25 white male that currently has patches on his face of a lighter skin tone. Its as if someone took an eraser to my face. What could this be?

Pityriasis alba. Sounds like the pale areas people can get as a result of dry skin and inflammation. Pigment cells temporarily go away, resulting in pale patches. Things that help--1) gentle, unscented cleanser. 2) good moisturizer, like cetaphil & others. 3) gentle cortisone, like Hydrocortisone cream, or preferably ointment, to resolve any residual inflammation. Color returns gradually. Vitiligo possible also.
Light areas. Changes in skin tone (hypopigmentation, in this case) may be caused by vitiligo -- i recommend a visit to your doctor, who may send you to a dermatologist.
