=I did my research and found that the mud in Boryeong have minerals like Germanium and Bentonite which are supposed to be good for the skin. These studies were conducted by Korean research institutions like the Korean Institute of Standards and Science and the Korean Research Institute of Chemical Technology.
Here’s an interesting article I found. Read on:
Mud treatment options have proved to be vastly popular with spa goers around the world. Despite the popularity of the treatments, questions and confusion over the use and benefits of the “mud” continue to surface.
An issue that is commonly confused is the actual use of “mud” in salons and spas. Products and treatments are often labeled as “mud” in order to simplify the product for consumers as well as for lack of a different term. It is this term that may have lead people to question whether their mud bath is not really filled with an expensive version of mud from their backyard, and could in fact be a dirty and unsanitary practice. Backyard mud contains high levels of toxins, such as lead and bacteria which can in fact have detrimental effects on the skin. Fortunately, most spas and salons utilize mud consisting of seaweed, volcanic ash, clay as well as other mineral rich substances which are mixed with natural or spring water. The Dead Sea mud is still recognized as one of the most beneficial forms of mud available, due to its high concentration in salt and minerals.
But is the mud bath still sanitary when other spa goers have bathed in the same bath as well? Well the answer is yes. You will be happy to know that the mud bath is sterilized after each use. This is usually done by adding boiling water to the mud for 15 mins and then draining it away after each mud bath is taken. The mud is also often raked and new mud is added after each visit. This ensures that the mud is sterile and fresh, guaranteeing a healthy and positive experience.
Besides the relaxation benefits of mud treatments, the mud also has a number of benefits on both the skin and body. The mud aids with blood circulation, skin detoxification and purification, removal of blackheads and blemishes, has anti-ageing properties as well as other added benefits. Depending on the type of mud used and its ingredients, it can be used for both cosmetic and healing purposes. Due to its water solubility, mud allows the skin to absorb nutrients from it or other products applied along with it.
Home based mud treatments are also now widely available, however they do not compare to the therapeutic experience received at a spa or skin clinic. The natural ingredients in mud products stain clothing and fabric and it is difficult to cover your entire body with mud. For this reason alone, a visit to your local spa may be the best way to experience a healthy and relaxing mud treatment.
