Skin crisis intervention, indeed - I have been using the Obagi NuDerm System since developing adult acne 5 years ago, but still suffered from deep cystic acne in the lower portion of my chin, and laugh line area of my face. I bought this product 3 months ago, combined with Retin-A and a Clay-Mask product (for men) my skin is FINALLY break out free. No more weeping cysts & cycles of break-out/healing.. I am now reordering it.
As for the men's clay mask product I read that cystic acne in adult women c/be caused by hormone fluctuations particularly in progesterone & testosterone later in life. No clue if that is true, but it definitely worked.
