I found a very good organic skincare "Cocokind" in New York but they do not sold in HK nor can I buy it through internet. However, a few items of their products can be obtained through "IHerb" (free shipping for purchase over US$40.) I ordered a few items last week and they arrived HK in just 2 days which is perfect.
The turmeric that I bought from O'Farm is HK$46 but through "IHberb" it's only $32 which is much much cheaper. There are thousands of items there including supplements. Have a look.
