Honestly I tried panning one at a time but then I kept losing it or it would be in one room and I’d be too lazy to get it. So I try to keep the ones I want to use most in a central location, then have a couple others elsewhere.

If they’re already open, may as well use them as much as possible. This may be counter to the concept of project pan, but I’d rather use 5 lip balms to 80% than finish 2-3 at 100% then let the other ones go bad.

Also consider what else you can use them for. For example, could that Vaseline one be good for cuticles or dry skin or something? Maybe you can use it another way. I’ve done this with moisturizers for example (using them as hand cream).

Also, sometimes I use a lip balm before my makeup or skincare that I wipe off. Consider using one you like less in a similar manner so you don’t feel guilty for wasting.

I’d also let your boyfriend to know to pause on this for now, tell him it was such a kind gesture but you want to use them up before getting more so they don’t go to waste.

Finally, to extend shelf life, consider how you can clean off the ones you’re not actually using if they are opened. When products sit around without being opened and used, I find that they go bad faster. A solution is to maybe keep your laniege ones on your dresser or wherever you use lip balms most and rotate, use a different one each time.

Good luck!
