未精練的 Jojoba Oil 呈金黃色液體,而精練後則無色無味,與一般植物油相比,其安定性高,OSI(Oxidative Stability Index) 值約為 60,較 Safflower oil、Canola oil、Almond oil、Squalene 穩定,但不如 Castor oil、Macadamia oil 及 Coconut oil,廣泛被應用於各種化妝品、個人護理用品中,尤其是皮膚於頭髮的部份[1]。
全方位精華保養成分,與鯨油、鯨蠟特性相近,但卻不似後者有保育問題。保溼性極佳,塗抹後會在肌膚形成保護層,並穩定肌膚表面油脂,其所含維生素E能保護肌膚結締組織,減少細紋產生。對於油性肌膚使用者,建議減少用量並搭配其他植物油使用[2]。

Jojoba oil在網上很多說明裏都認為是一種不致粉刺、無刺激,適合痘皮、油皮的成分。不知道這裏面的致粉刺性是否確切,依據是什麼?或者是它的某些種類有致粉刺性,比如精煉加工的霍霍巴油?
純天然的荷荷巴油如果沒有其他雜質不應該對皮膚有刺激性,致粉刺的幾率也很小,痘皮,敏皮,都適用,根據wikipedia荷荷巴油也可以抗黴菌
Jojoba oil is my nemesis. I used to have normal, non-sensitive skin. But after trying lotions and serums that contained jojoba oil, I had the WORST breakouts in my life. Cystic pimples and milia, all over my cheeks, around my mouth and forehead. It took a while to figure out that what caused my breakout was jojoba oil, but I had to make couple trips to dermatologists to get rid of horrible breakouts, and it took me months to get rid of acne scars. It turned my skin into acne-prone, sensitive. I used to wear any products without any problems but now I've got sensitive skin, I have to choose makeups/skincare very carefully.
Can be comedogenic for some, but is overall an effective, soothing ingredient.
