Maximize the technology of Dove Men+Cool silver Antiperspirant Deodorant by applying it at night. Why? The key lies in the condition of your skin; not only is your body’s perspiration rate higher in the morning, but a hot shower will also open your pores, making it less receptive to any antiperspirant applied afterwards. Your skin is drier and cooler at night, so it has the best possible opportunity to sink in.
