I have hairy arms and legs...as does my father! lol Asian countries are not free of acne and their health problems. When I was in China, I saw a number of teenagers with their share of bad skin. Although, in China, much like many countries in the world now, are inundated with Western style restaurants (McDonalds, KFC), so I'm sure that it's having that impact.
Buying fresh fish and eating it properly is not easy and not cheap. You also have to be wary of the levels of toxins and mercury in fish etc.
Jojoba oil and Emu oil should be non irritating and non-comedogenic to most people, even though most "comedogenicity charts" would disagree. Those charts are not the be all-end all guidelines to follow.
Like Misfits said, Olive oil can also be used, although I've never personally tried it out myself. Olive oil is often used as a nice massage oil and many people use it on their face as well.
Another (very inexpensive and effective and long-lasting) oil is Coconut oil! Just so long as it is extra-virgin and unrefined, then it will do wonders as a night time moisturizer. Many use it for during TCA peels as you need SUPER moisturization, and coconut oil definitely does the trick.
Right now I'm using emu oil as my night moisturizer, but it's expensive for the cost-size ratio. So I often switch it up with coconut oil: http://www.tropicaltraditions.com/skin_health.htm
Sunscreen is vital for the face, more for some, and not for all. It mostly has to do with long-term effects of intense sun blasting your skin. Sun is cause for hyperpigmentation in some people, and ESPECIALLY if you have existinging red/brown marks. It can make your skin tan unevenly.
Sun damages collagen in your skin, leading to wrinkles, sagging skin....but you see, this is mostly long term.
