Acne for Adults? Why?

So I was someone who was blessed to not have acne as a teenager and I truly am grateful for that. Not so grateful that I have now come into the ripe age of 30 and have found that my skin is the worst it has ever been. Literally I sit at the beauty counter and look at acne and anti-aging products, that is wrong. I have actually found that a few companies market products for both, such as Murad with there acne fighting, anti aging product line. I am in the 4th week of this line which includes a very nice cleanser and fabulous toner, a "treatment" that I'm still unsure of and a moisturizer that seems decent. Not to be forgotten is the 2-3 times per week mask. I have to say that my favorite esthetician did tell me that I have to actually wait at least 6 weeks before I swear off anything. I love the products however I am not sure if they are doing anything for my skin. It hasn't gotten worse but I haven't seen it get better either, I'm hanging in there at least until my product is gone and then I will move onto the next.
