It’s not uncommon for people to feel as though their deodorant is no longer as effective as it once was.
The most important step to answering this question is pointing out the difference between antiperspirant and deodorant.
Antiperspirants block sweating, deodorants mask the odor.
The recipe for odor is sweat + bacteria = odor.
With my quick primer out of the way it’s easier to understand what happens when a deodorant stops working.
Either there is more sweat than before or more or different bacteria in the area.
- If there is more sweat, then the result will be a “damp” feeling along with the odor.
- If there is more odor than generally people will feel “dry” but know there is an odor.
If there is a damp feeling we have to re-evaluate our game plan with sweat. We either increase the strength of the antiperspirant or choose an alternate method of blocking sweat.
If there is a dry feeling with associated odor, then it may help to choose one of a few options. Either change up your scent choice, consider an antibacterial soap or lotion for a week or two to cut down on bacterial overgrowth, or consider using a mild scrub in the to gently exfoliate any buildup of bacteria.
