Hi momsh! I haven't tried Maxi-Peel Zero myself kaya hindi ako makakapayo talaga, pero alam ko some of my mum friends who are breastfeeding din ay nag-hesitate sa chemical peels dahil hindi sure kung maipapasa sa baby through breastmilk. Better check with your derma or OB po about what's safe while you're still nursing, they'll know best kung safe lang talaga kahit with continued breastfeeding. Pero if you're concerned about your skin, they might recommend gentler options muna na proven safe for nursing moms!
