Four celebrities have reported to police and insisted on their innocence after endorsing substandard cosmetics and weight-loss products of Magic Skin Co.

Pitchanart “May” Sakhakorn, Napapa “Patt” Tantrakul, Nontaporn “Yae” Teerawatanasuk and Orapan “Aoffy Maxim” Dansiriwattanakun met deputy national police chief Wirachai Songmetta to insist on their innocence.

Ms Pitchanart said she and the other celebrities were in fact damaged parties because, like most people, they had no way of thoroughly checking the legitimacy of a product.

She said she did not know the owners of the company personally and had received product endorsement assignments through her manager.

She said she was ready to cooperate with police and the Food and Drug Administration in the propagation of proper product knowledge in the future.

Ms Napapa and Ms Orapan said they knew Wannapha Phuangson, owner of Magic Skin, and trusted her. They slightly checked her products and agreed to review them.

Ms Nontaporn said she and Kasit Worachington, one of eight suspects in the Magic Skin case, had been close friends about five years ago but she denied having any business relationship with him.

She said she used and checked the products that she reviewed on social media.

Pol Gen Wirachai said as the actresses had not been charged, they were treated as witnesses. Police would consult with behaviour specialists and would determine if any of them violated laws when they endorsed Magic Skin products.

Police would later decide whether to press charges against them, he said.

He also said that 55 other stars would be summonsed for questioning within 45 days.

On Thursday Pol Gen Wirachai said the stars who were hired for six-digit amounts for product endorsements, might have breached the cosmetics act since they used misleading words to promote the products. They might have also violated the food act when they falsely described the properties of food supplements and illegitimately advertised them.

The offences carry penalties of up to a year in prison and/or fines up to 100,000 baht.

They could also face computer crime charges for putting fake information into computer systems, liable to a jail term of up to five years and/or a fine of 100,000 baht, the deputy national police chief said.

On Sunday police raided a factory in Pathum Thani’s Klong Luang district following the arrests on the previous day of eight suspects who sold Magic Skin Co products with the trademarks Apple Slim, Slim Milk, Snow Milk, Fern, Magic Skin, Shinoshi, Treechada and Mezzo.

The products carried fake or inaccurate FDA certificates.

Pol Gen Wirachai said earlier that Slim Milk and Snow Milk products contained only powdered milk.
