Hi,
So I've been using the first one for about 5 or 6 years. I'm 32 and I really like it. The serum, that is, not my age 
I just went to repurchase the Advanced one, but I've accidentally picked up the Advanced Intense- the next one on. Oops.
I have it in my head, this is more for 40 plus. I can't really be arsed to take it back, but then I don't like using something that my skin doesn't really "need" yet iyswim. Kind of like I would have nowhere to go for the future when I get more wrinkly 
What do you think?
