Retonol Percentage

Hi. I am 33 years with acne prone skin and some visible smile lines. I am currently using Afirm 1x (retinol 0.25 for sensitive skin), with M2 20%( a combo of mailic and mandelic acid) on alternate nights. Also, I am using Cellex C (viitaminC serum) for sensitive skin( am). I was thinking of stepping up the level to Afirm 2X (higher retinol percentage) with M2 on alternate nights with Cellex C 10% (in the mornings). Would this regime be good for my skin? Also, does the TNS recovery complex really help in eliminating smile lines?
Lastly; since I am thinking of stepping up my retinol and Vitamin C % after 6 months use of all products; I need to understand if higher percentage of retinol implies more collagen production. Thanks for your time.
