[Skin Concerns] I think I might have a niacinamide sensitivity. Anyone have similar experiences?

Beauty Tips For Body Care
I recently decided to try using EltaMD UV Clear again, and my skin has been easily agitated and flushing since doing this - for about 3 days now. I used to use this sunscreen regularly until I decided to simplify my routine when I found a sunscreen that could double as a moisturizer. And now I'm realizing that my skin had become a lot calmer since ditching the UV Clear which has 5% niacinamide.Basically I'm wondering if it's heard of to have a sensitivity to niacinamide by itself, because I don't think I'm using anything else that is known to cause reactions to it via interaction.My routine is below:AM:Cleanse face with AlboleneRemove Albolene with cotton pads + thermal waterApply Kiss My Face 'Face Factor' SPF 30 (until recent re-addition of EltaMD UV Clear)PM:Cleanse face with AlboleneRemove Albolene with cotton pads + thermal waterApply Avene Rich Compensating CreamApply layer of Noodle & Boo Ultimate Ointment (It's for babies :) but I bought it after reading the ingredients list and it's very calming to my skin.)
