Magic Skin Co Ltd has been accused of unauthorised use of Food and Drug Administration (FDA) marks and producing substandard products.
Police investigated the allegations after several consumers lodged a complaint.
On Saturday, police arrested eight suspects for their alleged roles in the company and froze the firm’s assets. The firm’s bank accounts reportedly had a cash flow of over Bt100 million.
Tourist Police Division 3 chief Pol Maj General Angkoon Klaikleung said on Sunday that the suspects said they hired a factory in Pathum Thani for product manufacturing.
As a result, the search was conducted at the plant. Chemicals at the site were collected for examination.
