Can tretinoin fix what tretinoin + the sun broke? (Photo)

doc prescribed tretinoin at .1%. I used it for 3months while working in the sun mon-fri. I think I used it too frequently without sunscreen. My pores got bigger, It became red, raw and very swollen around my nasolabial area which took weeks to heal. I quit tret in Aug, and havent used actives since. Can Tret fix the damage thats been done, if it is used correctly, with sunscreen and limited exposure to uv rays? *Is tretinoin more damaging on some skin types? Do you think its suitable for me?
