i am 31 years old and have had horrible hollows under my eyes ever since i can remember. of course since i'm not getting any younger they wern't getting any better plus in that certain horrific lighting i could see the hollows were very uneven, one side was worse, the other side went down further. I was scared to death of getting any type of injections because of the risks/side effects. well after several years of hearing "you look tired" "you look sick" "didn't you get any sleep?" etc. i finally decided to go for it last friday which was 3 days ago. now i understand everyone is different but wow, i had no bruising and no swelling that i could see. she injected it deep onto the bone. she used half a syringe. although i probably could've used more we both agreed to leave it as is for now and if i wanted in a couple weeks, she could add more. the hollows are no where near as pronounced as they were. i will definitely be doing this again but i'm hoping the results will last for a long time.
