with lidocaine, which helps to minimise pain and make the procedure more comfortable for patients.
Lidocaine is a commonly used local anaesthetic and can also be applied to the skin to relieve itching, burning and pain caused by inflammation.
Cosmetic surgery experts recently discovered that it may have another use alongside injectable facial fillers such as Restylane and Radiesse.
Surgeons at UT Southwestern Medical Centre have tested the technique and shown that as well as providing pain relief, it also allows practitioners to start the procedure without waiting for the traditional local anaesthetic to take effect.
Dr Rod Rohrich, chairman of plastic surgery at UT Southwestern, confirmed: "People are more at ease and have far less discomfort. It's becoming more of the standard."
Restylane is an injectable gel that produces volume underneath wrinkles, causing the skin to be raised and smoothened out, while Radiesse is a long-lasting skin filler that can be used to treat smile lines, furrows and scars.
