Algae Extract is renowned for its incorporation of essential micronutrients, including iron, manganese, zinc, magnesium, and copper, which, although present in trace amounts within the human body, are crucial for the metabolic processes of the skin. These micronutrients contribute significantly to maintaining skin health by supporting various cellular functions and facilitating effective metabolic activity.

This work analyzed the trends in the use of marine ingredients in a set of anti-aging formulations sold on the Portuguese market. Algae extracts are undoubtedly the most commonly used marine ingredient in these anti-aging formulations, probably due to their biodiversity, ease of cultivation and growth regulation.
While in 2011 only 6% of the 190 anti-aging cosmetics were of marine origin, a clear increase was observed in 2018, with 33% of the 103 anti-aging products newly studied using these ingredients.
Anti-aging effects of green algae extracts on the skin
Taking green algae extracts as an example, the bioactive ingredients and their effects that exert anti-aging effects include:
· Ulvan: This is a water-soluble sulfated polysaccharide extracted from the cell wall of algae with moisturizing, protective, anti-tumor and antioxidant properties.
· Other bioactive ingredients include chlorophylls (a, b, c, d), lipopeptides, tripeptides (arginine, glycine, aspartic acid), carotenoids (lutein, beta-carotene, fucoxanthin, astaxanthin) and even fatty acids, which have a wide range of properties including antimicrobial, anti-inflammatory, antioxidant, coloring, deodorizing, stimulating tissue growth, chelating, gelling, moisturizing and protective properties.

Red, brown and green algae contain antioxidants and have anti-aging potential. The chemical composition, total phenolic and flavonoid content, antioxidant activity and toxicity of these algae extracts were studied in this work and formulated into serum preparations.
· Component Analysis
Padina Australis, Ulva Reticulata, Sargassum Oligocystum and Euchema Cottonii contain chemical components with antioxidant activity, hexadecanoic acid, methyl esters, fatty acids and phytol. These algae extracts all showed antioxidant activity.
· Formulation of Serum Preparation
Algae extract serum was prepared by dispersing carbomer in warm water at a speed of 150 rpm using a mechanical stirrer until a gel phase was formed. Sodium bicarbonate, nanosilver and 96% ethanol were mixed and then added to the gel phase. Euxyl and glycerol were added to the compound until homogeneous. The algae extract was diluted with 96% ethanol and then added to the serum matrix and stirred for 30 minutes before TEA was gradually added at a speed of 500~700 rpm.
· Evaluation Results
These algae extracts were shown to have low toxicity with LC50 above 1000 ppm. Based on the results of stability testing of each anti-aging serum formula, the formula containing E. cottoni extract showed a stable serum formulation.
