The Department of Health (DH) today (November 30) appealed to the public not to buy or use a facial mask, namely Skin 18, which was found to contain an undeclared and controlled substance.
Acting upon a public complaint, the DH found that the above facial mask has been offered for sale at a retail shop in Mong Kok. Samples of the product were collected for analysis and test results from the Government Laboratory revealed that the samples contained fluocinolone acetonide, a Part 1 poison under the Pharmacy and Poisons Ordinance (Cap 138).
The DH's investigation is continuing.
Fluocinolone acetonide is a steroid substance. Products containing fluocinolone acetonide should only be sold at pharmacies under the supervision of registered pharmacists upon a doctor's prescription. Inappropriate or excessive application of steroids could cause skin problems and body-wide side effects like moon face, high blood pressure, high blood sugar, muscle atrophy, adrenal insufficiency and even osteoporosis.
According to the Ordinance, illegal sale and possession of Part 1 poisons are criminal offences. The maximum penalty for each offence is a fine of $100,000 and two years' imprisonment.
People who have purchased the above product should stop using it and consult healthcare professionals if they are in doubt or feeling unwell. They can submit the product to the DH's Drug Office at Room 1856, Wu Chung House, 213 Queen's Road East, Wan Chai, during office hours for disposal.
