How Can I Make my Face Look Softer? (photo)

As others have mentioned, tapering your jawline and softening the angles of your jaw by receiving masseter reduction with Botox, will help to feminize the lower third of your face.  An area that will also benefit from Botox is your periorbital or brow/eye area.  Your brows are showing some heaviness along with your upper lids.  Botox can be used to lift your brows and give you a slightly more feminine shape.  

Botox injected in your masseter muscle will relax it so that it doesn't look so clenched and bulked up. This will have a definite feminizing effect on your face. Botox can also lift your brow slightly, which will make your eyes look larger. Botox can also be used to relax the muscle that is drawing your nose down slightly, though it will do nothing to sharpen the tip. If the bulk under your chin is caused by fat, not muscle, Kybella is a terrific way to get rid of it for good. Finally, as mentioned by others, hyaluronic-acid fillers can even out the troughs under your eyes and replenish volume in your temple to produce a more flattering curve to your face. Please consult a board-certified dermatologist who is expert in Botox and dermal fillers.

Based on the photo's you've provided, I don't think a "liquid rhino" will help soften your look. Consulting with a well-trained and reputable provider in person however may give you some options...often femininity comes from within!
