Compared with other talcum I can say dermi cool works and on the same time is gentle on skin and have a very pleasant smell.
Controls sweat and very useful when its humid.
Doesnt darken skin or doesnt create any kind of red swelling as it doesnt block pores of skin completely.
Technically I had a good feeling about dermicool.
Using this product since 2012, prior to that I war using nycil as it was traditional and mom used to get that, but had a very harsh reaction and have heard from localities as well that nycil darkens skin tone.
