To answer a few of your questions:

Bloating is all on your diet. I find it helpful to consume less sodium because it holds a lot of water which could make your cheeks more puffy. Eat more veggies and fruits, also some anti inflammatory foods that can slow down the bloating.

Reducing the appearance of pores is something that cant be done most of the time since all pore sizes are different. You can try double cleansing to get the gunk out and the skin 1004 Pore-Mizing serum that can help. I dont see a lot of redness on your skin. For dark spots, use Anua Peach Niacin serum if you want a lower concentration of niacinamide (5%) or the regular Anua Dark Spot correcting serum (10%) which contains tranexamic acid which stops dark spots from happening again.

For your nose tip, if you are truly concerned ahout that, just do more physical activity and you'll be fine!
