Cambodians are using a common condom lube to clear up their acne. They claim that very few other drugs work, but smearing the lube around on their face does the trick. I doubt it has much to do with the lube, but more with the Nonoxynol-9 that most condoms use as a spermicide -- if it's a gentle microbicide, it may be doing the job to kill off infections in a person's pores. Or their acne may be so embarrassed by having a condom wiped over them that they're hiding.
