Sometimes it’s obvious when Hollywood stars go under the knife or get injections – but not always!

From flattened foreheads to terrible trout pouts, stars have taken injections to the extreme, but there are several others who are indulging in injections that we don’t even know about! Breaking Celebrity News exclusively spoke to Beverly Hills Plastic Surgeon to the stars, Dr. Garo Kassabian of Lift MD Aesthetics, who revealed the secrets to his clients’ (of course he can’t tell us who they are!) flawless faces and how he keeps them looking totally natural and appearing surgery and injection free!

Breaking Celebrity News: What are the biggest mistakes you have seen on celebrities with Botox/fillers?

DR. KASSABIAN: Too often, people think that more looks better.  With Botox and fillers, the key is to start off doing it little by little so that it looks more natural and allows for you to have your natural facial expressions. I pay close attention to each individual’s own areas of concerns and target those areas to give them a refreshed look.  However, it is important to note that injectables are not a substitute for surgery. They are used to compliment surgeries targeting specific areas of concern or to be used for those that are just experiencing the early stages of aging and may not be a candidate for surgery. Every person is different and some may benefit more from an eyelift or facelift.

Breaking Celebrity News: Are there a lot of celebrities who claim they have never used Botox that you think really do?

DR. KASSABIAN: My belief is that the best plastic surgery is where you cannot tell anything has been done.  This is the same for Botox and fillers. Botox and fillers are used for fine lines and wrinkles and adding volume. With the right technique and skills, a patient can look more youthful

without any of the usual telltale signs. I am sure there are a lot of celebrities not talking about it, but that is my job to make sure they don’t have to.
