I used this for a couple of weeks, when it came with a 14-day D.D.G daily peel regime. I have oily, acne prone skin, and found the texture to be kind of sticky in the aftermath. Luckily, it did not break me out, but I did not notice much of a difference in my skin's firmness or elasticity. In all fairness, I did only use it for about 3.5 weeks (until it ran out), but if something will work for my skin, I typically see a result within two weeks. This may be something to consider for those with more aged skin, to see a difference in firmness and elasticity.
