I understand where you're coming from. I've wanted to "fix" my cleft for YEARS. I am 26 years old and I can't even remember a time where I wasn't aware of it. We each have individual wants and desires and I'm right there with you! Whenever I have a picture taken I immediately photoshop it off my chin! I've also heard the, "...people pay to get those put IN." I think that whatever makes you happy is what really matters. Mine is also fairly deep... looks more like a crater than a crease. I've done so much internet research and come up empty handed. I am going to make an appointment for a consultation sometime this week so I'll repost when I hear what the doctor has to say. You don't owe anyone an explanation for your desire to improve your self-image, just go for it! Let me know if you find out any more information ;)
