Types of nasolabial folds

[bob2]

Type 1: bulky NL folds due to fat deposits

Occurs mostly in young fat people.

Type 2: bulky NL folds due to fat deposits and aging

Occurs mostly in fat old people.

Type 3: thin NL folds due to aging

Occurs mostly in lean old people

And then there's the ones that are exclusively due to noticeable maxillary retrusion/downward growth

I have slight type 1 ones. I think it's a combination of genetics, retruded maxilla and poor fat storage, I'm fairly lean. They do get better in single digit bf% considerably, though, along with removal of water retention and facial bloat.
