Oh I can totally relate! If I forget my lip balm I end up buying a new one and have so many floating amongst bags, pockets and rooms in my house! Once or twice a year I have a bit of a cleanout and mourn the loss of the lip balms as the older ones get put in the bin. I get a bit paranoid about bacteria on them, you know?
At the moment I've got the following on the go:
Jane Iredale Sheer Lip Drink.
I actually got this as a mini sample ages ago from Adore and it's a winner! No colour and really moisturising. I keep it beside my bed for pre sleep application.
Jane Iredale Just Kissed Cheek and Lip Stain.
Not as moisturising as the lip drink, but the super subtle colour is handy for a non lipstick wearer like me. It doubles as cheek stain which is a nifty two-in-one if I need to throw something in my bag for the day.
Weleda Lip Balm in Rose.
I like the squeezy applicator on this one. It's thick with some colour to give my lips a little oompf. It's a little too sticky for my liking, but it's highly moisturising and does seem to stay on for a long time which is probably a good trade off.
The other product I'm currently using for dry winter lips is not a lip balm at all but the Cosmedix Rescue Balm. This stuff is an absolute saver when my lips get super dry and sore during a week or so of winter. I also use it on flights and as the occasional overnight treatment for my entire face (and lips!) in winter. Super hydration.
