The only good thing about it is that it
gets rid of some of your hair for some
time. It is not a 100% thing. That means
you should not expect it to get rid of all
of your hair for the rest of your life.
"Although laser hair removal doesn't
guarantee permanent hair removal, it does
extend the "hair-free" period, which can
vary from several months to several years.
With multiple treatments, long-term hair
removal is possible...
Studies show that for suitable candidates,
hair removal lasers can reduce hair counts
by 40 percent to 80 percent. Results vary
from person to person, however, and some
people respond better to treatment than
others.
Multiple treatments can prolong the
duration of hair loss, but hair regrowth
is possible. Also as you age, unwanted
hair growth inevitably continues, and you
may need repeat treatments in the
future....
Laser hair removal is effective only on
short, visible hair."

There are a lot of bad things about it,
although they are not life threatening.
"You may notice some redness and swelling
for the first few hours. Also, stinging
may occur for the first 24 to 48 hours.
Some people experience a slight crusting
of the skin. If crusting occurs, keep the
area moist with petroleum jelly
(Vaseline).
After treatment:
* Avoid exercise and exertion for the
first 24 hours. Perspiration from exertion
may increase irritation caused by the
laser.
* Avoid exposure to the sun for
several weeks after treatment. After this
period, make sure you apply sunscreen
whenever you're in the sun. Avoid tanning
booths — the ultraviolet light damages
the skin.
* Don't wax or pluck hairs between
treatments.
* Don't pick at or manipulate the skin
in treated areas.
Don't rub or scrub the treated area. You
may gently wash the area with soap and
water.
Side effects from laser hair removal
include, but are not limited to:
* Darkening of the skin
(hyperpigmentation). This is usually a
temporary condition, but in rare
instances, is long lasting or permanent.
* Lightening of the skin
(hypopigmentation). This is of special
concern with people who have darker skin.
Laser hair treatment is more successful on
fair skin, but darker skin can also be
treated.
* Blistering and scarring. These
rarely occur.
* Changes in the skin texture. These
rarely occur.
* Crusting or scabbing. If this
occurs, it's temporary.
* Hair changes. New hair growth may be
finer and lighter in color. In some cases,
new hair may grow in areas adjacent to the
treated areas. This can be successfully
treated with additional laser
treatments."

I would think that you are too young.
These things aren't free, and I don't
think most insurance would cover it, since
it is just a vanity issue. Also, doctors
are not usually willing to do unnecessary
procedures on young people. If you really
feel the need to remove your underarm
hair, you could try something like Nair.
