Officials in Las Vegas are citing "operator error" in the death of a 24-year-old woman found inside a cryotherapy chamber at a business where she was the manager, the Las Vegas Review-Journal reported.

According to the state Occupation Safety and Heath Administration, Chelsea Ake-Salvacion was in the machine for more than 10 hours when her body was discovered inside the chamber at Rejuvenice.

"It's similar to microdermabrasion, but instead of crystals that exfoliate the skin, it's more of a suction machine," she said of using the chamber in a story published late last week. "After that, we apply a serum that protects the outer layer of the skin and moisturizes it. We like to do the cryofacial afterward because it helps seal everything in."

Ake-Salvacion said the treatment protects the skin by removing dead skin cells. The procedure gained attention nationally after pro basketball star LeBron James said he was employing it to deal with nagging injuries.

KLNV-TV reported that the chambers at Rejuvenice could reach temperatures of -240 degrees Farenheit.

"I do know that she was alone closing the shop up, and then did go into the machine and apparently did not turn off," said a friend of the deceased, Shae-Lynn Bee.

KLNV reported that normally, a technician is present when the machine is being used by a client, to ensure that the client's head is clear of the chamber to grant them access to oxygen.
