Canker sores by SLS
According to toothpaste expert Cody Levine, SLS is your biggest enemy in toothpaste. It causes skin irritation, he explains to Well + Good. His own products are therefore SLS-free. “This chemical is the most commonly used ingredient for making toothpaste foam and is also found in shampoo, soap and detergent. Although we all love the clean feeling due to a lot of foam, SLS is a proven irritant that can lead to dry skin and even mouth ulcers. ”We are not waiting for that …
Dermatologist Joshua Zeichner confirms that: “SLS is a known irritant that causes skin inflammation. It used to be often used in cleansers and toothpaste because it acts as a surfactant to remove dirt from the skin and gums. ”But, if the foam gets around the mouth, the skin can start irritating and inflamed. In addition, SLS can seriously dry out the skin, which, according to Zeicher, leads to a sharp rise in oil production. That in turn results in ulcers or acne, he tells Well + Good.
To keep our skin and mouth healthy, we will have to look for SLS-free toothpaste. Dentists, by the way, agree, says cosmetic dentist Dr. Jon Marashi at Well + Good: "As better products become available, I prefer toothpaste that is SLS-free." Do you want to purchase such a tube? Pay close attention to the label, because SLS can also be displayed as sodium lauryl sulfate or sodium lauryl sulfate.
