Since yesterday i noticed that every cream or product i apply to my face tends to burn slightly or sting my cheeks (always in the same area) without any redness, what could cause this? i've used these creams before. what can i do to prevent this?

Have you changed anything else you are applying to your face? Different soap, for example? Different make-up? It sounds like you are reacting to something-if the creams are not new, perhaps something else is irritating the skin and then the creams sting. If nothing you are applying to your face is new, perhaps seeing a dermatologist is the next step if this continues. Good luck!
