Sorry Avalon, can't help either. Your product may still be available in another country, or maybe someone has some old stock and is sellig it on ebay.
Perhaps you could go to a nice big department store or a local beautician and get some advice/recommendations/samples to try for alternatives.
It's not only cosmetics that they discontinue (I can think of 3 great products that my usual cosmetics firm has stopped making which I loved) - it's all sorts of other things, too (washing powder, some food items in certain flavours). But often they then bring out a new version later on, sometimes under a different name, which may even be better.
