Regarding open pores and scars, a thorough evaluation is required. It entirely depends on the type of pores u have. for eg: some may have a lot of oil production which may require soft peel with carbon lotion to decrease oil as well as pore size. some have acne marks which will be reduced with micro-needling and lasers. some may have excessive hair growth, which needs to be taken care of by laser hair reduction

This can be done with the help of CO2 Laser.
