Olea Europaea Fruit Oil.

What it does

In cosmetics it is a rich emollient and antioxidant-bearing moisturizer best suited to dry skin.

Benefits

• Rich emollient that moisturizes and nourishes dry skin
• Supplies skin-friendly extras like squalene, vitamin E, and antioxidant polyphenols

Side effects

• Because it is so high in oleic acid, it is heavy and can be poorly tolerated by acne-prone or barrier-impaired skin (INCIDecoder rates it great for dry skin but less so for acne-prone or damaged skin)
• Oleic-rich oils can act as penetration enhancers that disrupt the stratum corneum, so olive oil may aggravate sensitive or compromised barriers for some people
• Its oleic/palmitic acids sit in the C11-C24 range that lipid-dependent Malassezia yeast can feed on, so it is generally flagged as a potential fungal-acne (Malassezia folliculitis) trigger

Who it's for

Dry skin and hair wanting a rich, nourishing oil

Who should be careful

Acne-prone, barrier-impaired/sensitive, or fungal-acne (Malassezia folliculitis)-prone skin should be cautious
