Crazy rash on legs after laser hair removal

I had laser hair removal on my bikini area with no problems.  I've had two treatments on my legs.  The second one was today and for the second time I have a horrible, crazy itchy rash all over my legs.  There are literally hundreds of red dots all over them.  Cortizone cream only helps a little bit.  Last time the rash lasted for a full week and I'm wondering if there is anything I can do to

a) help make the rash less itchy
b) stop it from happening for the next three treatments

Also any thoughts as to why this is happening on my legs and it didn't on my bikini line?

Thank you!

Hello,
It looks like you are having folliculitis or allergic reaction after laser hair removal.Side effects of laser hair removal can include blistering, discoloration after treatment, swelling, redness, and scarring.
Do not use any cosmetic products at the sites. You can apply some calamine lotion at the rash as it will help in soothing the skin. You can take some OTC oral antihistamine medications like Benadryl or Claritin and see if it helps.

For mild-moderate symptoms a weak steroid may be used (e.g. hydrocortisone as dermacort), whilst more severe cases require a higher-potency steroid (e.g. clobetasol propionate, fluocinonide). Also use good quality moisturizers to prevent moisture loss from the skin and a sunscreen with spf 30 before going out in the sun.

If still the symptoms do not improve then pls get a clinical examination done by a dermatologist.
Hope it helps.Take care and pls do keep me posted on how you are doing or if you have any additional doubts.Kind regards
