Prickly Pear Seed Oil

Prickly pear seed oil is among the most expensive plant oils in cosmetics, and the reason is arithmetic. It takes roughly a tonne of cactus fruit to produce a single litre of oil. The seeds are tiny, the oil content is low, and the extraction is slow.

What you get for that is one of the highest linoleic acid concentrations available in a plant oil, generally above 60 percent. This matters because linoleic acid content in skin sebum is measurably lower in people with acne-prone skin. Oils high in linoleic acid tend to sit comfortably on skin types that react badly to heavier, oleic-dominant oils.

It also carries a notably high level of vitamin E and of sterols, both of which contribute antioxidant and barrier-supporting activity.

In practice it feels much lighter than its richness suggests. It absorbs quickly and does not leave the residue people expect from a facial oil, which is why it works in both the serum and the face cream.

If you have tried facial oils before and found them greasy or congesting, there is a good chance the oil in question was oleic-dominant. Linoleic-rich oils behave differently, and prickly pear is the clearest example of that difference.
