Ashton Kutcher and Mila Kunis recently disclosed that they only bathe their children when they se

e dirt on them and avoid using soap on their own bodies.

The actors who share two kids daughter Wyatt, 6, and son Dimitri, 4, discussed their family’s approach to hygiene when they appeared on the latest Armchair Expert podcast, hosted by Dax Shepard and Monica Padman.

The conversation began when Dax told co-host Monica that she should not be excising the natural oil on her skin by using soap every day, to which Kutcher and Kunis agreed, saying they only wash vitals every day.

In response Monica replied: “I can’t believe I am in the minority here of washing my whole body in the shower. Who taught you to not wash?”

Kunis, who was born in Soviet Ukraine, then explained that she hardly ever had a shower during her childhood because they didn’t have hot water at home: “I didn’t have hot water growing up as a child, so I didn’t shower much anyway.”

She added: “But when I had children, I also didn’t wash them every day. I wasn’t that parent that bathed my newborns – ever.”

Ashton added: “Now, here’s the thing: If you can see the dirt on them, clean them. Otherwise, there’s no point.”

The same principle also applies to the couples’ hygiene habits as they don’t wash their bodies with soap everyday.

“I wash my armpits and my crotch daily, and nothing else ever,” Kutcher revealed. “I got a bar of Lever 2000 that delivers every time. Nothing else. I do have a tendency to throw some water on my face after a workout to get all the salts out.”

Kunis added that she washes her face twice a day.

According to the American Academy of Dermatologists, although daily bathing is safe for children aged 6–11 years, they only need to take a shower every few days.

The Mayo Clinic advises against washing a baby every day, stating: ‘There’s no need to give your newborn a bath every day. Three times a week might be enough until your baby becomes more mobile. Bathing your baby too much can dry out his or her skin.’

Medical News Today reports that older adults may not require a shower every day to maintain the level of cleanliness necessary to protect their skin, ward off infection, and meet general standards of grooming. It added that, taking a shower once or twice a week can often be sufficient to meet these criteria, and people can use warm washcloths in between to stay feeling fresh.
