Is this safe for 0-6 month old newborns to use Hydrolyzed Casein?
ℹ️General Overview
For newborns and babies 0-6 months this ingredient is generally low risk but should be treated with caution because it is derived from milk. It is not expected to be toxic, but it can trigger an allergic skin reaction in infants who are sensitive to cow milk proteins.
✅What to Do
If your baby has a known cow's milk allergy or a family history of milk allergy, avoid products with hydrolyzed casein on the baby's skin. For other infants, prefer products formulated specifically for babies and without unnecessary protein additives. If you must use a product with this ingredient, test a tiny amount on a small area of the baby's thigh or arm and wait 24–48 hours to watch for redness, rash, or swelling before using more widely.
⚠️Warnings
Do not apply to broken, inflamed, or very irritated skin. Stop use and contact your pediatrician right away if you see a rash, hives, swelling of the face or lips, difficulty breathing, or any sudden change — these can be signs of an allergic reaction. The judgement that it is not expected to be toxic comes from Environment Canada and review guidance from the Cosmetic Ingredient Review, and some product standards restrict its use unless manufacturers provide safety data; this is why extra caution is warranted for infants.
