Recoverable cosmeceutical ingredients from marine discards/by-products

Cosmetic products with marine-derived ingredients instead of synthetic ingredients are indeed particularly attractive to consumers, and that is why the demand for these products has increased in the last decade. However, natural resources, including marine resources, are limited and should not be overexploited because their regeneration involves the passage of many years. One of the solutions for natural resource depletion is to recover their discards and by-products. Therefore, this issue has led to the use of marine discards and by-products produced in the fishing industry as a sustainable source for extracting high-value ingredients that are used in the cosmetic industry. These ingredients such as collagen, chitin, natural calcium phosphates, astaxanthin, and phycobiliproteins could be utilized as antioxidants, anti-photoaging, anti-wrinkle, anti-acne, and anti-inflammation in cosmetic formulations. As a result, in this study, according to the importance of the subject, the potential of marine discards and by-products to extract effective cosmeceuticals was discussed.
