Review (3/5): Product works but could use improvement in the way it smells.
I decided to try Lume because I hate the way my old deodorant cakes under my arms and embeds into my clothing. White clothing turns yellow and is quickly ruined. Darker clothes show the white residue as it has worked completely into the fabric. By the end of the day, a weird funk develops that's like a mixture of sweat and deodorant that's rather off-putting.
Lume does last the full day, but I wouldn't say it lasts 72 hours as advertised. The performance is satisfactory and it seems to solve the caking issue. The end of the day funk is less noticeable. So far it's a win.
My only complaint is the smell. There's a weird undertone that is a bit repulsive. The first time I tried it, I had to wash it off as the smell wouldn't go away. The second time I tried it, I used very little product. Drawing up maybe one millimeter of product. No more. The strange smell was much less noticeable and even went away fairly quickly. It still prevented body odor for a full day. So I think the trick to avoiding the underlying odor of, I am assuming, the active ingredient is to use very little product.
Ideally, we wouldn't have to deal with that smell at all. The product could use some improvement as a result.
