Avocado Carrier oil can penetrate into the second layer of the skin (dermis) and provide deep moisturizing with its oleic acid and phytosterols. People who have a dry and sensitive skin type are usually advised to use oils rich in oleic acid. The lecithin in avocado oil helps boost collagen, and the pro-vitamin A carotenoids lutein and zeaxanthin enhance the skin’s natural antioxidant store.
