葡萄籽萃取 Grape Seed Extract × 皮膚老化
The human evidence for oral grape seed extract on skin aging is too weak and indirect to support even a C grade.
The human evidence for oral grape seed extract on skin aging is too weak and indirect to support even a C grade. The only single-ingredient human trial (PMID 15597304, 2004) is a small open-label uncontrolled study of n=12 women that targeted chloasma/melasma hyperpigmentation, not photoaging, wrinkles, or skin elasticity, and is at high risk of bias. Examine's only matched outcome (Hyperpigmentation, grade C, 1 study, n=12) is an acknowledged fuzzy match because Examine has no dedicated skin-aging or photoaging outcome for this intervention. Studies on wrinkles and dermal density use multi-ingredient supplements in which the grape seed contribution cannot be isolated, and a 2025 review confirms most anti-aging evidence is in-vitro or animal-based and explicitly calls for clinical validation. No regulator (EFSA rejected all grape seed claims; FDA, WHO, NHS, TFDA give no endorsement) and no dermatology body (AAD does not list it among recommended anti-aging interventions) supports this use. With no controlled trial and no authoritative endorsement, the honest verdict is insufficient/inconclusive evidence (U).

台灣美妝/保健社群（PTT BeautySalon 為主）對葡萄籽萃取的討論主要聚焦在『口服美白與抗暗沉』，幾乎不談膠原蛋白生成或抗皺等真正的抗老機轉。多數心得偏正面，常見『皮膚變亮、暗沉改善、粉底白一階、黑眼圈變淡』等主觀感受，且普遍搭配維他命 C 一起吃；但也有不少人反映吃了爆痘、無感。資深鄉民與引用食藥署的留言則強調防曬、睡眠、作息比吃保健品更實在，並提醒口服保健品法規上不得宣稱療效。整體屬個人經驗分享，非研究證據。
分歧偏正面（多數反映皮膚變亮、暗沉/黑眼圈改善、需搭配維他命C；少數反映爆痘或無感而停用，效果多為主觀感受）
- 臉部爆痘/長腫痘（最常見負評，尤以美安款被點名）
- 部分人吃了完全無感而停用
- 合併高劑量維他命C的腎結石/過量疑慮（鄉民自我提醒）
- 空腹服用腸胃不適（少數提及）
依論壇被提及頻率，非銷售或品質排序。
- Swisse（康是美有售，社群常推、多靠代購壓價）
- 美安 MarketAmerica OPC（討論度高但多人反映爆痘）
- DHC（常與其維他命C/E一起被提及）
