Washing Your Face With Olive Oil — What the Science Says and Who It Actually Works For

Oil cleansing has been practised for centuries — ancient Egyptians, Greeks, and Romans all used oils to cleanse skin before modern soap existed. The method fell out of favour with the rise of the detergent-based cleansing industry and has recently experienced a significant revival driven by the clean beauty movement and anecdotal reports of dramatic skin improvements.

The central claim is that oil dissolves oil — that applying a plant-based oil to the face breaks down sebum, sunscreen, and makeup more effectively than conventional cleansers while preserving the skin barrier that harsh detergents strip. The counter-argument is that applying oil to skin clogs pores and causes breakouts.

Both positions contain truth. The reality is more nuanced — and depends significantly on skin type, the specific oil used, and the method of application.

The Chemistry — Why Oil Cleansing Makes Sense

The like-dissolves-like principle is legitimate chemistry. Sebum — the skin’s natural oil — is a lipid. Makeup, sunscreen, and environmental pollutants that accumulate on skin throughout the day are largely lipid-based. Oil-based cleansers dissolve these substances more effectively than water-based cleansers because they share the same chemical polarity.

Conventional detergent cleansers — including many foaming and gel cleansers — use surfactants that strip not just sebum and impurities but the skin’s natural lipid barrier. The skin barrier is a carefully balanced structure of ceramides, fatty acids, and cholesterol that maintains hydration and protects against environmental damage and microbial invasion.

Repeated stripping of this barrier — which many people do twice daily with harsh cleansers — produces a well-documented cycle. The skin responds to barrier disruption by producing more sebum to compensate, which leads to the perception of oily skin that drives the use of more stripping cleansers. The oil cleansing method breaks this cycle by dissolving impurities without disrupting the lipid barrier.

This mechanism is well-supported by dermatological research on skin barrier function. The question is whether olive oil specifically is the right vehicle for it.

What Olive Oil Actually Does to Skin

Olive oil is rich in oleic acid — a monounsaturated fatty acid that makes up approximately 70 to 80 percent of its composition. Oleic acid has well-documented skin-softening and emollient properties and penetrates the skin effectively.

However oleic acid has a significant limitation for facial skin use — it is mildly disruptive to the skin barrier in some individuals. Research published in the British Journal of Dermatology found that topical olive oil application impaired skin barrier function and increased transepidermal water loss compared to sunflower oil — which is predominantly linoleic acid rather than oleic acid.

The distinction between oleic acid and linoleic acid dominant oils is one of the most important and least discussed factors in oil cleansing. Linoleic acid — found in high concentrations in rosehip oil, hemp seed oil, and sunflower oil — reinforces the skin barrier rather than disrupting it and is better tolerated by acne-prone and sensitive skin.

Olive oil’s high oleic acid content means it performs differently on different skin types. For dry, mature, or non-acne-prone skin it provides excellent cleansing with good emollient benefit. For oily, acne-prone, or sensitive skin it is more likely to cause congestion and irritation than linoleic acid dominant alternatives.

The Comedogenicity Question

Olive oil has a comedogenicity rating of 2 on a scale of 0 to 5 — meaning it has low to moderate pore-clogging potential. This is not the highest rating on the scale — coconut oil sits at 4 — but it is not negligible for people prone to congestion.

Comedogenicity ratings are based on rabbit ear models — a testing method with limited direct applicability to human facial skin. Individual variation is significant. Some people with acne-prone skin use olive oil without issue. Others experience significant breakouts.

The pattern that tends to emerge from clinical observation is that olive oil cleansing works well for dry and mature skin types and poorly for oily and acne-prone skin — with normal and combination skin falling somewhere between depending on individual sebum composition.

How to Do It Correctly

For people whose skin type is compatible with olive oil cleansing, method matters significantly. Incorrect application produces most of the negative outcomes reported.

Use the right grade: Extra virgin olive oil — cold pressed, minimally processed — contains higher concentrations of antioxidants and anti-inflammatory compounds than refined olive oil. The polyphenol content of extra virgin olive oil has documented anti-inflammatory and antimicrobial properties relevant to skin health.

Apply to dry skin: Apply a small amount — approximately a teaspoon — to dry skin. Massage gently in circular motions for 60 to 90 seconds. The massage component is important — it emulsifies the oil with sebum and loosens debris from pores. Do not apply to wet skin as this dilutes the oil and reduces its solvent effectiveness.

Steam removal: Wet a soft cloth with warm water and hold against the face for 30 seconds before wiping gently. The steam opens pores and the cloth removes the oil along with dissolved impurities. Rinse thoroughly with warm water. This step is critical — oil left on the skin after cleansing is the primary cause of congestion and breakouts associated with the method.

Follow with a light moisturiser: For most skin types a light water-based moisturiser applied to slightly damp skin after oil cleansing maintains hydration without adding additional oil to the skin surface.

Who It Works For

Dry skin: Olive oil cleansing is well-suited to dry skin — it dissolves impurities without stripping moisture and the oleic acid provides emollient benefit that dry skin lacks.

Mature skin: Older skin typically produces less sebum and has a compromised lipid barrier. Oil cleansing restores barrier lipids while cleansing effectively — producing the improved hydration and reduced tightness that many mature skin users report.

Skin sensitive to conventional cleansers: People who experience stinging, tightness, or increased sensitivity from foaming and gel cleansers often do well with oil cleansing — the absence of surfactants eliminates the primary irritant.

Makeup wearers: Oil cleansing is particularly effective for dissolving heavy or long-wear makeup — it breaks down silicones, pigments, and waterproof formulas that water-based cleansers struggle with.

Who Should Use a Different Oil

Acne-prone skin: The combination of oleic acid dominance and moderate comedogenicity makes olive oil a poor choice for acne-prone skin. Rosehip oil, hemp seed oil, or jojoba oil — which mimics the skin’s own sebum composition — are better alternatives with lower comedogenic ratings and higher linoleic acid content.

Oily skin: Olive oil may exacerbate congestion in oily skin types. Jojoba oil is generally the most well-tolerated option for oily skin — it is technically a wax ester rather than a triglyceride oil and has a comedogenicity rating of 0 to 2.

Rosacea-prone skin: The oleic acid in olive oil can trigger inflammatory responses in some rosacea-prone individuals. Patch testing on a small area before committing to full facial use is essential.

The Double Cleanse Alternative

For people interested in oil cleansing benefits without committing to olive oil as a standalone cleanser, the double cleanse method offers a middle ground. An oil-based cleanser or balm cleanser is used first to dissolve oil-based impurities — makeup, sunscreen, sebum — followed by a gentle water-based cleanser to remove any remaining residue and water-soluble impurities.

This method is extensively used in Korean skincare — where it originated — and has good evidence for thorough cleansing without barrier disruption. Dedicated oil cleansers formulated for facial use are designed to emulsify with water and rinse cleanly — reducing the residue risk that makes DIY olive oil cleansing problematic for some skin types.

The Bottom Line

You can wash your face with olive oil — and for the right skin type, applied correctly, it works well. The like-dissolves-like chemistry is legitimate, the barrier-preservation argument has merit, and the anecdotal reports of improved skin texture and hydration from dry and mature skin users are consistent with what the science would predict.

But olive oil is not universally suitable. Its oleic acid dominance and moderate comedogenicity make it a poor choice for oily, acne-prone, and congestion-prone skin. For these skin types linoleic acid dominant oils or dedicated oil cleansers provide the benefits of oil cleansing without the drawbacks.

The method matters as much as the product. Correct application — dry skin, adequate massage time, thorough steam removal — determines outcomes more than the specific oil chosen.
