Today there are abundant options for a pure mineral sunscreen. However, common complaints about non-nano mineral sunscreens is that they’re oily, sticky and thick and leave a white cast. Claims about the SPF of natural oils are still not scientifically substantiated. However, there is evidence that natural oils provide some skin protection. According to a study in 2016, “Avocado oil is SPF 15 and contains high levels of healthy monounsaturated fats, phytosterols and antioxidants like vitamin-E.” Olive oil has an SPF of 7.549, slightly higher than coconut oil at 7.119 according to a 2010 study. Also, avocado and olive oils are abundant in antioxidants, tocopherols, β-carotene, lutein, squalene and lipophilic and hydrophilic phenols to stop free radical damage when zinc oxide is exposed to UV.
