Well, firstly, you must realize that no single product will work for everyone. This goes for OTC products as well as Acne Free in 3 Days. Fortunately for you, Acne Free in 3 Days by Chris Gibson has an astounding success rate of 98%, which is actually higher than any OTC product, including Accutane.
For the 2% of people who fail with the program, there is a full money-back guarantee offered. So there really isn't much risk involved with this product.
To sum up what the program actually is... it is a 3-day detoxifying program. The diet concentrates on foods which rid the body of nasty toxins, particularly in the colon. These toxins cause inflammation and thus, acne. The diet also helps the liver control the amount of hormones produced which allow for oily skin.
Since I've used the Acne Free in 3 Days program two time and seen amazing results the second time. I failed the first time, but that's somewhat expected since my chronic systic acne has been with me for years. On second thought I gave the program another go and I used it for 5 days. The second time around I used it for a longer time and endured past the 3 day level to ensure results and lo-an-behold, just 5 days later I was seeing success. I recommend this program to any chronic acne sufferer.
In my opinion Acne Free in 3 Days by Chris Gibson is an incredibly effective acne program. It's 100% natural and doesn't require any goo or creams. It's success rate is higher than any OTC product and it's delivered with a 60 day money back guarantee, it's safe to try risk free!
