A couple of years ago I noticed in a photo of me smiling that I have these strange ‘dents’ in my cheeks - it’s more noticeable on one side. My face looks normal when it’s rested, it really is only noticeable when I smile but it’s really annoying me, it makes me not want to smile. I didn’t have it when I was younger, it’s something more recent. I am worried that it may have been caused by previous filler I had in my cheek (0.5ml) but that was 2 years ago. Could that be the cause? How can I fix it
