Since ancient times, people have been taking therapeutic baths to increase both physical and mental well-being. Nowadays mud, mineral and peat baths and all kinds of natural packs and masks are offered in spas and wellness centers around the world.
The active substances in mud appear to consist of humic substances, which has given rise to an interest in the use of humic and fulvic acid in dermatology and cosmetics. Research shows that humic substances applied to the skin pass through the skin barrier, resulting in a pharmacological effect (Beer, et al., 2003). Because these substances have an anti-inflammatory effect, they are effective in the treatment of inflammatory skin diseases (Wollina and Abdel-Naser, 2004). In addition, it has a protective effect against UV radiation.
