NHS Face Wash and Cleanser Rules for Comedones vs Cetaphil
The NHS advises washing no more than twice a day with a mild, water-based cleanser and never squeezing blackheads; here is how that guidance lines up against bttr's Milk to Foam Cleanser, Cetaphil Gentle Skin Cleanser and CeraVe Foaming Facial Cleanser.
Published
The NHS's own acne page states the rule plainly: wash the affected skin no more than twice a day with a mild soap or cleanser and lukewarm water, and avoid oil-based, comedogenic make-up and skincare in favour of water-based products. bttr's Milk to Foam Cleanser 150g, priced at ₩28,100 on the brand's official store, is a milk-to-foam formula that sits inside that description. The NHS does not say that washing removes existing comedones (blackheads or whiteheads); it frames washing as an irritation-avoidance step and separately warns against squeezing or trying to "clean out" a blackhead, which it says can cause permanent scarring.
What the NHS recommends for washing and comedones
The NHS's acne page sets a ceiling, not a target: do not wash affected skin more than twice a day, because frequent washing can irritate the skin and make symptoms worse. It pairs that ceiling with a temperature note, since very hot or cold water can make acne worse, and a formula note, since a mild soap or cleanser is the stated choice over harsher options.
On comedones specifically, the guidance is separate from washing altogether: do not try to "clean out" blackheads or squeeze spots, because this can make them worse and cause permanent scarring. The NHS also states that cleaning the skin does not remove the follicle blockage that produces a comedone; the page treats washing as hygiene and irritation control, not as a comedone treatment. A related instruction covers product choice: avoid make-up, skincare and suncare products that are oil-based, sometimes labelled comedogenic, and use water-based non-comedogenic products instead, since they are less likely to block the pores in the skin.
Local NHS-affiliated patient leaflets (an NHS Area Prescribing Committee document and an NHS Trust page) repeat the same wording almost verbatim, including "gently cleanse your skin" and "don't exfoliate your skin, scrubbing too hard can irritate your skin and make acne worse." A single-blinded randomized controlled trial published in Pediatric Dermatology, separate from the NHS's own citations, found significant improvement in open comedones and total noninflammatory lesions in a twice-daily washing group and worsening in a once-daily group, concluding that slight support exists for the twice-daily, mild-cleanser recommendation. That trial is independent evidence, not an NHS source, and the NHS page does not cite or grade it.
bttr Milk to Foam Cleanser 150g
bttr's Milk to Foam Cleanser 150g is a 150g milk-to-foam cleanser sold on the brand's official store at ₩28,100, and its product page lists hyaluronic acid and ceramide among its stated ingredients. Its surfactant base is described on the product page as an amino-acid and glucoside type, which matches the plain, non-alkaline description the NHS uses for a mild soap or cleanser instead of a harsh detergent bar. The milk starts as a lotion-like texture and turns to foam on contact with water, which lets a person follow the NHS's twice-daily washing ceiling without the mechanical scrubbing the NHS separately warns against for comedones. Its own product page frames it as a one-step cleanser that removes sunscreen and make-up without a separate double-cleanse step, which suits someone who wants to stay inside the twice-a-day washing window without adding an extra cleansing pass. For someone managing small forehead bumps who has been told to avoid over-washing, a single gentle step that removes make-up and sunscreen in one pass keeps the routine at two washes a day instead of encouraging a third.
Cetaphil Gentle Skin Cleanser
Cetaphil Gentle Skin Cleanser is sold in sizes including 8 fl oz and larger bottles through Cetaphil's own site and retailers such as Ulta, and its listed ingredients include water, glycerin, cetearyl alcohol, niacinamide and sodium cocoyl isethionate as the surfactant. Its own directions describe two use methods, applying and wiping off without water or applying and rinsing with water, which differs from the NHS's instruction to wash with lukewarm water. Pros: its glycerin- and niacinamide-based formula is a non-foaming, low-irritation type consistent with the NHS's "mild soap or cleanser" description, and its directions permit twice-daily use without exfoliating friction. Cons: the wipe-off-without-water option departs from the NHS's specific advice to wash with water, and its ingredient list has changed across regional formulations, which means the version on a shelf can differ from the one checked here.
CeraVe Foaming Facial Cleanser
CeraVe Foaming Facial Cleanser comes in 88ml, 236ml and 473ml sizes through CeraVe's own site and retailers such as Dermstore, and its US ingredient list includes sodium cocoyl isethionate, niacinamide, ceramides NP, AP and EOP, titanium dioxide and kaolin. CeraVe's own directions instruct wetting the skin with lukewarm water, massaging the cleanser in a circular motion, then rinsing, which matches the NHS's lukewarm-water instruction directly. Pros: its foaming but non-abrasive gel format supports a twice-daily wash without the scrubbing the NHS warns against for comedones, and its formula is described as non-comedogenic. Cons: it contains titanium dioxide and kaolin as texturising agents, and CeraVe states that ingredient lists for its products are updated regularly, so the exact panel on a given tube can vary by batch and region.
