The 4-in-1 Pressed Mineral Makeup SPF15 by PUR was reviewed by Kristen in a video. Initially, Kristen used it as a setting powder due to the lack of coverage she desired. However, after receiving suggestions from viewers, she decided to give it another try with a denser and chiseled brush. Kristen found the product to be nice when used as a setting powder for her under eyes and shiny areas. However, since she already had a setting powder, she questioned if it was worth the price for that purpose alone. Kristen mentioned that she might try the product again for a full wear test. Overall, the 4-in-1 Pressed Mineral Makeup SPF15 by PUR seems to work well as a setting powder, but its coverage may not meet everyone's expectations.
