When is the last time you really thought about the product you are applying under your arms? Have you ever got to 2pm and wonder why you need to reapply? Or worse, have you noticed sweat marks on your silk blouse when you arrived at work?
Deodorant, which is usually our 'go-to', actually shouldn't be used to help with your sweat. Instead of doing the job you think it should be, deodorant only masks the smell associated with sweat and doesn't help to control it. Confused? I'm not surprised, as not many people realise that your dermatologist is the expert to speak to when it comes to sweat.

Question: Why do we often have to reapply our deodorant throughout the day?
Dr Karl Ng: Most deodorants work by blocking the sweat pores. Some contain Aluminium but are quite safe to use. These deodorants or antiperspirants lose their concentration on the skin (from contact with clothes, sweating it off) and don't work as well unless they are reapplied.
Question: Should we see sweat marks on our silk blouse after applying anti-perspiring deodorant?
Dr Karl Ng: Sweat marks may be either due to the colour of water/sweat on a fabric especially darker fabrics, or they could be because of the antiperspirant. Unusually they may be due to sweat but that is usually not of a very strong tinge. The antiperspirant often leaves a white mark, and this could be alleviated by the varieties that promise 'no white marks'; alternatively, some people don't even need antiperspirant, but have worn it out of habit!
Question: What is the difference between deodorant, antiperspirant and clinical antiperspirant?
Dr Karl Ng: Deodorant and antiperspirant are virtually the same thing. They attempt to dry up sweat. However, some may have fragrance to mask anybody smell.
