I use to have very red awful skin under my chin and lots of pimples. I had issues over it...still get the occasional pimples before AF but no redness. What helped to clear the redness was clinque products. Bit pricey...but i buy the wash in the pump and the toner (and nutrogena oil free mosituriser) and use them once a day and it genrally lasts about 5 months...so i dunno maybe have them do a skin test on u at ur local myer or David jones if ur curious... nothing else worked for me as they all irrated my skin.
The toner is impressive as u can see the dirt from ur face on the make up remover pad!!
