Do you look 4 times better when you look in the mirror?

No. You look exactly as you are when you look in the mirror. The mirror is a reflection on how you look. You do not look better or worse than when you look in a mirror. A mirror is a flat surface, and you have curves, so the mirror will not reflect your curves, but, unless it's a "fun house" mirror which is designed to distort how you look, almost all ordinary mirrors reflect exactly how you look. No better, and no worse.
