During puberty, the levels of androgens in both boys and girls
starts to climb and begins to stimulate your oil glands to grow and
produce more sebum. If you develop acne, you probably don’t
have higher amounts of these androgens; it’s more likely that you
have a higher sensitivity to them. You can flip back to Chapter 3 to
see how this happens.
And how’s this for an entry in the “perfect timing” category: Just
when you guys begin to shave, up pop those bumps that get in the
way of your razor. Now you have the added problem of having to
shave over and around those papules and pustules. It’s like an obsta-
cle course! Turn to Chapter 19 where I give some shaving advice.
Thanking your family:
The heredity factor
That’s right. You may be able to thank your mom, dad, aunts,
uncles, and grandparents for the current state of your face. Check
in with your parents and their siblings to see whether they’ve had
acne too and how severe it was. If acne runs in your family (or
even hides — it may be lurking under shirts and blouses!), you’re
more likely to have it too. Feel free to drop them a thank-you note.
If both of your parents had acne, you’re even more likely to have it.
In fact, identical twins tend to share acne problems just like they
share looks. And they got their acne genes from their parents, who
inherited them from their parents, and so on, probably back to the
Stone Age.
Why is acne hereditary? Well, for the same reason anything is
inherited from your parents: for instance, the color of your skin,
eyes, and hair. Scientists are still trying to pinpoint the exact
genetic cause or causes of acne. We do know that you inherited
something from your parents that tells your body:
How much oil to produce
How big or small your oil glands are
How sensitive your oil glands are to androgens
How easily your pores get clogged
How quickly your skin cells replace themselves
How quickly your immune system reacts to the acne-producing
bacteria, P. acnes.
All these instructions are just swimming in your gene pool. And
sometimes, what finally emerges is often just a matter of luck! For
more on how these points meld together to actually form acne,
turn to Chapter 3.
If you were adopted, you inherited the acne tendency from your
biological family.
