Salon System lash lift bottles

I have recently purchased these and trying to find out how long they last once opened as I can't find the info anywhere on the bottles or packaging?? Anybody know Please?

Use them as quick as you can, they never work aswell after a couple of uses. I stick to the sachets and use the empty bottle for patch tests and squeezeany leftovers in there.
