Core Viewpoint - The controversy surrounding the collagen product "Human-Like Recombinant Collagen Essence" from Giant Bio is primarily focused on the alleged discrepancy between the claimed and actual content of recombinant collagen, with accusations of misleading advertising and lack of industry standards for testing [1][4][5]. Group 1: Allegations and Responses - A blogger claimed that the actual recombinant collagen content in the product is only 0.0177%, significantly lower than advertised [1][4]. - Giant Bio responded by stating that their internal tests show collagen content above 0.1%, disputing the blogger's claims and questioning the validity of the testing methods used [1][5][6]. - The blogger criticized Giant Bio for not addressing two key scientific questions in their response and emphasized the need for transparency and accountability [2]. Group 2: Testing Standards and Methodology - The lack of established industry and national standards for testing recombinant collagen in cosmetics has led to disputes over testing methods and ingredient definitions [3][6]. - The blogger used HPLC (High-Performance Liquid Chromatography) to detect amino acid content, finding only 0.0177%, which raises questions about the product's labeling [4][10]. - Industry experts noted that the testing methods used by both parties require proper validation to ensure reliability, and the methods referenced by Giant Bio may not be directly applicable to cosmetic regulations [6][7]. Group 3: Ingredient Definition and Labeling - The core issue also revolves around how recombinant collagen is defined and whether the product contains genuine collagen, as the absence of glycine in the test results raises doubts [8][11]. - The blogger argued that the product's labeling as "soluble collagen" may mislead consumers regarding its actual collagen content, similar to how other cosmetic ingredients can be misrepresented [7][11]. - Giant Bio claimed that their product meets labeling regulations, asserting that the soluble collagen content is above 0.1% and should be listed as a primary ingredient [6][9].
