Please recommend a good place. I think my friend made a mistake and got a dent on his face. I'm planning to try Rejuran as well. I use Rejuran once a month to make my skin glow. I want to try Ulthera, but I'm worried about my friend. If I do it wrong, I'll end up with serious dents in my cheeks. ㅠ They say it hurts a lot, so please recommend a good hospital.
