LINHART Tooth Whitener Gel is a perfect supplement to your everyday toothpaste. The enhancer gel does not rely on abrasives, but uses hydrogen peroxide to achieve the desired whitening effect. Just place a drop on your regular toothpaste and brush! LINHART Lip Balm was specially formulated using natural and organic plant based ingredients rather than additives. Because your lips are one of the most sensitive and absorbent parts of your skin, you should treat them with the utmost of care.
