Is this reaction to laser hair removal normal? (Photo)

You develop a concernWhenever a patient develops a concern immediately after undergoing any type of aesthetic treatments I strongly recommend consulting with the physician who performed or is supervising the treatment.  That isthe best first place to start.

Itchy red bumps is related to inflammation of the hair follicle and means that there was probably adequate heat to kill the germinal cells. Applying topical hydrocortisone will help subdue this reaction and make you feel better. 

As always, you should consult immediately with the treating physician, who can evaluate you in person.  The primary worry with laser hair removal is a thermal injury to the skin such as raw spots or blisters.  Your reaction is discrete and appears to in most part surround the actual follicles which suggests just a swelling reaction to the laser's destruction of the follicle.   Your hair appears to be very course.  With course dark hair there is often a significant disruption to the hair follicle, causing temporary swelling.   If a patient has very course hair and has not had previous hair removal treatments, sometimes it's necessary to reduce the fluence (dose) and or the pulse width of laser emission, at least until the hair begins to thin and the remaining hair grows back with a narrower diameter shaft (and hence less reactive to the laser).  Your doctor can recommend some topical and/or oral treatments to hasten the resolution of these temporary reactions as he/she and you decide.
