Hello ^^
Based on the contents of the many inquiries, I made a wise use of KORHINA.
It is recommended to use it at intervals of 1 to 2 hours.
At the beginning of sneezing, it is recommended to remove the runny nose and use it for 15 to 20 minutes.
Likewise, if you sneeze and runny nose again in the early stages, it is cumbersome, but if you use it for 15-20 minutes after removing the runny nose again, the sneezing and symptoms may subside more quickly.
Occasionally, if you use it for a long time, you may feel dryness in your nose.
Children under 6 years of age are recommended to be treated under the guidance and observation of a guardian. If you are pregnant or lactating, please be careful when using the device unless absolutely necessary.
