1. Moisturizes and nourishes
In addition to vitamin E, avocado oil contains potassium, lecithin, and many other nutrients that can nourish and moisturize the skin.
The outermost layer of skin, known as the epidermis, easily absorbs these nutrients, which also help to form new skin.
2. Relieves inflammation from psoriasis and eczema
A person with a skin condition may wish to test a patch of skin first, to ensure that the oil does not trigger or aggravate their symptoms.
3. Prevents and treats acne
When left on for short periods of time and rinsed off with warm water, avocado oil can keep skin hydrated without leaving an oily residue. This may reduce the risk of acne.
4. Accelerates wound healing
Avocado oil may help wounds to heal more quickly. One 2013 study found that the essential fatty acids and oleic acid in avocado oil can promote collagen synthesis, which is the process of creating new connective tissue.
The essential fatty acids in avocado oil were also found to help reduce inflammation during the healing process.
More studies are needed in humans, however, to determine whether avocado oil can be used to treat wounds.
5. Treats sunburned skin
The antioxidants in avocado oil may help to ease the symptoms of a sunburn. According to a 2011 review, the vitamin E, beta carotene, vitamin D, protein, lecithin, and essential fatty acids in the oil can support healing and soothe the skin.
Other small studies have shown that consuming avocados may help to protect the skin from harmful UV radiation.
6. Reduces signs of aging
The first signs of aging usually appear on the skin. Some studies have shown that consuming healthful fats, such as those found in avocados, can help the skin to retain its elasticity.
However, researchers have yet to address whether applying avocado oil to the skin has the same effect.
7. Improves nail health
While some people use avocado oil to heal dry, brittle nails, little scientific evidence confirms this benefit.
However, using natural oils to keep the nails and surrounding skin soft may help to reduce breakage.
8. Improves scalp health
Applying avocado oil to the scalp as a hot oil mask can help to reduce dandruff and other problems caused by a dry, flaky scalp.
