Clean start dermalogica breaking me out ?

soo i got the clean start dermalogica kit during xmas break and ive been using it for a month now and at first it worked great then a week or two later underneath my chin started to itchh sooo much and burned and i didnt know why and i didnt think it would be the kit and now it doesnt itch as much but still just a bit, now i realize i am still randomly breaking and idk if its the kit and ive just tried ponds moizturizer and maybe that could be it, since its too think, as well as i do wear face makeup to cover it up but ive been using that for years and it doesnt break me out, also i have very dry and very sensitive skin and i have a lot of mini breakouts and scars. so i was wondering if it was the clean start kit ? and i only use the wash off cleanser that has 5% salislyic acid and i use the toner and the bedtime for breakouts.
