Acne-prone skin tends to have linoleic acid and high levels of oleic acid.
Linoleic acid can also help treat acne by softening sebum to prevent clogged pores. Another study found using 2.5% linoleic acid gel for 4 weeks showed a 25% reduction in small comedones.
This ingredient can also help lighten hyperpigmentation or sun spots by disrupting the melanin production process. It also helps your skin shed melanin pigment from your skin caused by UV exposure.

Nice feel, but not for sensitive skin
You cant go wrong with the price point of this moisturizer. I have the self-proclaimed most sensitive skin on the planet and found that this left a burning sensation for minutes after application. tried a few times before giving up but still burning continued.
