To treat acne, scientists from the University of Stirling (Scotland) have found a new treatment based on seaweed naturally rich in fatty acids.
Researchers reveal through this new scientific study that certain fatty acids present in algae have very valuable antibacterial properties effective in the treatment of acne.
Acne, like many other skin diseases, is linked to bacteria that normally live on the skin, Propionibacterium acnes (P. acnes) and Staphylococcus aureus (S. aureus). Today current treatments based on benzoyl peroxide, salicylic acid, and some antibiotics used to fight acne can cause side effects such as irritation or dryness of the skin, hence the need of find new remedies.
Previous research had already shown that fatty acids in marine algae (LCPUFAs) had anti-inflammatory and antimicrobial properties.
Researchers at the University of Stirling decided to study the effects of 6 PUFA-LC fatty acids on cultures of P. acnes and on 10 different strains of S. aureus.
Conclusive results to treat acne
The results of the study show that “added alone to bacterial cultures in the laboratory, these fatty acids are able to prevent the growth of P. acnes but are less effective against S. aureus. In contrast, LC-PUFAs are effective when used in addition to standard benzoyl peroxide acne treatment. ”
According to the researchers, “these initial results are very conclusive and warrant further evaluation of these agents present in algae not only to treat skin infections caused by P. acnes and S. aureus but also for alternative treatments for them. other forms of S. aureus infection, such as sepsis, septic arthritis or endocarditis. “
This study was presented in the specialized journal Marine Drugs.
