It is also a rich source of mono-unsaturated fatty acids, particularly palmitic, palmitoleic, stearic, oleic, linoleic and linolenic acids. Benefits of avocado oil for the skin As well as its high nutritional value, avocado oil contains some very specific skin benefits. It is high in sterolins, which have been shown to reduce age spots. It is the sterolins (also called plant steroids) in the oil, which also help to soften the skin and impart a wonderful moisturizing effect. For this reason, avocado oil is very effective if you have dry skin, or if your skin is damaged by the sun, as it will help it to regenerate and rejuvenate it. Avocado oil has also been shown to relieve the dryness and itching of skin diseases such as psoriasis and eczema. A study in Israel found avocado oil also significantly increases the amount of collagen in the skin, which normally reduces as we get older.
