Since moving to Korea, I feel a lot more pressure about my appearance than I ever did back home?

This hits a lot of newcomers, and you are not imagining it; appearance is talked about more openly here than in many countries. Comments on weight or skin that would feel rude back home are often meant as casual observation or even concern rather than insult, though that does not make them comfortable. A few things helped me. First, do not take the comments as a verdict on your worth; they are partly small talk and partly a very grooming-focused culture, and coworkers spending on skincare is normal here rather than a standard you must match. Second, you can set gentle boundaries; a light, smiling reply that you are happy as you are, or just changing the subject, works, and people usually move on. Third, the flip side is that Korea makes self-care easy and affordable if you want it, with great cheap skincare, dermatology, and fitness options, so you can engage on your own terms without feeling pressured. The beauty standard here is specific and narrow, but plenty of foreigners and Koreans live happily outside it. Take what is useful, like the skincare and the walkable healthy lifestyle, and let the rest go without internalizing it.
