Cosmeceutical Potential of Grateloupia turuturu: Using Low-Cost Extraction Methodologies to Obtain Added-Value Extracts

The invasive macroalga Grateloupia turuturu is known to contain a diversity of bioactive compounds with different potentialities. Among them are relevant bioactivities for cosmetics. Considering this, this study aimed screen cosmeceutical potential, namely, antioxidant, UV absorbance, anti-enzymatic, antimicrobial, and anti-inflammatory activities, as well photoprotection potential. Extractions higher concentrations ethanol resulted in extracts antioxidant while the anti-enzymatic activity, high inhibition percentages were obtained elastase hyaluronidase almost all extracts. Regarding antimicrobial showed be active against E. coli, S. aureus, C. albicans. Extracts produced more effective coli lower other two microorganisms. Several each extract found safe fibroblasts, but no capacity was observed. However, one aqueous responsible reducing around 40% nitric oxide production on macrophages, showing its This work highlights G. turuturu’s potential field, contributing further development natural formulations skin protection.
