Everyone might have to deal with a problem of skin dehydration expecially during the windy day with very low temperature, spend all the time in air-conditioned area, or spend long time on the flight abroad. The very basic solution which is well-known among all of us would be "drinking more water" and "applying moisturizer". However, in some case, skin dehydration still exists even though they have drunk much more water and apply moisturizer already. This problem will occurred when you are getting older and it's the major cause of pre-mature aging and wrinkles.
