Hi, how are you?
In this issue, we will explain how much sun protection value increases when using a sunscreen with dispersion compared to using powder.
It is commonly known that using sunscreen in the form of a dispersion is more effective in enhancing the sun protection performance of sunblock products compared to using sunscreen in powder form.
We have confirmed that when using the same ZnO contents, sunscreen in dispersion form provides over 30% higher SPF compared to sunscreen in powder form through internal in-vivo test.
The reason for the improved sun protection efficacy when using a dispersion can be explained through the microscopic images.
When using a dispersion, the sun protection product is evenly spread without aggregation and this even distribution leads to the enhanced sun protection efficacy.
Therefore, it is essential to incorporate a dispersion to create sunscreen products with high SPF and PA level using only physical UV blockers.
The dispersion products currently available from SUNJIN BEAUTY SCIENCE are listed below. You can choose the appropriate product based on the formulation and usage. Furthermore, in addition to the listed products, we also manufacture customized dispersions according to the needs of the clients.
