Hello, I could be all of the reasons mentioned above as to why your filler doesn't seem to be lasting. Sometimes people are hyper metabolizers and break it down fillers much faster. Or if you work out a fair bit, this can contribute to this as well. Radiesse would be a good alternative as since it is a calcium hydroxylapatite suspension, it helps build collagen over time. Another option (depending on age, goals etc) is a product called Sculptra which helps stimulate collagen as well.
Hello, Fillers can be used in the forehead area to fill that slight hollow. You will still want to continue getting Botox to free the area, and then proceed with filler afterwards. Be sure to go to an experienced injector as you have to place the filler quite delicately in this area.
I think you're right, temples would be the icing on the cake:) Most women love the temples to be rounded outwards. It's a really nice look.
I really have not seen this go wrong. As long as your injector palpates the DAO muscle, and does not guess where they are putting it, I think you're great. It's a beautiful look, and if it was crooked by chance, it's an easy fix! I'd try it...women love it:)
You are so beautiful, as is Megan Fox:) I would consider filler for upper cheeks, and if you want to make your lower face slimmer, I'd consider botox in your masseter muscles. Have fun!
