Our photo-therapy mask is the best on the market! It stays in place better and longer than any other. It blocks 90% of the light, most masks allow the light through, and molds to the face to prevent light from coming in around the sides. It is comfortable for the baby and therefore if your baby is nested they will lay quite better and longer helping to keep the mask on the way you want it and reduces stress. It is easy for the nurse to apply, all this maks her job easier and more efficient.
