If you have large breast it is probably because you sweat then it doesn't evaporate. If you put a barrier between the two layers it should help. An example would be a folded washcloth. The rash is usually a form of yeast. You can use Caladryl lotion to help clear it up. (it takes a few minutes to dry when you apply it.) I find powders seem to cause more irritation by clogging the pores.
U can also use the cream u use on babies for diaper rash. It works well and also when ur at home try not to wear a bra and if u can have ur doctor get u a scrip for nystop. Its a powder. I use it and it works very well when u have large breast's.
I TOO HAVE THIS PROBLEM. WHEN A RASH APPEARS, I APPLY "GOLD BOND POWDER" UNDER MY BREASTS. THEN I APPLY BURT BEE'S BABY POWER" . WHEN THE RASH IS GONE THEN ONLY APPLY THE "BURT BEE'S BABY POWER". "GOLD BOND" HEALS THE RASH AND "BURT BEE'S BABY POWDER KEEPS YOU VERY,VERY DRY ! "BURT BEE" IS THE BEST I'VE FOUND IN YEARS ! I'VE TRIED IT ALL AND WHAT I SUGGEST ID THE BEST! ALSO, WHEN NOT SHOWERING CLEANSE UNDER BREASTS WITH "BABY WIPES" FOR THEY ARE VERY GENTLE ! i hope this helps !
If you don't have any of these "health and beauty aid" products at hand and you have a box of corn starch, that works very well for chafed skin that has that raw, itchy feeling. Hope you feel better soon!
That is the downside of being a big busty girl. Nobody ever wants to talk about perspiration under the breast. But it happens. First you want to keep it clean under there. Wash thoroughly and dry. Use dusting powder to help absorb extra moisture and of course use antiperspirants to discourage sweating.
