异栎素 × 紧致

EMIQ（酶改性异槲皮苷）在体外减少胶原损伤，临床显示改善皮肤弹性，支持紧致功效。

EMIQ (enzymatically modified isoquercitrin) reduced collagen damage in vitro and improved skin elasticity in clinical trial, supporting firming efficacy.

异槲皮苷预处理有效防止UVB诱导的胶原纤维降解，表明其具有紧致功效。

Isoquercitrin pretreatment effectively prevented UVB-induced collagen fiber degradation, indicating firming efficacy.

异槲皮苷是主要成分之一，提取物促进成纤维细胞增殖和胶原沉积，支持紧致功效。

Isoquercitrin is one of the major compounds, and the extract promoted fibroblast proliferation and collagen deposition, supporting firming efficacy.

异槲皮苷是主要抗氧化成分之一，且水提物显示抗衰老作用（增加I型和III型胶原），但未单独测试异槲皮苷对胶原的影响。

Isoquercitrin is one of the major antioxidants, and the extract showed anti-aging effects (increased collagen types I and III), but isoquercitrin was not tested individually for collagen effect.

异槲皮苷上调I型前胶原、HAS2，下调MMPs，表明其促进胶原合成，支持紧致功效。

Isoquercitrin upregulated type I procollagen and HAS2, downregulated MMPs, indicating promotion of collagen synthesis, supporting firming efficacy.

异槲皮苷（isoquercitrin）作为成分之一被鉴定，但摘要中未单独测试其对胶原合成的影响；主要活性来自老鹳草素和furosin，因此异槲皮苷的紧致功效证据不足。

Isoquercitrin was identified as one of the compounds, but the abstract does not test its effect on collagen synthesis individually; the main activities are from geraniin and furosin, so evidence for isoquercitrin's firming efficacy is insufficient.

异槲皮苷（化合物2）未抑制MMP-1表达或弹性蛋白酶活性；活性来自其他化合物。

Isoquercitrin (compound 2) did not inhibit MMP-1 expression or elastase activity; the activities were from other compounds.
