What type of algae is commonly referred to in treatments for its antibacterial properties?

The type of algae commonly referred to for its antibacterial properties is Phaeophyta, also known as brown algae. This group of algae contains various species that are rich in bioactive compounds, including polysaccharides and antioxidants, which are known to possess antibacterial effects. Specifically, compounds like fucoidan, found in brown algae, have been studied for their ability to inhibit the growth of certain bacteria and promote skin health.

Phaeophyta is often used in skincare formulations and esthetic treatments because of these beneficial properties, making it a valuable ingredient in products aimed at addressing skin infections, inflammation, and overall skin rejuvenation.

Other types of algae, like Cyanophyta (blue-green algae), Chlorophyta (green algae), and Rhodophyta (red algae), while they also have their own health benefits and applications in skincare, are less commonly associated specifically with antibacterial properties compared to brown algae.
