Tretinoin and smile line

I have been using tretinoin 0.5 for the past 2 months. I have faced extreme peeling and now finally I have come to a point where I have found my window . So far I have very happy with it . Following are the benefits I saw with tret.

1: visible reduction in pore size
2: glowy skin.
3: tone getting better somewhat
4: over all healthy and soft skin
5: visible reduction in frown line

I am in my early 30s and I feel like my smile lines are getting visible . Can it be possible that tret is doing that . Help please
