For newborns and babies 0–6 months: this ingredient is generally considered low risk in normal cosmetic amounts, but there is little specific testing in infants. Because baby skin is thin and absorbs more, we should be careful.
Prefer baby-specific products without this ingredient for infants under 6 months. If a product with Copper PCA is recommended by a pediatrician, use a very small amount on a small area first and watch the spot for 48 hours for any redness, swelling, or rash. Do not apply to broken or irritated skin, keep away from the mouth and eyes, and wash your hands after applying.
Watch for signs of irritation (redness, swelling, blisters, rash) — stop use and contact your pediatrician if these occur. In severe reactions (trouble breathing, swelling of the face or lips) seek emergency care. Note: Environment Canada flagged that this chemical can persist and build up in wildlife, and the U.S. Environmental Protection Agency reported animal studies showing organ effects at moderate doses; these findings are why we recommend extra caution for very young babies.
