Hi guys, just a quick question for anyone with experience of Epiduo or retinoids in general. I know the instructions say to only use a thin layer once a day but i have some stubborn closed comedones in a certain areathat wont go away so i am thinking of using it to spot treat these in the morning as well as using the Epiduo all over at night. Is this a really bad thing to do with a formula that contains a retinoid? Will it harm my skin?

Also while I'm posting about Epiduo anyway, what kind of time frame did you guys begin to see positive results in? i have seen some improvement but i still have some closed comedones that haven't come to a head yet, I've been using the Epiduo for about 9 weeks

Thanks in advance!
