You may be a good candidate for a CO2 laser if you have skin problems, such as wrinkles, scars, sun damage, age spots, or uneven texture, that can be improved by removing the surface layer of skin. You should also be in good health, have realistic expectations, and be willing to follow aftercare after treatment. However, the CO2 laser may not be right for everyone. You should not undergo a CO2 laser if you have active skin infections, such as herpes or acne, dark skin tones, or skin that is prone to keloids, as these may increase your risk of complications, such as scarring, pigmentation changes, or infections. You should also tell your doctor if you have any medical conditions, take any medications, or have had any previous skin treatments. Your doctor will evaluate your skin type, medical history, and goals to determine if the CO2 laser is right for you.
