While there is no evidence to suggest it represents a threat, some folks are concerned about applying deodorant to their underarms immediately after shaving there. This goes for both deodorants and antiperspirants as well. Perhaps this concern is spawned from the fact that after shaving, the skin can be dry and irritated, and applying any sort of cosmetic or hygienic product to rough and perhaps lightly cut skin is going to result in an uncomfortable stinging sensation. This stinging sensation, while quite normal, may raise red flags with some people who interpret it as a signal from the body that it is somehow dangerous. It’s understandable that someone may think that but in reality, the stinging doesn’t mean anything other than your skin is a bit raw. Others suggest that applying to raw skin with perhaps a number of tiny cuts on it only helps any potentially dangerous ingredients infiltrate the bloodstream. The fact is however that there is zero conclusive evidence that any of the ingredients in today’s deodorants poses any risk to the body. Therefore, applying deodorant after shaving is a personal choice. If you are unconvinced, then wait an hour or two after shaving before applying your deodorant as this will give any microscopic cuts time to heal.
