Questions you may still have
Does breast milk soap treat eczema, psoriasis, or diaper rash?
We have no product-specific clinical evidence that it treats these conditions. It is a cleansing product, not a treatment; speak with a clinician about diagnosed or persistent skin problems.
Is a soap made from breast milk the same as applying fresh breast milk?
No. The formula and soapmaking process are different. Biological properties of expressed milk should not be assumed to carry over to the finished bar.
Can I use a custom breast milk bar on my baby?
The service is not represented as suitable for infants. Consult your pediatrician before selecting a cleanser for a baby.
Can I send my milk without contacting the studio first?
Please confirm the current handling and shipping instructions with us and your carrier before dispatch. The service page explains the required amounts and process.
