Bad skin, boils and acne seem to go with most chemical engineered Pro's. Some workout cloths have been know to have stains on them, during and after workouts, from skin problems. And that's just the female BB'ers. Looking at the women close, up a lot look like 40 miles of bad road. All the chemical used can give off a very bad smell to some of them. Plenty of soap and hot water or not.
Under the lights or photo shoots, whole body makeup (including blended oils) is used heavily. Pic's are air brushed also.
