Monistat anti-chafing gel.
No kidding, really.
I am VERY porcelain to the nth degree as well as have *extremely* sensitive skin (I cannot handle anything with fragrance on my face). I also have lupus (SLE). I LOVE the Monistat anti-chafing gel-- and a 3 pack on Amazon with prime shipping and autoship is $15!
Hope this helps!
Warmly,
