Sun Squares, and more Sun Squares.
You can do Venus Square for beauty, but also much more importantly as your mental state suggests, a Sun Square to increase confidence and self-acceptance. The perception of "ugliness" can be tied to your Solar chakra (ruling self-steem) and not just literal "Venusean" features. Building up self love and confidence might as well make yourself and other find literally more attractive - this is not just "self-help" book bullshit of loving yourself just because, but actual practical reallity you must practice and apply consciously, and consistently daily.
In other words, a person with more confidence and self love (Poweful Sun) might - by default - make decisions, even unconsciously, that will increase their beauty and attractiveness despite of physical conditions, and transpire the idea of beauty to themselves and others - Ie., a more Bright and "Solar" person. You might have observed this in literal reality as ugly people who think they are the hottest in town, attracting hot partners - As if the "Universe" (quite literally) is making an uglier person more attractive, while the sexier Venusean person who is all but idealism, doesn't try to have any self-love and social interactions, is left wondering why they feel ugly and don't attract anyone. Besides the said Spiritual workings, make the conscious decision to love yourself more, as a meditative exercise and actions.
