I follow a few polish pages/influencers. They don’t look very similar when it comes to content.
One does releases based on popular shows/media and has wild names that come from the shows for example “What the fork?” For a Good Place collection. Lots of glitter/multichromal colors.
The other does a lot of branded edited reels that preview the next theme. They also do a lot of hi-def polish mixing content, which always does well. Lots of muted or nuanced bright colors that aren’t typically released in stores. They use a lot of local or indie sourced ingredients.
Both use small influencers to promote the polish and get brand pics. One does pre-orders for collections, which allows them to do constant new shades with guaranteed sales. Then a small amount goes on the website. Rarely there is a restock.
The other just releases online and restocks popular colors. Collections don’t get restocks.
Either way your brand either needs to showcase polishes that can be used for current trends or do drops. Otherwise, they’ll easily be drowned out by more popular indie brands like Mooncat, Halo Taco & Kathleen Lights brand.
