All perfect praise be to Allaah, The Lord of the Worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His slave and Messenger.
First of all, we advise you to take it easy on yourself and not harm yourself by thinking about a matter which you have no hand in and making it among the whispers that may influence your thoughts and cause you an unbearable harm. You should preoccupy yourself instead with the remembrance of Allaah and with being grateful to Him, as Allaah ordered us; Allaah Says (what means): {So remember Me; I will remember you. And be grateful to Me and do not deny Me.}[Quran 2:152] There is comfort for the soul and tranquility of the heart in remembering Allaah; Allaah Says (what means): {Those who have believed and whose hearts are assured by the remembrance of Allaah. Unquestionably by the remembrance of Allaah hearts are assured.”}[Quran 13:28] Also, you should preoccupy yourself with what benefits you in this worldly life and in the Hereafter.
Furthermore, you should know that the real beauty is not in one’s features and good looks; rather, the real beauty is in one’s beautiful soul, good moral conduct and perfect manners.
As regards those who mock you, then you should not take this into consideration, as people barely like anything and they generally look for deficiencies. So, if a person is preoccupied by such people, he would die of sorrow. Hence, if someone mocks you, you may remind him of Allaah, and of the prohibition of mocking. Allaah Says (what means): {O you who have believed, let not a people ridicule [another] people; perhaps they may be better than them; nor let women ridicule [other] women; perhaps they may be better than them.}[Quran 49:11]
Besides, there is a Hadeeth of the Prophet which reads: "Do not glee at another’s misfortune as Allaah may relieve him from it and afflict you with it.” [At-Tirmithi who graded it Hasan (good)]
On the other hand, if there is a way for a natural therapy that turns the nose into a normal condition, then this is permissible as this is a kind of seeking treatment.

Allaah Knows best.
