Hello! Recently I've started to experiment with Korean skin care brands so I bought the Cosrx low pH good morning gel cleanser because I heard a lot of great reviews that it's very gentle and suitable even for people with dry sensitive skin. I started using it but I noticed that after washing and even after moisturising my skin was red dry and itchy even stinging at some places. I thought that maybe it's because it's a deep cleanser and my skin is still not used to it so I continued using it but it kept getting worse and even more painful. Now I have pimple like spots and bigger red spots and I have to use calming creams and moisturiser to help with the pain and itching. I researched for reasons and I found out that with that product this happens to people who have an allergy to tea tree oil so now I've been avoiding products with that ingredient. Today I was watching reviews of the Some by mi AHA BHA PHA 30 day miracle serum and I was sold but on the last review I watched it was mentioned that it contains tea tree leaf water. I started researching again and I read that tea tree lead water is not as strong as the essential oil but I still don't know if I can use it. Can someone with more knowledge on these products give me an advice?
