Injectibles can help a great deal in terms of instant feminization. Dr.s can augment cheeks, chins, give a brow lift type effect and help other facial areas. I have used Radiesse, Sculptra, fat transfer & silicone (performed by a doctor). They all have different pros/cons. The benefit is that you can achieve a mild-moderate feminizing effect for a couple of thousand max. The bad part is that all fillers are temporary and need to be re-upped. Well, the silicone is not temporary, but very few MDs will use it these days.
