I have a very weak chin and an oblong or peanut face shape especially when I smile and my temples hollow in. I would like more of a heart shape. My wish face shape is like Rhianna. We both have big foreheads but I like how hers pans out more at the sides making the ends of her eyebrows more visible and longer. Could fillers fix that? I plan on getting a lip lift, chin filler, and my teeth fixed. I also hate my face when I smile.
