While the vagina is self-cleaning, the same does not apply for the vulva (the outer part of your intimate area), which is not self-cleansing. The vulva produces sweat, that together with urine easily can get trapped in the hair follicles.
The intimate skin can not be treated like the rest of the skin on your body as it has such a delicate ecosystem that can easily be thrown out of balance. Any products used on the vulva should have a pH of 5 (as the vulva has pH 5). You should never wash with regular soap, body wash or gel, as these contain a higher pH level and non-hypoallergenic fragrance ingredients that are not correctly formulated for intimate skin. Products with a different pH level than the vulva can disrupt your vulva’s natural pH, leading to irritation, discomfort and possibly infections.
