Intimate Wash and pH: What ‘pH-Balanced’ Really Means

“pH-balanced” on an intimate wash sounds reassuring, but your vagina doesn’t need a special product to stay balanced. A healthy vagina is naturally acidic, with a pH of about 3.8 to 4.5. NHS guidance is to wash the skin around the vagina (the vulva) once a day with warm water, and if you like, a mild unperfumed soap, and never to wash inside the vagina. Perfumed products, scented wipes and douching are the things most likely to upset that balance.

What vaginal pH means

pH measures how acidic something is: the lower the number, the more acidic. According to Cleveland Clinic, a typical vaginal pH is between 3.8 and 4.5.

Several everyday things can raise pH (make it less acidic) for a while:

• semen, condoms and lubricants;
• douching, or hygiene products with irritating chemicals or fragrance;
• antibiotics, which kill helpful as well as harmful bacteria;
• hormonal changes, for example just before a period and after menopause.

A raised pH is linked with infections such as bacterial vaginosis and trichomoniasis.

Plain water, soap or an intimate wash?

None of these sources recommends a special “pH-balanced” wash. If you choose one, pick an unperfumed product, use it only on the outside, and stop if it stings or itches. If you have bacterial vaginosis, or it keeps coming back, NHS advice is different: do not use vaginal washes, deodorants or douches, and wash the genital area with water and plain soap.

If your skin is sensitive

An NHS vulval-care leaflet advises:

• cleaning the vulva once a day, without over-washing, which can make symptoms worse;
• a soap substitute (emollient) if soap feels drying;
• patting dry with a soft towel;
• loose cotton or silk underwear, and avoiding fragranced washing powders and fabric conditioners;
• not using panty liners every day.

Home pH tests

Kits with colour-changing paper can show whether your vaginal pH is raised. According to Cleveland Clinic, they can’t tell you why it’s raised or which infection you might have, so they don’t replace a check-up.

When to see a doctor

See a GP or sexual health clinic if your discharge changes colour, smell or texture, or if you have itching, soreness, unusual bleeding or pelvic pain. The NHS lists some typical patterns:

• a fishy smell can point to bacterial vaginosis;
• thick, white, cottage-cheese-like discharge to thrush;
• green, yellow or frothy discharge to trichomoniasis.

Don’t try to wash a smell away. Extra washing or douching can make things worse, and the cause may need treatment. For comfort during sex if you have dryness, see our water-based lubricants.

The takeaway

For most people, warm water is enough to keep the vulva clean; a “pH-balanced” wash is optional, not necessary. If you use one, choose a mild, unperfumed product and use it on the outside only. If you have bacterial vaginosis, the NHS advises against vaginal washes altogether. See a doctor about any change in discharge, smell, itching or soreness rather than trying another wash.
