thank you for sharing your experience! i'm happy to hear something has worked for you!
saw palmetto is just the "natural" form of Spironolactone. I have tried Spiro and it completely dried up my skin. in addition, it made my breathing irregular and my heartbeat to go up. though most people have had success with megadoses of saw palmetto it looks like you have found the lower dose to be effective. good thing because any more and you'd probably have to monitor your potassium levels.
anyhow, what cleanser or topical treatments are you using?
