乳鐵蛋白 Lactoferrin × 痘痘 / 痤瘡
結論:證據支持但有警示
證據基礎雖方向一致但規模小且陳舊:1 篇 2017 JDDG 系統性回顧加 3 篇 RCT/臨床試驗(2010、2011、2017,最大樣本 n=168),均為單一研究團隊取向、多為複方(合併鋅、維生素 E 或發酵乳)而非單方乳鐵蛋白,且 2018 年後無新 SR/MA 或 Cochrane 回顧。

證據基礎雖方向一致但規模小且陳舊:1 篇 2017 JDDG 系統性回顧加 3 篇 RCT/臨床試驗(2010、2011、2017,最大樣本 n=168),均為單一研究團隊取向、多為複方(合併鋅、維生素 E 或發酵乳)而非單方乳鐵蛋白,且 2018 年後無新 SR/MA 或 Cochrane 回顧。
所有 L5 主流臨床機構(Mayo、Cleveland、Harvard、AAD)皆完全未提及乳鐵蛋白於痘痘的應用,AAD 2024 指南聚焦於 BPO、外用 A 酸、口服 doxycycline 等實證療法。
NIH ODS 無乳鐵蛋白 fact sheet,痘痘亦非其證據圖譜涵蓋項目。
整體屬「有 PubMed 初步正向證據但臨床機構零背書」之新興補充療法定位,僅可作為輔助而非一線治療。

A systematic review of lactoferrin use in dermatology
結論:Narrative review of 6 clinical studies concluded there is 'encouraging' evidence that lactoferrin may benefit acne, psoriasis and diabetic ulcerations but explicitly stated further research is necessary before it can be a complementary therapy; no meta-analytic pooling or effect size was performed.
前往 PubMed A randomized, double-blind, placebo-controlled trial to determine the efficacy and safety of lactoferrin with vitamin E and zinc as an oral therapy for mild to moderate acne vulgaris
結論:Combination lactoferrin+vitamin E+zinc cut total lesions vs placebo by 28.5% at week 10 (p<0.0001), with inflammatory lesions down 44% and comedones down 32.5% (both p<0.0001) and no adverse events, BUT the benefit cannot be attributed to lactoferrin alone (3-ingredient combination) and the trial was run by the manufacturer's own R&D division.
前往 PubMed Dietary effect of lactoferrin-enriched fermented milk on skin surface lipid and clinical improvement of acne vulgaris
結論:At 12 weeks the 200 mg/day lactoferrin fermented-milk group showed reductions vs placebo in inflammatory lesions (38.6%), total lesions (23.1%), acne grade (20.3%) and sebum (31.1%) with a selective fall in skin-surface triacylglycerols, but the small trial (n=36) labels these 'significant' without reporting any p-values or CIs and leans heavily on the surrogate lipid endpoint.
前往 PubMed Efficacy and tolerability of oral lactoferrin supplementation in mild to moderate acne vulgaris: an exploratory study
結論:In this UNCONTROLLED open-label study (39 completers) total lesions fell 22.5% (p<0.001) and non-inflammatory lesions 23.5% (p<0.001) from baseline, but inflammatory lesions changed only 20.2% and non-significantly (p=0.054); with no control arm these within-subject changes cannot be separated from natural fluctuation/regression to the mean.

📍立場總覽
台灣社群(PTT、Dcard、Mobile01)幾乎沒有以「乳鐵蛋白抗痘」為主題的個人實測心得;多數討論是「乳清蛋白爆痘」並與乳鐵蛋白混淆。少數媽寶板與保健文章提到乳鐵蛋白安全性高,但對痘痘的療效屬於資料不足。
💬社群實感
資料不足
破解迷思 社群最常見的 4 個誤解
✓
事實把乳鐵蛋白與乳清蛋白搞混,認為兩者都會爆痘
✓
事實誤以為乳鐵蛋白主要功能是抗痘,其實社群多用於提升免疫、嬰幼兒保健
✓
事實認為「天然奶製品成分」就一定不會刺激痘痘
✓
事實以為高劑量乳鐵蛋白可以替代外用痘痘藥膏
🩹 社群通報的副作用
- 高劑量可能腹痛、腹瀉
- 乳製品過敏者需注意
- 與乳清蛋白併服時部分人回報冒痘(多歸因於乳清而非乳鐵)
