I have too much redness in the area where my scars where treated with CO2 (laser machine company: G3 laser) every scar which was treated look more prevalent due to redness. I also feel that my scars have increased after the laser, is it possible or just my wrong perception ? Also what should i do to remove redness (please mention specific ingredient name for redness if possible) Can i use salicylic acid as it has been 20 days since i had my laser treatment done ?
