Avocado oil is used to support or treat wrinkles primarily based on some scientific evidence, though the strength of this evidence is modest. Avocado oil is rich in unsaturated fatty acids, vitamin E, and other antioxidants, which are known to have beneficial effects on skin health. Laboratory studies have shown that these components can help protect skin cells from oxidative stress, a key factor in the aging process and the formation of wrinkles. For example, in vitro studies suggest that the oil can stimulate collagen synthesis and reduce inflammation, both of which are relevant to maintaining skin elasticity and reducing the appearance of wrinkles (PMID: 22517537). However, clinical studies specifically evaluating the effect of topical avocado oil on wrinkles in humans are limited. Most of the available evidence comes from small studies or indirect evidence, such as improvements in skin barrier function and hydration, which are associated with healthier, more youthful-looking skin. There is also some support from studies on blends of avocado oil with other oils or active ingredients, though it is unclear how much of the benefit is attributable to avocado oil alone. In summary, while theoretical and experimental support exists for the use of avocado oil in addressing wrinkles, high-quality human studies are lacking, making the overall evidence moderate but not robust.
