Hi Moley, I had high hopes for FemSeven conti when they were re-released, but I had terrible skin reaction to them too, so had to stop using them.
I have also tried Evorel conti which is changed twice a week and they didn't irritate my skin at all, neither did Estradot 50 when I used those. I use the gel now all the time.
Hope you find your best solution, a lot of us still struggle!!
