The reviewer, Ashli, tried the Jillian Dempsey Spot Stick Concealer in the color 12. At first, she was unsure if she had the right shade because she couldn't see it on her cheek line. However, she realized that she was applying it incorrectly. To demonstrate its effectiveness, she drew a tattoo on her arm and used the concealer to cover it up effortlessly. The product provided full coverage with just a few strokes and blended seamlessly. Ashli was impressed by its ability to conceal tattoos, highlighting its effectiveness. Overall, the Spot Stick Concealer by Jillian Dempsey seems to be a reliable and high-performing product, offering great coverage and a natural finish.
