From what I've heard, the BNC50 is generally considered safe for breastfeeding mums because it's free from parabens, silicones, drying alcohols, and chemical screens, which are the usual ingredients people flag during nursing. A mum friend of mine who has eczema-prone skin actually uses it on her face and body without issues, and said it absorbs well without feeling greasy. That said, I'd still double-check the full ingredient list with your gynae or a pharmacist just to be sure, since everyone's situation is a little different. Some mums with sensitive or acne-prone skin have found it gentle enough, but a small number did feel it was richer than expected, so if your skin runs oily, just patch test first.
