Hindi naman bawal, mama! Liquid foundation and concealer are generally safe to use while breastfeeding kasi hindi sila napupunta sa milk supply, they stay on your skin lang. A few of us moms just make sure na we wash our face really well before feeding, especially if the products get near the chest area, pero honestly most of us don't stress too much about it kasi it's topical lang and hindi absorbed directly into the bloodstream in a way na makakaapekto sa baby.
