Get yourself some steam – In addition to drinking copious amounts of water, this is the best way to cheat and add water back into your skin without all the work. Sitting in your steam room at the gym helps, but a good humidifier in the bedroom will give you “vacation skin” on a regular basis by adding the right amount of moisture to your environment to prevent dryness and premature aging. Seriously, try it.
