Beauty has two definition, our outer beauty and inner beauty. Outer beauty is our appearance, what can be defined as our eyes, lips, smile, hair, body and etc. It can be what is aesthetically pleasing to one's sight, and catches our attention. Everyone has different opinions on what they consider "beautiful" but that opinion can be influenced by the media and societal standards. Then there is the important side of beauty which is inner beauty. Inner beauty can be defined as our personality. A thing that can't be materistically defined, and captures you spiritually. That could your compassion, care, or kindness.
Beauty is in the eye of the beholder. Everyone's beauty should be accepted by society.
