The TKTX numbing cream is designed for temporary use, and it's important not to overuse it. Typically, it is recommended to apply the cream for up to 1-2 hours at a time, depending on the specific product and the area being treated.

As for continuous use, it’s generally not advised to apply TKTX numbing cream every day in a row for extended periods, as the skin may become sensitive or irritated. To ensure safety and effectiveness, it’s best to follow the guidelines on the packaging or consult with a professional (such as a tattoo artist or healthcare provider) for personalized advice.

If you're using the cream for tattooing or a similar procedure, some people might apply it on consecutive days, but only if they’re using it in short intervals and giving their skin time to recover between applications.

For the best results and safety, I recommend checking with the product’s official guidelines or a medical professional if you plan on using it frequently or for multiple days in a row.
