Hi, I am 21 years old. When I was a teenager I suffered from acne. Due to this I started using harsh cleansers which got my skin super oily. Now I am left with super oily skin and enlarged pores on my nose and cheeks. I get blackheads often especially on my nose and lately also getting acne on my face. My nose is now left with these huge pores left by big blackheads and acne. Also have enlarged pores on cheeks. How do I treat these scars? Heard about CO2 laser and TCA cross. Please help. Thanks
