After extensive research (having attended the birth of three kids, and commenting on their complexions to a grandparent or two), I've realized you can have pimples anytime from birth to death, no matter how long a span of time that represents.

I've also come to the amazing realization that, just like almost everything else marketing departments touch, the aiming of certain medications at a certain age group that is known to have well-documented issues with such things as appearances and how others view them is really just a manifestation of pure evil, and a handful of lies to boot.
