Ugly side profile, how to improve? What procedures would balance my face? 23 years old and weigh 49kg. (Photos)

Your nose and nasal hump can be improved with rhinoplasty. I would recommend starting with a consultation with a board certified facial plastic surgeon that specializes in rhinoplasty surgery. 
I would recommend writing down the following questions before scheduling your consultation:
1. Are you unhappy with the tip of your nose? 
2. Do you feel that your nose is too wide? 
3. Do you want to make your nostrils smaller in appearance? 
4. Are you looking to decrease the general size of your nose?
I hope some of these questions will help you pinpoint what it is that you don't like about your nose.  Cost will vary due to many factors including: facilities fee and anesthesia fee. I wish you the best as you research your options when scheduling a rhinoplasty consultation.
Sincerely,

Hello and thank you for your question. Based on your
photograph, you may benefit from a tip refining rhinoplasty and a nasal tip deprojection to make the overall size of your nose smaller.  A chin implant can be performed at the same time for
improved jaw line contour.  I always use a medpor implant with screw
fixation, which stays in place over time.  A silicone chin implant has a
high rate of malrotation over time.  Make
sure you specifically look at before and after pictures of real patients
who have had this surgery performed by your surgeon and not just a computer
animation system. The most important aspect is to find a
surgeon you are comfortable with. I recommend that you seek consultation with a
qualified board-certified plastic surgeon who can evaluate you in person.
Best wishes and good luck.

I agree a rhinoplasty could help to soften your profile view.  I recommend you consult with a plastic surgeon to discuss your goals further. Often you surgeon will be able to morph your photos to give you an idea of your appearance post surgery.

Emily,    Thanks for your question.  You are spot on with a lot of issues.   I think only taking the hump down would leave the nose too flat.  In your case some augmentation of the radix area (often with fascia or cartilage) along with slight bump removal are helpful.   It is important to maintain harmony with the nasal tip which may change with surgery depending on your goals, and some standardized photographs.  Regarding the occlusion and chin, I do think the chin is underprojected.  And you may benefit from a small chin implant at the time of nasal surgery (this is fairy common).  Balancing the chin with the nose will make the nose appear smaller and give a good balance to the face.  A consultation with standard photographs and an exam is best to give more details about what might be best in your case.Good luck.

Hi Emily!I would recommend consulting with at least two board certified facial
plastic surgeons. Following is what to be prepared to ask for during
your consultations:
1. Ask about his/her experience performing rhinoplasties.   This is
important to know since you want to ensure that the doctor has performed
enough rhinoplasties that he will be able to handle any issues that may
occur during your surgery. But don’t rely on numbers alone. Someone who
has learned to tie their shoes incorrectly may tie them that way a
thousand times. But someone who learned to tie shoes correctly may have
only tied them a hundred times. 
2.  Talk to previous patients. Your plastic surgeon should give you
the names and contact information of previous patients who have
undergone a procedure similar to the one you’re considering. Finding out
what a patient has experienced and how she feels about the results can
set your mind at ease and give you a good idea of what to expect.
3. Request computer imaging. Computer Imaging allows one to preview
one’s surgical results BEFORE the surgery.   One of the newest and most
illustrative tools that surgeons can now employ is the use of
computer-generated imaging (CGI) to illustrate the anticipated results
of a Rhinoplasty procedure. In previous years, both surgeon and patient
had to wait until the post-surgery swelling in the nose receded to see
if the procedure's results met with their expectations. Today, surgeons
can illustrate what the post-surgery nasal structure will look like with
the click of a computer mouse.  You can also use the computer imaging to show possible results for the chin implant and any other features you'd like altered. 
4. Get the surgical gameplan.  Every surgeon works in his/her own
way.  The consultation is the time to ask questions about what to expect
during surgery: What does your surgeon plan to do and how does he/she
plan to do it? How long will the surgery last? What type of sedation
will be used? Will the surgery be performed in her office or at a
hospital?  How long will it take to recover?  How soon after surgery can
you go back to work or exercise?  How will she handle your pre- and
post-operative treatment?  What is included in the cost of the surgery
and what, if anything, might be extra? Information should be explained
to you in easy-to-understand language. If you don’t understand
something, ask questions.
5. Discuss potential risks and complications. 
Assess your comfort level.  Once you have meet with prospective
plastic surgeons and interacted with their staffs, you have a pretty
good understanding of how plastic surgery can enhance your appearance
and what the doctor can and can’t do. You may have come to the
realization that each surgeon you consulted reached similar conclusions
about your surgery and the results you can expect. The computer images
you viewed may have been quite similar, too.  Take a deep breath and
examine your feelings about rhinoplasty and the surgeons you’ve met.
Good luck!
Dr. S.

Looking at your profile, I agree that modest hump reduction is advisable to create a more feminine appearance. In addition slight tip deprojection and cephalic (upward) rotation will also help to balance your profile. I do not think you need chin augmentation with these changes, as you nose will be more in balance with your overall profile. Good luck!
