Lactose is milk sugar and, when it’s in baby creams or powders, it’s usually safe for newborns and infants. It rarely causes irritation. The biggest small risks are leftover milk proteins (which can bother babies with a real milk allergy) and the product getting contaminated if it isn’t well preserved.
Use only products made for babies and from trusted brands. Don’t put products with lactose on open cuts or raw skin. If your baby has a diagnosed milk allergy, avoid products that list lactose or ‘milk’ ingredients. Keep containers clean and tightly closed and throw out products past their use-by date. If trying a product for the first time, apply a tiny amount to a small patch of skin and watch for 24–48 hours.
Avoid use if your baby has a known milk allergy — milk proteins can sometimes be present in lactose (this is noted by food and safety regulators). Watch for redness, swelling, blistering, increased heat, or pus — these could be signs of irritation or infection, possibly worsened if a product is contaminated because preservation is poor. Some safety review panels and industry guidelines recommend controls on purity and manufacturing of lactose used in cosmetics; prefer products that list preservatives and are labeled for infant use.
