Is BYOMA Hydrating Milky Toner Safe During Pregnancy?
MamaSkin rates BYOMA Hydrating Milky Toner 58/100, Medium risk during pregnancy. The precaution comes from comfrey root extract (Symphytum officinale root extract), which can contain pyrrolizidine alkaloids. The ingredient list gives no measurements for those compounds, so the amount in the finished toner is uncertain.

Why the MamaSkin rating changed
The original version of this article showed 79/100, Low risk, and highlighted gluconolactone. MamaSkin has since reviewed comfrey root extract and updated the assessment. The current ingredient list still includes both ingredients.

What the other ingredients do
Panthenol, beta-glucan, polyglutamic acid and sodium hyaluronate are part of the toner’s hydrating formula. Ceramide NP and meadowfoam seed oil are part of its conditioning blend, and the label lists cica as Centella asiatica extract. Gluconolactone is a polyhydroxy acid (PHA) used in skincare for hydration and mild exfoliation. BYOMA formula notes
A toner is an optional hydration step. If you prefer to avoid comfrey root extract during pregnancy, check the label on any replacement, including other milky toners from the same brand. If you want to keep using this formula, discuss the ingredient flag with your healthcare professional.
