which is better for adult dry skin; cool mist humidifier or warm steam vaporizer?
what is better is a moisturizing cream or lotion. exposure to humidity -- steam or cool mist -- is not going to be absorbed through your skin and make it moist again. chronically dry skin is usually genetic (atopic dermatitis eczema) and will likely improve by a good non-perfumed moisturizer and perhaps some topical steroids but if you want to increase your humidity for other reasons the cool mist (the ultrasonic types) are the best in my opinion.
