I am scheduled to have under eye/tear trough implants. I'd like to know, between silicone and porex, which would get better results and how do they feel? Will They bother me or just sit on the bone like fillers do? I tend to sleep on my stomach. I know silicone is easier to remove. I do not want to know if I should have them or not as I have seen my surgeon's results which are gr8 n what I want. Thank you!
