Would your treatment be able to help me? I can barely breath through my nose because it's always slightly stuffy. I get periodic 24-hour "attacks" where my nose is extremely stuffy and congested, my throat itches and my eyes water and I feel fatigued. I've been to several specialists and gotten allergy tested but the tests came up negative. I even had my adenoids removed. I'm on zyrtec daily but nothing helps me. I don't have a deviated septum or anything of the sort - doctors are at a loss as to what's wrong with me.

Is your 100% plant-derived squalane made from sugarcane or olives?

The Ordinary + Hylamide offer a TON of vitamin C products. Which would you recommend for someone with fairly tough skin that isn't prone to much irritation? I'm currently trying to decide between the Hylamide's Ethylated 30% vs. TO's Vitamin C Suspension 30% in Silicon.
