omg that happens to me in sooo many different mirrors like at the front of our house it make me look ugly but in the bathroom i look better, i think its the lighting and if the mirror has a slight bend in it too
some mirrors are slightly bent when they made them. its partly the lighting on you and the mirror
Unfortunately, they may be etched due to the minerals constantly hitting the window (mine were). You can test it by taking a razor blade to the window and if it scrapes off, they are not yet etched if it doesn't they are and there is no way to remove...
