How do women remove all their body hair without scarring, color changes or stubble? Kim kardashian has mediterranean ethnicity, but looks very smooth.

Technology.... Laser hair removal/reduction works great. The newer lasers can target all skin types colors... But is most successful on that mediterranean skin...Paler skin with dark hair. Seek out an aesthetic laser company and go in for an evaluation of your skin:hair type! good luck! :).
Air Brushing? Hair removal products abound; and there are newer [depilatory] agents for hair removal including laser treatments that have been proven effective. Not to take anything away from ms. Kardashian(as she is very attractive); but if you're looking at photos in magazines; they most likely have been 'touched up' to some degree.
