Nasolabial folds - do they need to be fixed now or should I wait? Would Retin-A work on them? I'm 32. (Photos)

I've noticed my NLF about 10 years ago, with time they became more pronounced. I also have them BELOW the corner of the mouth - is that the same type of wrinkle? I'm thinking of a Retin-A treatment perhaps it would smooth them out a bit, could that work? Also, would a HA filler work well on them? I only want a filler that can be dissolved. What would you recommend in my case? And is the reason I have NLFs so pronounced? Is it my bone structure or my relatively chunky cheeks?
