Generally, the effect of cooling patches can last for 4 to 8 hours.-When using cooling patches, pay attention to the product label and shelf life, and avoid applying to the eyes, mouth, nose or wounds.-If the skin is allergic or the fever does not subside after use, stop using it immediately and seek medical attention.
