CitiSuper has Avalon Organics and other organic brands. Wing On carries Weleda. You can find Stella McCartney's organic skincare line at Lane Crawford. Then there's the Organic Pharmacy products, available at Harvey Nichols and IFC.
Have you tried Julique? They are an australian brand and have been around forever. I have been using their products for years and they are beautiful. Their website is www.julique.com.au and you can buy online. They have everything from skincare/haircare to aromatherapy oils.
In Silvercord Center in Tsim Sha Tsuin on Nathan Road (but i guess in Central as well) there is a beauty salon that sells Jurlique, Dr. Auschka, etc. usually with a discount. Dr. Auschka are still more expensive than in Europe, but less than Lane Crawford & the likes
Can't remember the name of the Beauty Salon: it's not in the main shopping area, but in one of the towers.
A lady usually gives away leaflets under the "bridge" of HaiPhong Road for face beauty routine at around 180 hkd with Jurlique product (utter bliss! too bad the normal price is 450 hkd)...
Lots of Australian brands are also in Organic skincare, worth a look.
Usually buy my welleda product directly in Europe.
mmmm..... try the "expat going home for holiday" or on a break in Hk thing or friends visiting to get your hands on it, maybe ?
Sorry i've got no idea about shipping in SH....
have you tried Sanctum -a yummy certified organic range from Oz - they are in threesixty and on the web too - they might post to you, be worth asking
they are opening an organic spa here in hk soon too
