26F and skin is in great shape, what would you recommend for perioral mounds? (Photos)

I'm 26F and skin is in great shape. I have always had this odd area but it didn't used to be so noticeable. As my face has been maturing this odd area has become more obvious. I do have a slightly recessed jaw and an underbite, but when I move my jaw forward the area looks the same. When I smile it seems to be camouflaged more. What can I have done here? I've been recommended cheek filler and filler under the area but I am worried about migration.
