I've searched for it, but couldn't find a clear answer, can AHA+ cause wrinkles? I've been starting to see some lines (even though I'm only 18), could this just be a coincidence or is AHA+ causing it? I'm using it twice a day..

AHA can actually help with fine lines and wrinkles since it exfoliates and helps bring new skin cells to the surface.

Still, AHA is pretty strong stuff, and using it twice a day seems like overkill. Why don't you try cutting back to only once a day, or even just two or three times a week? Some exfoliation is good, but there is such a thing as too much of a good thing.
