Yes, we recommend always washing your hands after using any topical muscle or joint gel, including HEMPE Hot and Ice Muscle & Joint Gels.Our CBD muscle gels contain active ingredients and compounds that can be absorbed through the skin and may cause irritation or discomfort if they come into contact with sensitive areas like the eyes, mouth, or other mucous membranes.Washing your hands after applying either gel also helps to prevent accidental transfer of the product to other parts of your body or surfaces, reducing the risk of unintended exposure.
