Can I use this oil on my face or other sensitive skin areas?

It is not recommended to use this camphor oil on the face or other sensitive areas of the body. The product is intended for external use on intact skin and its warming sensation is quite intense. Sensitive zones, which include the face, underarms, and groin area, are more likely to react strongly or become irritated. The "Important Notes" for the product explicitly advise avoiding sensitive zones. If you have generally reactive skin, it is prudent to first perform a patch test by applying a very small amount to a discreet area of skin, like the inner forearm, and waiting to see if any redness or discomfort occurs. Always use the oil sparingly and only on unbroken skin. Remember to wash your hands thoroughly after application to avoid accidentally transferring it to more sensitive areas like the eyes.
