I first used this product on the night of the first day I bought it, and in the morning, I could already see its effects. My face is clearer and some of my blemishes have disappreared. The more hectic scars are still there, but are greatly reduced. I think I'll continue using this product until I'm dead (or completely flat broke). Only thing I'm sad about is, it doesn't last as long as I thought it would. I don't think I'm using too much, but I'm already on my second bottle in less than 3 months. Would be nice to have bigger bottles as an option, even if they would be more expensive than the smaller ones.
