We should all try to do our bit in terms of recycling, sustainability etc and generally being nice to the planet and our bods, so buying products that help in this goal should be encouraged. I bought 4 of the deodorant sticks after reading they're expected to last 3 months each. I thought if they do last and actually work as intended then the huge cost would balance out and I'd happily continue to buy them. First impressions are mixed. Out of the bag, I thought these were travel versions. They are tiny. The smell is subtle but pleasant and that's fine. But after using them, I really can't see how these will last 3 months. I know it says to use sparingly and I'm trying but even so I'm concerned that they won't even last the month. They seem to work, as a shield against the whiff but only time will tell whether they go the distance as my pits feel like I need to reapply. I'll update if possible in the future time.
