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 are clogged pores?
A clogged pore is a hair follicle blocked by a mix of sebum, dead skin cells and debris. Left open to the air the plug oxidises and darkens into a blackhead; sealed over by skin it becomes a whitehead or closed comedone.
Clogged pores are the starting point of nearly all acne – the microcomedone forms first, and inflammation follows only if bacteria and immune response get involved.
What causes clogged pores?
Excess sebum and abnormal keratinisation are the two mechanics. When the follicle lining sheds cells faster than they can clear, they bind with oil and form a plug.
Comedogenic products (heavy oils, some silicones and waxes), thick makeup worn for long stretches, humidity, sweat left on the skin, hormonal shifts and insufficient cleansing all contribute. So does over-cleansing, which damages the barrier and drives oil production up.
What ingredients are best for clogged pores?
Salicylic acid is the first choice because it is oil-soluble and works inside the pore rather than just on the surface. Glycolic and lactic acid clear the surface layer, and clay masks absorb excess oil weekly.
Retinoids are the most effective long-term fix, because they change how the follicle sheds in the first place. Add niacinamide to regulate sebum and keep the barrier intact, and switch to non-comedogenic, lightweight hydrators. Take our Skin Quiz to find products that will not re-clog you.
