The hydrobiome is defined as the natural microbial community present in water. Thermal spring water contains macro and microelements, as well as trace elements that have proven their effectiveness in treating several skin conditions such as atopicdermatitis and acne. Recent research has linked the hydrobiome of these waters with a balance of the skin’s microbiome.
A summary of what we know:
Microbial diversity has been investigated in several waters and is shown to be impacted by factors such as environment and mineral composition (Mourelle, Gómez and Legido, 2023)
Studies have shown the dominant bacterial phyla in several hots springs to be Actinobacteria, Firmicutes and Chloroflexi (Mourelle, Gómez and Legido, 2023)
A recent study compared the effects of Lakitelek thermal water and tap water on the skin’s microbiome in healthy volunteers, showing that the number of inflammatory agent Pseudomonas decreased and the Deinococcus genus increased, which is known to play an important role in inhibiting Staphylococcus aureus infection (Tamás et al., 2023)
Additionally, hypersaline environments such as water from the Dead Sea have been recognised as treatment for various skin diseases (Dai et al., 2023)
Industry impact & potential:
Several companies have conducted research on hydrobiome-derived ingredients such as extracts and lysates. There is huge potential for these ingredients to be used in cosmetics as bioactive ingredients, however, there is a lack of research on how the hydrobiome of thermal waters can play a role in having therapeutic effects on the skin. More in vivo studies are needed to identify the interactions between the hydrobiome and the skin microbiome.
Our solution:
If you are interested in formulating with thermal water or hydrobiome-derived ingredients, we offer formulation support and in vivo microbiome testing to demonstrate the effects on the skin microbiome and substantiate microbiome-related claims.
