The risk is probably minimal, skin is one of the fastest regenerating organs with absolute tons of extra regulation on the replication cycle of the cell. In the grand scheme of things you’re not going to significantly alter the biological age of your skin. Also if you were to begin to develop skin cancer on your face that wouldn’t be terrible, there are lots of non-surgical options to treat small melanoma and non-melanoma skin cancers (which should be small by the time you notice them considering you look at your face daily).
Get your hair removal and make sure to continue applying your daily sunscreen, you’ll be fine.
