Dr. Jay G. Barnett in NYC has been using medical grade liquid silicone for over 40 years and and he says the FDA has approved. I'm a HIV patient and i wanna use liquid Silicone as a facial filler. I called Dr. Barnett office and I spoke with Sarah. Sarah told me after paying $150,DR. Barnett will answer all my questions. So, I asked Sarah if Dr. Barnett would give me ANY papers attesting what kind of Silicone he is putting on my face.She said NO and it's better if i don't show up. Strange no ?
