For newborns and babies (0–6 months): be cautious. Propylene glycol can irritate sensitive skin and helps other chemicals get through the skin. Babies’ skin is thinner, so they can be more affected.
Avoid products with propylene glycol on baby skin unless a doctor says it’s needed. If you must use a product: use a very small amount, only on a small area, avoid putting it under diapers or tight clothing, and choose products labeled for infants or that list low concentrations. Stop use and call your doctor if you see redness, rash, swelling, or any unusual behavior.
Do not use on broken or inflamed skin. Skin irritation is reported by medical sources (U.S. National Library of Medicine). It can increase absorption of other ingredients (Cosmetic Ingredient Review). Some government reviews have raised concerns about organ system effects at higher exposures (Environment Canada). If product use is recommended by a healthcare professional, follow their instructions and report any skin reaction right away.
