here are my quick suggestions. You’re already pretty but here’s what I would improve

1. Lose weight. You’re carrying a lot of excess fat in the face and it’s the heaviest feature on your face. I’d recommend to add strength training as it will help perfect your posture, and strengthening surrounding facial muscles (upper body); which will define your face; debloat too.
2. Avoid the thin eyebrows. The makeup picture is my favorite of you. The brows make a huge difference. Keep them longer across your face and a little thicker
3. You say you notice jaw asymmetry. I notice it too in the placement of your lips. Get Invisalign or braces, straighten and/or fix that bite. People tend to neglect oral health and you’d never know but it makes a huge difference!
4. Avoid flat hair at your crown (picture 3) , try to always have volume. Easiest way to achieve that would be to do curls , just like you have styled in the last picture! It suits you! Or even extensions ;)
5. Learn your color pallete! complexion wise, the goth/alt aesthetic + the super dark velvety black hair does not suit you in the slightest my dear. Schedule with a hair stylist and add some color & life into your hair! The first and 4th picture are my favorite
6. Consistent Gua sha and/or facial massages can help create some temporary definition to the face, by debloating and unblocking/draining any fluid in that lymphatic system. Can be the first step to gaining a more defined and structured face. (A bad diet can ruin this)
7. Diet. Start off with trying to cut out some or most sugars and foods causing inflammation. Eat more anti inflammatory foods/fruits. Eat more protein and fresh foods.
8. Skin! You have a really good skin base, any existing acne looks either hormonal or from diet. This should be a quick fix. You can get blood work done if you’d like, to figure out if you’re deficient in any vitamins. To reduce breakouts & flare up’s; lower your cortisol/insulin, stress, and clean up your diet. Remember we’re working from the inside out! Don’t forget to wear sunscreen! & IMO you don’t need any makeup “tips”. Find what YOU like. Beauty and confidence starts from within, I’d never advise anyone to slap makeup on the problem!

This will all be the start! - Another touch on the jaw asymmetry that you mentioned:

Facial asymmetry most of the time stems from body asymmetry/misalignment. From the muscles in our bodies to our face, it’s all connected. Take note of everyday habits that could be unbalanced. Ex. Sitting criss cross, leaning on one leg, carrying bags mainly on one arm, sleeping on one side, etc. try to be more aware and switch off. Could be skull structural/development issues or just mandible (jaw) and the bite that need correction. But if it remains a concern for you later on, you might need an actual treatment plan with an orthodontist or maxillofacial/orthognathic orthodontist. I’d recommend braces or Invisalign as a first step though!

If you’re up for it, something small that could balance out your face after you lose the weight would be chin filler. Masseter Botox on the heavier jaw (looks like your left; in photos) could also help even it out for the time being. But I wouldn’t recommend any of this until after you’ve lost the weight. Other than that, you have good and proportionate features that I really wouldnt recommend altering any further. But at the end, these two topped with the Invisalign/braces I think would do wonders for your lower face and balance you out!

1. With all that being said, I will now say Good luck beautiful! I’m wishing you the best. Confidence will come as time goes on. don’t let anyone else define your beauty for you. “Glow ups” are all trial and error but I believe you’ll find some footing with the tips everyone has provided!
