The development of an innovative sunscreen based on Cucumaria frondosa extracts: a sustainable approach without traditional chemical filters.

The project aims to develop an innovative and eco-friendly sunscreen, free from traditional chemical filters, by leveraging the unique properties of marine bioresources, particularly those of the northern sea cucumber (Cucumaria frondosa). This marine species is rich in bioactive compounds such as mycosporine-like amino acids (MAAs), sulfated polysaccharides, and collagen, which exhibit exceptional UV protection capabilities, as well as antioxidant and anti-inflammatory properties.

The primary goal of the project is to create a new generation of dermocosmetic sunscreens that meet the growing consumer demand for safer and more environmentally friendly solutions. By utilizing natural extracts from Cucumaria frondosa, we aim to offer an effective alternative to UV chemical filters, which are often associated with negative impacts on human health and marine ecosystems.

The project will be carried out in several phases, including the extraction, purification, and characterization of the bioactive compounds present in Cucumaria frondosa. These compounds will then be incorporated into pharmaceutical formulations that will be tested for stability, photoprotective efficacy, and safety. Cytotoxicity assays, as well as biological tests, will be conducted to ensure that the formulations meet the highest safety standards for skin health.

In addition to health and environmental benefits, this project will also contribute to the valorization of marine resources from Quebec, particularly those derived from local fisheries. The sea cucumber is an abundant species in the northern Atlantic waters, and its use in high-value products such as cosmetics presents new economic development opportunities for the Quebec marine biotechnology sector.

Collaboration between academic and industrial partners, such as DCP Dermoscience, is at the heart of this project. Together, we aim to launch a product that is not only innovative but also sustainable and biodiversity-friendly, while positioning Quebec as a global leader in marine biotechnology and sustainable cosmetics. This project also has significant export potential, as it meets the growing demands of international markets for natural and eco-responsible products.

In summary, this project is part of a vision of sustainable innovation and natural resource valorization, with the ambition to develop an effective and environmentally respectful sunscreen solution, while supporting the growth of Quebec's bioeconomy.
