Collagen derived from fish scales could be used to heal wounds, according to a study conducted by researchers at the Nanyang Technological University (NTU) and National University of Singapore (NUS).

The scales, usually removed before cooking, contain collagen that can be chemically modified to be water-soluble and used for various biomedical applications, NTU said in a press release.

The modified collagen can also incorporate drugs to produce wound dressings with a higher healing potential, according to the findings from the team comprising assistant professor Cleo Choong and associate professor Andrew Tan from NTU, and associate professor Veronique Angeli from NUS.

Warning: HSA warns against Wonderglow, Tati skincare sets containing mercury

The Health Sciences Authority (HSA) warned consumers not to buy or use two cosmetic sets after beauty products in them were found to contain mercury and other undeclared, prohibited ingredients.

The authority found that some Wonderglow products contain an amount of mercury that exceeds permissible limits by 7,000 times.

HSA said in its news release that the products from the Tati Skin Care 5-in-1 cosmetic set contained mercury exceeding permissible limits by 50,000 times, as well as hydroquinone and tretinoin.

Long-term exposure to cosmetic products with high levels of mercury can cause serious health consequences, including damage to the kidneys, and digestive and nervous systems.

A consumer in her 40s was diagnosed with impaired glucose tolerance - which may increase one's risk of diabetes and heart disease - after taking the product for more than a month for her knee pain, HSA said.

While the product was labelled to contain herbal ingredients for the relief of joint pain and migraine, HSA tests later found it to contain dexamethasone, a steroid that should only be used under medical supervision.
