I bought folligen 2 and a half years ago and stored it in the fridge. Do you think it's gone to waste or, on the contrary, should I still be able to use it?
Because I read it was just totally ineffective and gave up using it, I thought I was just wasting my time. Now, as I arrived at this forum, I read it was effective... I read it was even more effective than zinc+b6+azelaic, which is what I was using instead of folligen.
OK so try your folligen and put your zinc+b6+azelaic into the fridge instead.
Seriously though after 2 and a half years just through it away and buy some more. I dont know if it will still be any good but its hardly expensive so get another bottle.
