Dear Dr Baumann and anyone else!

I have re-read the Skin types book (aka the Bible) and have decided that I may be DSPW AND OSPW! Firstly, is this possible and secondly how do i treat myself withour going broke (I'm a student).

My cheeks are definately DSPW and i related to most of what is written in the book. Def the excema subtype (on body and sometimes face).

However I have blackheads in/on my nose 100% of the time and get the occasional chin pimple. Does this mean my nose/chin is OSPW. I am half Italian so i also related "sun goddess" part of the OSPW, and paula's sunscreen does give me that white/purple hue.

My cheeks were red and itchy with paula's choice one step cleanser (im guessing the sodium laureth sulfate). But using a OSPW foundations seems to not wear off so much. Im using a BHA on chin and nose, would it be okay on my whole face?

Any advice on which type to treat myself as. I'm in Australia.
Thankyou.
Lauren.
