The warming sensation is created by a combination of ingredients in the formula: camphor, menthol, cinnamon essential oil, and ginger oil. These are intended to stimulate local microcirculation during massage, helping a tense area feel looser. This is a common effect in topical products designed for muscles and joints.
Because the formula contains these warming and spicy essential oils, it may be too intense for sensitive skin. It should not be applied to irritated skin or mucous membranes. If you are prone to skin reactions, the safest approach is to test the cream-balm on a small, discrete area of skin first. The niacinamide in the formula helps maintain the skin barrier, which is useful if you plan to use the product regularly.
For all users, it is standard practice to wash your hands thoroughly after applying any product containing camphor or menthol.
