hi...From what you have mentioned, it looks like an allergic reaction
to lip balms/ moisturizers/ even toothpastes is possible..my advise on the red flaky skin would be to stop changing products frequently..
You should do well with a week of mild topical steroid
and thereafter application of a medicated moisturizer( odorless and colorless)Please try this and let me know how you are doing .
As for the acne
, tell me what kind of eruptions you get and what kind of skin you have?
