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 adult acne?
Adult acne is acne that persists past the teenage years or appears for the first time in your twenties, thirties or later. It affects a substantial share of adults, and disproportionately women.
It tends to look different from teenage acne: fewer widespread blackheads, more deep tender lesions along the jawline, chin and neck, often on skin that is simultaneously dry, sensitive or already showing early signs of ageing.
What causes adult acne?
Hormonal fluctuation is the leading driver – menstrual cycles, coming off or starting contraception, pregnancy, perimenopause and conditions such as PCOS all shift androgen activity and sebum output.
Stress and cortisol, sleep debt, high-glycaemic diets, comedogenic makeup and skincare, friction, and certain medications compound it. Adult skin also heals more slowly, so marks linger longer than they did at nineteen.
What ingredients are best for adult acne?
The challenge is treating acne without wrecking a barrier that is also ageing. Retinoids do double duty here, clearing follicles and stimulating collagen at the same time.
Azelaic acid is excellent for adult skin because it handles lesions, redness and post-acne marks together. Add salicylic acid used sparingly, niacinamide to regulate oil and calm inflammation, and ceramides plus hyaluronic acid to keep hydration up. Skip harsh benzoyl peroxide concentrations and scrubs.
