From the Guidelines
Olive oil is highly beneficial for skin care due to its rich antioxidant content, anti-inflammatory properties, and ability to hydrate and protect the skin without clogging pores. The oil contains squalene, a natural moisturizer that mimics the skin's own oils, making it excellent for hydration. Olive oil's anti-inflammatory properties can soothe irritated skin and may help with conditions like eczema or psoriasis, as seen in a study where olive oil was compared to indigo naturalis extract in oil for the treatment of nail psoriasis, although it was less effective in this specific case 1. It also contains oleocanthal, which has similar anti-inflammatory effects to ibuprofen, as noted in a comprehensive review of dietary and policy priorities for cardiovascular disease, diabetes, and obesity 1.
Some key benefits of using olive oil on the skin include:
- Hydration and moisturizing properties
- Anti-inflammatory effects to soothe irritated skin
- Antioxidant content to protect against environmental damage and premature aging
- Ability to strengthen the skin barrier due to its similar fatty acid profile to human skin
For best results, use extra virgin olive oil as it's the least processed form with the highest nutrient content. Apply a small amount to damp skin after showering for maximum absorption, or use it as a makeup remover by gently massaging it onto your face before wiping away with a warm cloth. Those with acne-prone skin should use it sparingly as it may be too heavy for some skin types. Additionally, olive oil's potential benefits in reducing the risk of nonalcoholic fatty liver disease have been noted, possibly due to its high content of antioxidant phytochemicals and monounsaturated fats, which can attenuate oxidative stress and improve lipid metabolism 1.
From the Research
Benefits of Olive Oil on the Skin
- The use of olive oil on the skin is a topic of debate, with some studies suggesting it may have negative effects, while others indicate potential benefits when combined with other ingredients 2, 3.
- A study comparing the therapeutic effects of aloe vera and olive oil combination cream versus topical betamethasone for atopic dermatitis found that the combination cream was more effective in reducing disease severity and improving quality of life 3.
- However, another study found that topical application of olive oil for 4 weeks caused a significant reduction in stratum corneum integrity and induced mild erythema in volunteers with and without a history of atopic dermatitis, suggesting that olive oil may not be beneficial for the skin when used alone 2.
- There is no direct evidence in the provided studies to support the use of olive oil as a treatment for acne vulgaris or eczema, with other treatments such as topical retinoids, benzoyl peroxide, and azelaic acid being recommended for acne, and topical corticosteroids and calcineurin inhibitors being recommended for eczema 4, 5, 6.
- Overall, the benefits of using olive oil on the skin are unclear and may depend on the specific condition being treated and the combination of ingredients used.
