Best way to find same cushion foundation shade across different brands?
Hi everyone! Ever since my current cushion foundation ran out, I've been trying to find a new one, but shade matching has been a struggle. My current foundation (Banila Co Essence Skin Pink Cushion in 21 Rosy) is a perfect match, so I've been trying to base it off that.
However, all the numbers/labels seem inconsistent between brands, and even within the same brand (for example Banila Co), shades look completely different! For cushion foundations, the added step of oxidation (please correct me if that's wrong), makes finding a shade match even harder.
I know I could try to find another foundation from scratch, but I was hoping that having a foundation that already works would make this process easier. Is there any quick, reliable way to find "shade twins" for cushion foundations across different brands? Any help would be very appreciated!
