When SLS comes in contact with skin (especially your hands), it will remove more than surface grime. This is because the skin’s precious horny layer is mostly composed of a mixture of proteins and fats. This fatty-protein glue cements the skin cells together. After every hand wash with soap, some of these natural skin fats are removed. Repeat this five to 10 times each day and you can see what happens to your skin.
Hand eczema, therefore, becomes an occupational hazard for people like nurses, hairdressers and housewives.
