Please recommend a procedure that is effective for improving nasolabial folds.

My mouth area is slightly protruding.

I'm not sure if it's because of that, but my nasolabial folds look unusually deep.

When I look in the mirror, it seems like my complexion is deepening day by day, and I can see shadows forming even without moving my facial muscles much.

What kind of procedure would be effective in this case?

More than anything else, I want it to look natural.

I would like my wrinkles to look a bit lighter without my face looking too swollen. Would Botox be the most effective treatment in this case as well?

I'm not really keen on Botox because I've heard it makes the face look unnatural and stiff. I'm wondering what other procedures would be more natural and effective.

I would like a procedure that is as natural as possible and has no side effects, even if it takes a little longer.
