Are you familiar with the Jung Saem Mool Skin Nuder Cover Layer Cushion? The reviews were all so good that I bought it with high expectations. Since I usually use shade 22, I purchased shade 22 Light. It was darker than what I usually use, and it felt like the color changed over time. Also, the cushion didn't apply well, which was disappointing. That is why I chose this as the worst cosmetic product.
