Thanks to suggestions on here, I took the plunge and bought the Roche Posay Effaclar Duo - the cream in the long tube.
I am genuinely stunned by the results. I usually get two hormonal break-outs per month - one around ovulation, one before my period. After a week on Effaclar, my ovulation breakout consisted of ONE spot, which faded and passed quickly.
Now, the question is - do I get the Effaclar face wash and other products too, or is the cream enough? I'm using Nutrogena face wash at the moment, and Clarins moisturiser as well as the Effaclar (not sure if this is recommended or not, but I find it too drying on its own). I don't want to dry my face out too much by adding more Eff. into the mix, but I am so pleased with the results so far. I want it to continue!
