Sudocrem works in three simple ways to soothe and repair your baby's sensitive skin: an emollient soothes sore or inflamed skin; its components are known for their healing powers; and a light local anesthetic helps to relieve discomfort and irritation. Sudocrem Antiseptic Healing Cream has been mum’s simple, effective ally for over 85 years and is great for soothing sore skin and treating nappy rash.
