hi, i have a problem with ingrown hairs on my moustache and chin area. i know this is a great topical to prevent ingrown hairs because this is the same ingredient that the tendskin uses. but im thinking this is going to be more effective when i leave it on overnight. so im wondering if i can put a thin layer of aspirin only on my shaved areas where it is prone to ingrown hairs and leave it on overnight? because ingrown hairs are driving me crazy and it looks like an acne!

anyone tried this already?
your replies would be greatly appreciated! thanks!
