About this ingredient
Lactoferrin (INCI Lactoferrin) is an iron-binding protein found in milk. In cosmetics it is positioned as support for keeping skin clear and soothing irritation, within products for blemish-prone skin. On efficacy it is worth being clear. Lactoferrin has documented antimicrobial activity in the lab, but how it performs inside a topical cream is poorly studied independently. The maker draws the link to skin clarity; clinical data in cosmetics is scarce. Treat it as a support component, not as an active with proven efficacy. Applied topically it is not systemically relevant, so it can be used during pregnancy and breastfeeding without issue. Tolerability is good. Irritation and allergy potential are both low, suitable for sensitive skin. If you have a known milk protein allergy, it is worth checking the formula. There is no data on relevant comedogenicity.
