I've been taking long fast walks daily in the Georgia heat, it's great to stop the rash, really a game changerDermatologist recommended this product so assuming it's safer than J&J baby powder. Product seema expensive to me, but works excellent.I like the absorbent it gives. You don't know a lot, just a little will do.DKEEPS YOU DRY IN SPOTSGreat productI have been using Zeasorb for seven years and it works wonders, especially in the summer heat. However, I am very disappointed in the deceptive marketing. The last few purchases I made seemed to go very quickly, so today I decided to hold my containers to the bathroom light. Low and behold these “brand new” bottles are half empty. Unfortunately, I cannot find zeasorb in stores but I will not pay full price for these half empty containers. I am looking for another legitimate seller or if necessary I will switch to another product.I wish it was a bit less money, but the product does work for why it was produced.Best powder I have found.The powder itself is not good: it clamps together and can irritate the skin. I didn't notice that it's more absorbent than regular talc. There are better powders with ZnO and/or menthol out there. If you don't need these, buy just regular talc baby powder - will be cheaper.Used since dermatologist recommended in 2016 excellent for absorb sweat I tecommend tbiabproduct on my 4 order for this in those yearsWorks well, bit priceyNON-RETURNABLE ITEM. VERY EXPENSIVE TALC POWDER. BEWARE!!!IMy dad says that this product works well.
