Is co2 laser skin resurfacing safe for the genital and breast areas? I'm a 28-year-old model and was wondering whether co2 laser is safe for smoothing skin in the genital and breast areas (like skin tags)..

Safer. Methods for skin tags include excision, and electrodessication. They are cheaper, safer and easier.
CO2. Co2 laser can be used to remove skin tags, but it can be done quickly, cheaply and easily by simply snipping them off under a local anaesthetic. It shouldn't leave any scarring at all.
