Local skin irritation every now and then

I am living in a climate with hot summer weather, a lot of sun and near to the sea. A month ago I switched to this routine, but I started to notice that when I apply the Umbra sunscreen (or at least I think that is the trigger) my face starts to feel irritated and slightly burning, especially on my forehead and around/under my nose. I don’t know if my new routine involves too many products that can cause sensitivity or that it is the sunscreen of which I though it was a safe one to use. I top my evening routine also with 100% organic rose hip seed oil from the ordinary.
