Every time I take a bath the skin on my face (around my eye brows and nouse) comes off. Ist it serios? Or just a faze?

Normal. You likely have a lot dry skin in need of exfoliation and it is sloughs off when it becomes well hydrated during your bath. It is nothing serious.
Okay. A mild amount is okay. More likely to happen in winter especially w dry skin. Consider using a milder soap like dove or cetaphil and moisturizing after.
