weird reaction to skincare products?

so basically what happened is that i bought a new set of skincare, it includes a facial cleanser, toner, hydrating gel, charcoal mask. i used it for one night and the next day i was okay so i used it again but something weird happened. the next morning i woke up with a very itchy face but i didn’t care and just went to sleep until i had to wake up and go to work. when i came home and took off my makeup (with those products), my entire face had a rash and was burning/itching. now it’s been approximately 3 days and my skin is now very dry, scaly and i have a bunch of microscopic pimples. it never happened to me before and the set is supposed to be allergy friendly? it’s all natural. i have never used anything else on my face during those days. (note: i also used a primer from the same brand during those days) is it an allergic reaction?
