What is phenoxyethanol in skincare?
Phenoxyethanol is a glycol ether used as a broad-spectrum preservative. It occurs naturally in green tea and chicory, though the cosmetic grade is synthesised for purity.
Its job is unglamorous but essential: any product containing water will grow bacteria, yeast and mould without one. Phenoxyethanol became the default after parabens fell out of consumer favour, and it now appears in a large share of skincare on the market, capped at 1% in most jurisdictions.
What skin concerns does phenoxyethanol treat?
None – it is not an active. It protects the product rather than the skin, and in doing so protects you from applying a contaminated formula to your face, which is a real infection and irritation risk.
Its safety has been examined repeatedly. A safety review of phenoxyethanol as a cosmetic preservative and the EU Scientific Committee on Consumer Safety opinion both conclude it is safe at the permitted concentration. Allergic contact dermatitis happens but is uncommon.
What ingredients are best paired with phenoxyethanol?
It is usually combined with ethylhexylglycerin, caprylyl glycol or organic acids, which boost its activity and let formulators use less of it.
You do not choose products for their preservative, but it is worth knowing that unpreserved or self-preserving formulas are not automatically safer – they spoil faster and carry their own risk. If you react to it, patch testing with a dermatologist will confirm it before you rule out half the market. Take our Skin Quiz.
What is oily skin?
Oily skin is a skin type in which the sebaceous glands produce more sebum than the skin needs. It shows up as shine through the T-zone within hours of cleansing, visibly enlarged pores, makeup that slides or separates, and a tendency towards blackheads and congestion.
Sebum itself is not the enemy – it carries vitamin E to the surface, keeps the barrier supple and helps oily skin hold its structure, which is why it often shows fine lines later than dry skin does.
What causes oily skin?
Genetics and androgen activity are the primary drivers of how much sebum your glands produce. Heat and humidity increase output measurably, and hormonal fluctuations across the monthly cycle, pregnancy or puberty shift it again.
Stress, a diet heavy in refined carbohydrates, and – counter-intuitively – over-cleansing with stripping foams or alcohol-based toners all push oil production up, because skin compensates for a damaged barrier by making more.
What ingredients are best for oily skin?
Look for salicylic acid (a BHA that is oil-soluble, so it clears inside the pore), niacinamide and zinc to regulate sebum, clay such as bentonite or kaolin for weekly absorption, and retinoids or azelaic acid to normalise how pores shed.
Do not skip hydration: lightweight humectants like hyaluronic acid and glycerin, plus non-comedogenic squalane or jojoba oil, keep the barrier intact so the skin stops over-compensating. Skip heavy occlusive balms and high-alcohol toners. Take our Skin Quiz to get the balance right for your skin.
