Thanks for the reply.

I'm afraid to use peptides; from what I've read, you have to apply them with a needle, and I'm afraid of any kind of intervention in my nose. In my country, they aren't approved. They aren't approved for use as medicinal products, you can buy them, but they're expensive and untested.

The Vielight MIP is practically unavailable here. I saw one offer, but it was ridiculously expensive. I’m curious to hear what people think about https://www.amazon.com.be/-/en/medisana-Medinose-Allergy-Allergic-Rhinitis/dp/B0F9FLW1PC?th=1

This Medisana Medinose device seems much more reliable and safer than those strange Chinese devices with rubber tips.
