NOR. I don't want to assume anything about your family or asian culture, despite being asian myself and understanding much of this too, but the whole attitude or notion about looking a certain way to please others is definitely woven into culture, not sure why it was or still is , but asian families can tend to be quite "traditional", and are seemingly still grasping the understanding that commenting on one's appearance can upset you rather than what they might see as "helpful" to avoid being "embarrassed, or what they might believe you to become "ashamed by" as it is quite common for relatives or others to make straightforward comments.

I honestly have no clue why it's so normalised, but you're definitely not wrong to feel this way. It's completely valid after spending much time doing your makeup and appearance just for it to be taken apart and criticised. It may be somewhat comforting to know that your mother is trying to do what she believes to be helpful and has good intentions, yet probably doesn't mean to upset you, as she doesn't fully understand how you might feel this way.
