Confused about cushion shades

The shades for korean cushions usually aren't too different across brands (although there are some brands known for being lighter or darker than others) so it's typically still safe to choose the same code. Which means if you use No.19, you can get the same for other brands or go a shade lighter/darker. But TirTir is an exception. Their shade ranges and undertones are different and more diverse. I think the best way to test TirTir cushion foundation shades is to get the sample trial kit which they also sell. Since you can't try them out on your skin, I recommend searching online for foundation reviews and shade swatches to compare with your own skintone or existing foundations. There are lots of comparison swatches online, especially on reddit and tiktok.

tirtir’s mask fit red cushion line is known to oxidize really badly, and from what i know, I don’t think there’s anything lighter than a 13c? or there might be maybe a 10c, im not sure. tirtir did work with an albino creator to create her perfect shade, and it worked great for her. use findation.com, it’s super helpful🥰
