McQueen, played by Gemma Merna, decides to use the machine in an attempt to look her best in her quest to become the face of new gym Attwell's.
The plan backfires when the machine explodes, reports the Daily Star.
Hollyoaks viewers will have to wait until a future episode to see if she survives, or the extent of her injuries.
Soap bosses are reported to have wished to give the air-head character a more serious and emotional storyline.
A source from the show said: "Carmel's life is on the line because she is desperate to get a tan."
The episodes will air on Channel 4 later this summer.
