How Long Should I Stay out of the Sun After Laser Hair Removal?

You don't want to get tanned or have sun exposure for a good six months minimum after laser hair removal if you are prone to getting hyperpigmentation as a response to trauma (acne, burns, scratches, etc.). Also, if you have a tan, then you can't be treated with laser hair removal until the tan goes away otherwise there may be an increased risk of complications.

Patients should avoid the sun 4 weeks prior and 4 weeks after laser hair removal.  The skin may continue to be sensitive so patients should use sun block as necessary.

The armpit is generally not exposed to sun light unless the arms are extended. Sun exposure following arm pit laser hair removal is not an issue.  In areas that are exposed, sun avoidance and/or sun block should be used for approximately 2 weeks (longer if you are a darker skin type that is prone to pigmentation).  Laser hair removal should be postponed following acute sun exposure for 2 weeks.  As a further precaution the fluency can be decreased (the parameters can be changed for a darker skin type.)
