Avocado oil is pressed from the fruit's flesh rather than a seed, which is unusual among common carrier oils, and is rich in oleic acid along with an unusually high fraction of unsaponifiable compounds, particularly the plant sterol beta sitosterol.
Beyond ordinary emollient action, this sterol rich fraction has been linked in animal wound healing studies to increased collagen deposition and a calmer inflammatory response during healing, consistent with sterols' known role in modulating fibroblast activity.
Because that supporting research comes from rat models rather than human trials, claims that avocado oil accelerates healing or boosts collagen in human skin extend beyond what has actually been demonstrated in people.

Our team reviews ingredient research and uses up-to-date evidence to rate ingredients based on the categories below.
Best
Ingredients with the most rigorous and convincing evidence. These are the standouts backed by consistent findings across independent, peer reviewed clinical research.. When we call an ingredient Best, it has earned that distinction through genuine, reproducible proof that it improves skin.
Good
Reliable, well tolerated ingredients that do their job without complaint. They may not carry the headline benefits of a Best rated active, but they hydrate, stabilize a formula, or support the ingredients around them in ways that make a real difference in how a product performs and feels.
Average
Ingredients that are perfectly safe and serve a clear function, typically as an emollient, thickener, or filler, but do not offer any meaningful skin benefit beyond that basic job. Not a red flag, just not a reason to choose one product over another.
Bad/Worst
Ingredients with documented potential to irritate skin, disrupt the barrier, or trigger sensitization in some users, often synthetic fragrance, drying forms of alcohol, or certain essential oils. Not automatically a dealbreaker for every skin type, but worth knowing about before you commit to a product.
