Can Botox and fillers help with nasal flaring when smiling? (Photo)

I have a relatively small nose with a bulbous tip. I don't mind the shape of my nose but I hate how I look when I smile or even talk sometimes. I included pictures so you can have a better idea. I do notice that I have somewhat deep nasolabial folds when I smile so I'll ask for fillers there specially after I lose some weight. However do you think I can benefit from Botox or fillers for the nose? Where should I ask for them to be injected? Any other nonsurgical options to reduce nasal flaring?
