Lip augmentation, as with many plastic surgery procedures can be made to look very natural, it is all dependent on the amount of product that is inserted and the person performing the procedure.
Temporary fillers are the best option for a no fuss lip augmentation and wonderful natural and permanent results can be achieved with dermis fat grafting or with fat injections. Both of these procedures yield excellent results, with my preference being dermis fat grafting.
Using this method I can take tissue from a pre-existing scar or from an area of skin where a scar will be hidden, like the suprapubic area or even the groin. This can be performed under a local anaesthetic, assisted local or general or combined with another procedure.
