Overall, it’s a functional tie (both score 84) because these NYX products target different needs. NYX Lip IV is the better pick for a glossy lip look with a stain payoff, leading on beauty result (88), finish quality (90), comfort (88), and application (89). Its main limitation is shade expectation—several reviews report swatches don’t match real-life color—and wear can vary with eating.
NYX Mineral Matte Finishing Powder is the better pick for setting makeup and getting a natural matte finish, with excellent value (90) and slightly higher effectiveness (87). Its main limitation is shade match/inclusivity inconsistency, plus a specific flashback mention. Choose based on whether you’re improving lips or your base.
