未精练的 Jojoba Oil 呈金黄色液体,而精练后则无色无味,与一般植物油相比,其安定性高,OSI(Oxidative Stability Index) 值约为 60,较 Safflower oil、Canola oil、Almond oil、Squalene 稳定,但不如 Castor oil、Macadamia oil 及 Coconut oil,广泛被应用于各种化妆品、个人护理用品中,尤其是皮肤于头髮的部份[1]。
全方位精华保养成分,与鲸油、鲸蜡特性相近,但却不似后者有保育问题。保溼性极佳,涂抹后会在肌肤形成保护层,并稳定肌肤表面油脂,其所含维生素E能保护肌肤结缔组织,减少细纹产生。对于油性肌肤使用者,建议减少用量并搭配其他植物油使用[2]。

Jojoba oil在网上很多说明里都认为是一种不致粉刺、无刺激,适合痘皮、油皮的成分。不知道这里面的致粉刺性是否确切,依据是什么?或者是它的某些种类有致粉刺性,比如精炼加工的霍霍巴油?
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.
