Anecdotally, the biggest change that made a difference for me was switching to a more natural deodorant (Dr. Schmidt's bergamot+lime) from some of the big brands. I used to be able to smell body odour by the end of the day or go into a panic if somehow I forgot to apply in the morning. The odour has drastically been cut down, even if I did not apply the deodorant.
Apparently, when switching to natural deodorant it's supposed to get worse before it gets better which didn't happen for me.
I've asked my partner who has a pretty sharp nose and she agrees with me.
I very much appreciate the simplicity of the site, too many similar sites have thumbnails and a lot of extra information that deters from the information of what I really want to see (what the video is about).
