Olive oil can be good for your skin, but with some important caveats. It works well as a moisturizer for dry, rough patches on the body, and its natural antioxidants offer real protective benefits. But its high oleic acid content can disrupt the skin barrier in some people, particularly those with sensitive or acne-prone skin. Whether olive oil helps or hurts depends on your skin type, where you apply it, and how you use it.
Why Olive Oil Works as a Moisturizer
Olive oil is rich in oleic acid, a fatty acid that penetrates the outer layer of skin and helps lock in moisture. It also contains squalene, a natural compound found in human skin that acts as an emollient. Virgin olive oils contain between 0.8 and 13 grams of squalene per kilogram, depending on the variety and how the oil was processed. Squalene absorbs quickly and deeply into the skin without leaving a greasy residue, helping restore suppleness and flexibility.
The antioxidants in olive oil, including vitamin E and polyphenols, help reduce oxidative stress on the skin. This is one reason olive oil has been used for centuries in skin care across Mediterranean cultures. These compounds work against the kind of cellular damage caused by sun exposure and environmental pollution, which contribute to premature aging.
Benefits for Dry and Inflamed Skin
Clinical trials and observational studies have found that topical olive oil can reduce the severity of skin lesions, itching, and scaling in people with inflammatory skin conditions. In atopic dermatitis (eczema), olive oil’s fatty acids help maintain the skin’s moisture barrier, while a compound called oleuropein appears to dial down the inflammatory signals that drive flare-ups. Research shows oleuropein inhibits the expression of several key inflammatory proteins involved in the immune overreaction that characterizes eczema.
There’s also evidence supporting olive oil for wound healing. A randomized controlled trial in patients with diabetic foot ulcers found that topical olive oil dressings improved healing of mild-to-moderate wounds. The proposed mechanisms include improved blood flow to the tissue and reduced inflammation at the wound site.
The Skin Barrier Problem
Here’s where olive oil gets complicated. The same oleic acid that helps it penetrate and moisturize can also weaken your skin’s protective barrier. A controlled study involving 19 adults found that topical olive oil significantly increased the skin’s permeability and water loss. Another randomized trial observed that olive oil reduced the integrity and thickness of the outermost skin layer and caused mild redness.
This matters because your skin barrier is what keeps irritants, allergens, and bacteria out while holding moisture in. If you already have a compromised barrier, as many people with eczema or rosacea do, olive oil could make things worse rather than better. The research on olive oil and eczema is genuinely mixed: some studies show it helps modulate inflammation, while others show it damages the very barrier that eczema patients need to protect.
If your skin is generally healthy and you’re using olive oil on rough, dry areas like elbows, knees, or cracked heels, the risk of barrier disruption is low. On delicate facial skin or skin that’s already irritated, you’re more likely to run into problems.
Olive Oil and Acne-Prone Skin
Olive oil scores between 2 and 3 on the comedogenic scale, which runs from 0 (won’t clog pores) to 5 (highly likely to clog pores). That puts it in the moderately comedogenic range. For people who are already prone to breakouts, applying olive oil to the face can trigger or worsen acne by clogging pores and trapping bacteria.
If you have oily or combination skin, olive oil on your face is generally not a good idea. On the body, where skin is thicker and pores are less prone to clogging, the risk is much lower.
Should You Use It on Baby Skin?
A pilot trial of 115 healthy newborns tested olive oil, sunflower oil, and no oil for daily skin care over four weeks. Both oil groups showed improved skin hydration, but they also showed significantly less improvement in the structure of the skin’s lipid layers compared to the no-oil group. There were no differences in water loss, pH, or redness between the groups. The researchers concluded that caution is warranted when recommending oils for newborn skin, as the developing skin barrier in infants may be more vulnerable to disruption.
How to Use Olive Oil on Your Skin
If you want to try olive oil topically, start with dry, rough patches rather than applying it all over. Cracked heels, dry elbows, and flaky shins are good places to begin. Choose extra virgin olive oil when possible, as it retains more of the antioxidants and squalene that are lost during refining.
Apply it to damp skin, ideally right after a shower. Your pores absorb more of the oil when skin is still moist. Use a small amount. A few drops go a long way, and letting it sit for a few minutes before getting dressed gives it time to absorb. It’s safe to leave olive oil on overnight.
If you notice any redness, itching, or new breakouts after a few days of use, your skin likely doesn’t tolerate it well. People with sensitive, acne-prone, or eczema-affected skin on the face should be especially cautious, or skip olive oil on those areas altogether in favor of products specifically formulated for compromised skin barriers.
