How long does it last?

picture and info from here

Have you seen this picture before? I've seen it loads of times, but never really noticed it. Turns out that it's the equivalent of an expiry date for cosmetic items. On the picture there will be a number followed by an M; 12M means that the product has to be used within 12 months of opening it.

After finding out about this, I checked all my bottles/tubes for this symbol. I found it on my moisturiser, shampoo...basically on the stuff I bought in France, but not those I had brought from Malaysia. So maybe it's a European thing...let me know if you find this on any Malaysian stuff!

And here's a little tip I got: Keep store bought or home-made cookies fresh by adding two slices of bread to the cookie jar.
It's pretty logical when you think about it...bread absorbs moisture, doesn't it? (I haven't tried it though...)
