"i have been taking aldactone for adult hormonal acne for almost 2 years and i cannot even put into words the huge difference it has made. in my early 20&#039;s, i began getting horrible cystic acne all over my chin and entire jaw line area. i had used every product available including proactive, expensive designer dept store lines, retin-a, birth controls etc...nothing helped! i&#039;d have 5-15 painful nodules at once, each lasting 2-3 weeks and most scaring. my self-esteem was ruined, i was ashamed. finally, at age 28, i went to a dermatologist and started on aldactone 100mg/day. i saw noticeable improvement within a week and was totally clear in one month! increased to 150mg/day after 3 months and have had flawless skin since. truly a lifesaver medicine."
