The present invention relates to a skin composition which has an excellent effect on smoothing or repairing wrinkles. The composition comprises Palmitoyl Tripeptide-38 (Palmitoyl-Lysyl-Dioxymethionyl-Lysine) and Piper nigrum (Pepper) seed Extract which combination has been found to result in a synergistic effect on hyaluronan synthase 1 (HAS1) mRNA expression in human fibroblasts. The hyaluronan synthase is responsible for the synthesis of hyaluronan (hyaluronic acid) in skin. Hyaluronic acid is a constituent of the extracellular matrix of the skin and responsible for space filling, tissue repair and retention of moisture.

氨酰-二氧蛋
氨酰-赖
氨酸)和胡椒籽
提取物,研究发现这两种成分的结合可对人成纤维细胞中透明质酸合成酶 1 (HAS1) mRNA 的表达产生协同作用。透明质酸合成酶负责合成皮肤中的透明质酸。透明质酸是皮肤细胞外基质的成分,负责填充空间、组织修复和保持
水分。
