PROBLEM TO BE SOLVED: To provide a lip dullness correction agent capable of improving lip dullness without giving an unnatural impression.SOLUTION: A lip dullness correction agent comprises the following active components (A) and (B): (A) a red pigment which is dispersed in polybutene at a concentration of 0.1 mass% and coated at a thickness of 400 μm onto a glass sheet where the maximum value of spectral reflective strength in the 500 nm to 720 nm region measured on the white part of hiding rate test paper is at least 2.5 times that of the minimum value； (B) one or two powders selected from the group consisting of red interfering tabular powders dispersed in polybutene at a concentration of 1 mass% and coated at a thickness of 400 μm onto a glass sheet where the maximum value of spectral reflective strength in the 500 nm to 720 nm region measured on the black part of hiding rate test paper is at least 2.5 times that of the minimum value.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】不自然な印象を与えることなく口唇のくすみを改善することが可能な口唇のくすみ補正剤を提供すること。【解決手段】次の成分（Ａ）及び（Ｂ） （Ａ）ポリブテン中に０．１質量％濃度で分散させた分散物をガラス板に厚さ４００μｍで塗布し、隠ぺい率試験紙の白部上で測定した５００ｎｍ～７２０ｎｍの波長領域における分光反射強度の最大値が最小値の２．５倍以上となる赤色顔料 （Ｂ）ポリブテン中に１質量％濃度で分散させた分散物をガラス板に厚さ４００μｍで塗布し、隠ぺい率試験紙の黒部上で測定した５００ｎｍ～７２０ｎｍの波長領域における分光反射強度の最大値が最小値の２．５倍以上となる赤色干渉板状粉体よりなる群から選ばれる１種または２種の粉体を有効成分とする口唇のくすみ補正剤【選択図】図１
