However, the powder particle size of these products has an important impact on skin irritation and discomfort. Generally speaking, the smaller and finer the powder particles, the less irritation and discomfort to the skin, and the better the effect of absorbing sweat and making the skin smooth. Therefore, it is necessary to test the particle size of talcum powder or anti-prickly heat powder.
