Should I use more gel for acne scars after the Fractional CO2 Laser (10600nm)? (Photo)

Dear Doctors, I had Co2 laser done last week ( February 2). After this laser treatment, i feel that my acne scars aren't improved better. It still existe deep scars on my cheeks. Should i use more gels for acne scar ( Mederma, Hiruscar post acne, Ultra Dermatix,...) to get the best treatment? How long will I use theses medecines? When ? ( after 5days from laser treatment). Thank you very much !
