Active Components and Skin Care Mechanism of Sea Grape (Caulerpa lentillifera) Extract

Abstract

This study successfully obtained sea grape extract through mechanical extraction methods, which is rich in active components. These primary active ingredients include high concentrations of crude polysaccharides, total phenolics, and flavonoids. Using two zebrafish models, we observed significant skin moisturizing and repair effects of this extract. Further experiments demonstrated its remarkable anti-aging and skin tightening effects through the DPPH method and elastase inhibition assay. Additionally, the extract showed significant anti-inflammatory effects in a model built on 3 dpf (days post fertilization) Tg (corola: EGFP) transgenic zebrafish. The extract’s safety and reliability were confirmed through a final dermal application test on rabbits. Furthermore, we also analyzed the possible mechanism of Caulerpa lentillifera extract skin care. Overall, our research indicates that sea grapes hold tremendous potential as a novel natural ingredient for skincare. It is foreseeable that sea grapes will become an indispensable component in the future medical skincare market.
