Yeah sure. Leahs beauty was marred because she cried so much, veinei Leah rakos. She was different than Rochel, Rochel was destined to marry Yaakov and as he was an Ish Tam, she was a tzaddekes from the beginning.
Leah was meant to marry Esav as she had a special ability to transform him -Dina inherited that ability which was why she went out to try to convert /educate the daughters of shechem. As Rashi says, kima kbita she was like her mother who had this incredible power to transform reshaim to tzaddikim. Which is also why Yaakov was punished for withholding her from Esav. Because she could also have caused him to do teshuva.
However, leah understandably did not want to marry Esa, and cried and begged Hashem to allow her to marry Yaakov. Even though she was not his true zivug she succeeded in her tefillos and through her constant tefillos elevated herself through humility and avoda to marry Yaakov. So she had the bitterness of a baal teshuva which is why her beauty did not radiate as much as Rachel s did.
Of course it goes without mention that as she worked so hard on herself, her spiritual level was even higher than Rachel . She merited to have half the shevatim and ended up being the wife that Yaakov spent most of his life with.
