What is olive oil in skincare?
Olive oil is pressed from the fruit of Olea europaea and has been used on skin for thousands of years. It is roughly 70% oleic acid, a monounsaturated fatty acid, with smaller amounts of linoleic acid, squalene and polyphenols such as hydroxytyrosol.
That fatty acid profile matters. Oleic-dominant oils are rich and occlusive but, as comparative research on plant oils shows, they can also disrupt the skin barrier rather than repair it – the opposite of what linoleic-rich oils do.
What skin concerns does olive oil treat?
On intact, dry body skin it is an effective emollient and a serviceable makeup remover, and its polyphenols and squalene contribute antioxidant activity.
It is a poor choice for the face if you are acne-prone, since it is comedogenic, and studies have found repeated topical olive oil increases water loss through the barrier rather than reducing it. It is specifically not recommended on infant skin or on eczema.
What ingredients are best paired with olive oil?
If you use it, use it on the body, over hydrated skin, and alongside ceramides and glycerin rather than on its own.
For facial use, linoleic-rich oils – sunflower, grapeseed, rosehip, hemp seed – or non-comedogenic squalane and jojoba do the same job without the barrier penalty. Squalane is in fact derived from olives, and delivers olive oil’s best component without its drawbacks. Take our Skin Quiz.
What is redness?
Facial redness is visible dilation of the small blood vessels near the skin’s surface. It ranges from transient flushing that comes and goes, to persistent erythema across the cheeks and nose, to fixed thread veins that stay visible all the time.
Redness is a symptom rather than a diagnosis. It can signal rosacea, irritation, an over-exfoliated barrier, eczema, an allergic reaction or simply reactive skin that responds strongly to heat and stress.
What causes redness?
Most persistent redness traces back to a compromised barrier and heightened nerve sensitivity. When the barrier thins, irritants penetrate more easily and the skin mounts an inflammatory response to things it would normally tolerate.
Common aggravators: over-exfoliation, high-strength actives used too often, fragrance and essential oils, hot water, alcohol, spicy food, sudden temperature change, sun exposure and stress. Trying to treat redness with more actives usually deepens it.
What ingredients are best for redness?
Prioritise calming and rebuilding over correcting. Niacinamide, azelaic acid, centella asiatica, green tea extract, liquorice root, allantoin, bisabolol and colloidal oatmeal all reduce visible inflammation.
Then repair the barrier with ceramides, cholesterol, fatty acids, glycerin, panthenol and squalane, and protect it with a gentle mineral SPF. Strip the routine back to cleanser, moisturiser and sunscreen for a few weeks before reintroducing anything active. Take our Skin Quiz.
