"i take the .01% and i&#039;m so glad i can. i still have to take spironolactone for a continuing problem with cystic acne but the combination is ideal. i also love what it&#039;s done for a few little brown spots. i&#039;ve been on it maybe 3 years and i just didn&#039;t think it was going to sand down some of my little raised acne scar/specks but i can finally feel the results now. growing up i felt like a monster with my acne and, eventually, i was fortunate enough to be prescribed accutane, not once, but twice (thank god)! i had the worst and the lowest self esteem imaginable. yeah accutane (big time yeah)!! yeah retin a / tretinoin! it will never erase my scars, i need a real sanding down for that, but it has raised my self esteem."
