I have just receive my first Fraxel treatment today. I am 22 years old, and I am an Asian male with darker skin. I have asked my doctor if she can use higher settings, but she recommended that I start at 30 mj and see how my skin reacts.Is it enough for my acne scars? My doctor said that my scars are not that bad,but I have heard that acne scars need to be treated at higher settings like 50 mj and up. Thank you for any response or feedback!
