The women who created Proactiv skin care have introduced a new line for older users: You know, those who would probably not be influenced by an endorsement from Jessica Simpson or P. Diddy. Rodan + Fields instead focuses on anti-aging, like the Reverse kit designed to fade brown spots and uneven pigment, diminish fine lines and wrinkles and improve tone and texture. The kit ($135 at Nordstrom at Chandler and Scottsdale) contains an exfoliating cleanser, skin-lightening toner and lotion and SPF 15 sunscreen.Are you willing to put your skin in Reverse? I need someone to take the products on a test drive; shoot me a message so I can find the right reader. I’ll report the results in a future posting. In the meantime, you can catch company co-founder Katie Rodan explaining more about all the Rodan Fields products (and hawking them) on QVC at 2 p.m April 26.
