Anyone out there tracking the condition of their skin and appearance? Not so much medical conditions (i.e. eczema, psoriasis…) but just general things like dryness, tight sensation, oiliness, breakouts…
Cosmetic literature talks about all sorts of measurement devices (i.e. TEWL(irriation), Sebumeter(oil), corneometer (hydration), pH…) so was wondering if anyone has experience with that type of tracking?
