free sample of topical probiotic lotion

The website is http://www.probiotic-lab.com and they make probiotic products for acne. They send out free samples — I think the sample is of the lotion, although it looks like they have other skin care products also. It doesn’t really specify what the other products are, though, that I could see. I figure it’s worth a try, because probiotics help internally, so why not externally?
