Perri provides a comprehensive swatch comparison of the Triple Fix Serum Foundation in Porcelain color by LYS Beauty in their video review. They compare it to other popular foundations, such as Makeup Revolution Super Dewy, ELF Halo Glow, NYX Born to Glow, Smashbox, and Covergirl. Perri notes that the LYS foundation does a great job of color correcting and toning down redness in their skin due to its slightly yellow undertone. They mention that the shades from NYX Born to Glow are the closest match to LYS. Overall, Perri seems impressed with the foundation's performance and its ability to provide a natural-looking finish. However, they do mention that the ELF Halo Glow has a more peachy undertone. Based on Perri's review, the Triple Fix Serum Foundation in Porcelain color by LYS Beauty appears to be a reliable option for those looking for color correction and a natural finish.
