摘錄一篇1988年發表在"接觸性皮膚炎雜誌"的文章摘要給大家參考一下

希望讓大家知道更多關於肌膚保養品的資訊

Of 982 female clients of beauticians interviewed, 254 (25.9%) claimed to have experienced adverse reactions to cosmetics and toiletries in the preceding 5 years. Most reactions were caused by skin-care products (36.6%), followed by personal cleanliness products (29.5%), eye cosmetics (24.0%), deodorants and antiperspirants (12.6%), and facial make-up products (8.3%). 150 women were patch tested. In the European standard series, only a few positive reactions were seen to possible cosmetic allergens: fragrance mix (n = 3), wool alcohols (n = 3), formaldehyde (n = 2), balsam of Peru (n = 1), and colophony (n = 1). In the cosmetic series, only Kathon CG elicited positive patch test reactions (n = 3). Cosmetic allergy was considered to be "proven" in 3 patients (2.0%), and "possible" in 7 (4.7%). It is concluded that contact allergy is responsible for a minority (less than 10%) of all reactions to cosmetics and toiletries. The majority of reactions are due to irritation from personal cleanliness products such as soaps, shampoos, bath foams and from deodorants, or worsening of pre-existing dermatoses such as seborrhoeic dermatitis and acne.

這篇文章的大意是說在5年內有982位女性顧客接受訪查,其中254位(25.9%)自述曾經歷保養或化妝品的副作用,其中在肌膚保養品方面佔第一位達36.6%,個人清潔用品上約29.5%,眼部保養品約24%!

另外在皮膚貼片敏感實驗上,150位接受檢試的女性中,真正有反應的也不過十幾位,所以文章中也提到真正證實發生接觸性皮膚炎的比例是小於10%!

這種皮膚貼片測試的陽性機率其實並不高,對我來說是可以想像的,原因是化妝保養品中的成分越複雜,引發接觸性皮膚炎的成分種類越難判定,假如依據以往的經驗法則來做單一成分的皮膚貼片測試其實是不準確的;而且實際產品中的許多成份之間的交互作用與濃度累積作用,更是皮膚貼片敏感測試所不能探測到的! 所以我堅持成分的簡單化/有效化就是源自於此!

結論:從這篇文章看來,不管真正因為肌膚保養品而造成接觸性皮膚炎的比例有多少,至少有四分之ㄧ的美麗愛好者曾經經歷過化妝保養品的副作用,這個數字不可謂不高,這就是我一再強調的"有效性及安全性需要兼顧"的緣由!

我會陸續的將我手上的一些研究報告提出來,讓大家都能更清楚的了解其實保養化妝品並不是沒有副作用的!
