Is The distribution by cosmetics companies have a problem with working freelance for another if not in direct competition, but both have some of the same products in general, such as lipstick, mascara, etc. is generally employed only if you work for our cosmetic company can not work for another? Thank you very much and please respond if you have worked for cosmetics Compan (s) before. Thanks

When I was working I worked for several different companies at once. So there is no a scheduling conflict, which was in sales volume and product knowledge. If you can / know quickly learn the product and is sold in high demand. I've never had a problem with working with several companies simultaneously. In fact, I helped negotiate more hourly rates.
