As it stands, the 25-year-old has currently been released on bail while The Thai Food and Drug Administration (FDA) investigate the products she was selling.
Nitthakarn's ad is featured in its entirety below:
"The produce advertised is registered, as a cosmetic body care in the form of whitening substances, so it must be checked whether the message is displayed as requested with or without the whole label and substances used," Dr. Somchai Preechaavejkit, Deputy Secretary General of the FDA, added.
"We believe that there is an advertising fault because claiming there is an instant switch in color of the bottom from dark to white is not allowed."
Nitthakarn has responded to this criticism claiming that the results she showed were genuine and that she was not trying to be provocative. She also claimed that her products complied with the country's trading standards.
"I have a child to support and no husband," the single mother said. "I am just trying to take care of myself and my daughter."
Nitthakarn's questionable ad comes just a week after it emerged that a growing number of Thai men were having their penises whitened.
