蝦紅素（蝦青素） Astaxanthin × 皮膚健康
A 2021 systematic review and meta-analysis (PMID 34578794) found statistically significant improvements in skin elasticity (SMD 0.
A 2021 systematic review and meta-analysis (PMID 34578794) found statistically significant improvements in skin elasticity (SMD 0.77) and moisture (SMD 0.53), but no effect on wrinkle depth, and the elasticity result carried high heterogeneity (I-squared=75%). The underlying RCTs are tiny (n approximately 8-41 per study), demographically narrow (mostly healthy Japanese women), and the review authors themselves flagged that positive results may be influenced by commercial interests, since the trials were overwhelmingly funded or conducted by the astaxanthin industry (Fuji Chemical / FUJIFILM / AstaReal). A 2025 independent academic meta-analysis (PMID 40761858) explicitly judged the photoaging evidence insufficient to recommend astaxanthin. No regulator endorses an efficacy claim: EFSA non-authorised every astaxanthin health claim including UV skin protection, and no dermatology society (AAD) endorses it. Examine's grades are split (B for elasticity/quality, D for wrinkles and skin dryness on the largest pooled dataset of n=609). Taken as a whole this is a genuine but weak, small, inconsistent, and severely COI-contaminated evidence base, which maps to grade C, not B.

台灣社群（PTT 美容/regimen/藥師版）對蝦紅素用於皮膚多持正面但溫和態度，鄉民實測多反映膚質變細緻、較有彈性，常搭膠原蛋白；唯討論被白蘭氏等複方產品推薦文與商業媒體業配大量污染，多數人提到蝦紅素時其實是討論護眼，純皮膚向心得相對較少。
多數正面但溫和：實測者多反映皮膚變細緻、較有彈性、咕溜感，搭配膠原蛋白評價更好；少數對成分過敏。整體屬主觀體感而非顯著療效共識。

- 高劑量長期服用皮膚輕微橘黃色調（停用可恢復）
