The super old school Sam Fong Hoi Tong powder by Sam Fong Cosmetic Co. Hong Kong. I like the packaging, it's so cute! It's amazingly still around without any changes to the packaging. And it only costs S$1.00 (about US$0.65). Our grammas and great grammas used these cuz as my mom said, they didn't know how to use western cosmetics (liquid foundation). This together with paper rouge. Actually it's just a white slab of calcium carbonate. And they say it makes your skin white (by that I think they mean fair but it makes you geisha white too). You can add water and use it as a mask. Some people use this to polish silver like how some people use baking soda to clean sterling silver.
I have 2 boxes at home. Not too sure if one is illegitimate or a parallel import but the differences show. The left one is the Hong Kong one which I bought from a Chinese medical store (Chinese instructions) and the right one is Indonesia/Kuala Lumpur import (English instructions) which I got from a makeshift store in a bazaar. The left one looks nicer of course. The side papers are gold shiny papers.
Check out the ingredients:
-Hong Kong: Calcium Carbonate, Talc, Fragrance
-KL: Magnesium silicate, Calcium carbonate, Talc, Methyl Paraben, Propyl Paraben, Aquademin, Fragrance
That's a whole lot of difference lol. The Hong Kong one is much smoother than the other one (which is grainier), and slab sizes are different. This may not be important unless you are allergic to the parabens? It's effective at keeping your face less oily in humid climate, but wear it at home lol. Or wait till the white is absorbed before you go out if you don't want to look like having flour on your face. I googled it and found places mislabeling it as rice powder... I wish it were! Unless calcium carbonate is rice powder... neh. And these sites are Ebay stores: some sellers probably copy-paste without verifying.Edit: Well I have been getting a lot of emails and views on this post, thank you! Yes there is a pink tinted version although it is very pink so I did not bother to try. I think they are the ones that come in the pink plastic cases. Ingredients and country of manufacture are unknown, maybe I'll update this post if I come across any. I currently don't use this anymore, though they are more readily available in Singapore stores. I think talc clogs pores and so have changed to something better - silk powder.
