Extreme caution must be used when injection is performed aroud the eye. There are many challenges that need to be addressed before attempting this procedure e.g skin thickness,avoiding blood vessels,choosing the correct amount.
I personaly prefer microfat grafting. The injection must be done deep to avoid lumps,a blunt needle is better used and the injection performed in a retrograde manner to avoid blood vessels. It is important not to over inject in this area. It is always easy to add more. Some of the deformities around the eye could only be treated with some sort of injection e.g hollowness of the upper eye.
