I'm a 20 years old guy with acne. I drank 3 cups of green tea per day, before every meal, mixed with a bit of sugar, for 1 week. I also applied once or twice a day the tea bag on my face.<br/>It did quite literally nothing for my acne. My advice is to not waste your time on home remedies since as the site says, they're largely ineffective. I tried it for like 10 days, but it's probably enough to see if it works or not.
