cream ## , I was told Eterna 27 was the bSam cream available. This was in Modeling School in San Francisco, back in the 70's. At the time I had oily skin, and didn't use it. Now I use Tazorac, a strond retinoid prescription cream, which leaves my skin dry and peeling at times. I bought some E-27, because it's no longer going to be discontinued, and I love the way my skin drinks up the moisture. What exactly is so good about this cream? Is it the active ingredient, Progenten? If so, what is in it...???
