And making your own topical. I use glycerin to dissolve the crushed 25mg tablets, 2 at a time. But anything alcohol based, cream or otherwise will work as a solvent.

I've reached the 3 month mark, only 2 months of which I have been on spironolactone. But overall I'm pretty sure I can see some improvement. Not sure to what extent the spironolactone has helped, however. Always the problem with assessing the efficacy of these things - you'll find it difficult to get an objective judgement on how good spironolactone is because very few people opt for spironolactone alone.
