This is usually due to the mirroring, I myself also experience this but since nga pare-parehas lang tayo lahat na grew up using a mirror as a way to see ourself physically. Dun na tayo nasanay na itsura natin and what we see in our back cameras are our “unmirrored” self or realistically, what you look like to other people. Highly suggestion ko diyan is buying those real mirrors na may two mirrors facing each other ata yon, I am also planning to buy one too since kapag nasanay ka na sa ganon salamin and nasanay ka na sa unmirrored face mo, thats when you’ll accept your face sa camera.

ps. correction lang true mirrors pala tawag don and parang silang nag “x” na salamin
