Burns around and on the labia after 5th laser hair removal treatment. (photos)

I recommend following up with a Doctor for a formal evaluation. This may need topical steroids, antibiotics and possible Valtrex. See an expert. Best, Dr. Emer

Blisters and ulcers are possible from laser hair removal and applying the antibiotic cream is a reasonable place to start. It is likely that the sores are a herpes outbreak brought on by heat from the laser and will not respond to antibacterial therapy. This is not a rare occurrence and can be treated with Valtrex or acyclovir. I recommend calling the physician at the center where you were treated and having them assess you. If the treatment center does not have a doctor on site, I would recommend scheduling an exam with a physician if the lesions are still present.

This could be from higher laser settings, but it could also be a herpetic outbreak. Many times people have the herpes virus and don't realize it, until a trauma in the area exacerbates it and blisters form from that. It would be best to be seen by a dermatologist for an evaluation. "This answer has been solicited without seeing this patient and canno  be held as true medical advice, but only opinion. Seek in-person treatment with a trained medical professional for appropriate care."

The laser could have been too strong for you though after 4 other sessions your body should have declared itself.  I would get an exam to eliminate other less likely possibilities like genital herpes flare up.  Many can have herpes virus without knowing and then get a flare up with laser treatments.  Good luck.
