Beauty a beauty therapist...we love product!!

best thing to do is..

Drink plenty of water.
Having dry skin does mean wrinkles so you want to keep you skin hydrated and moistured.. even a nivea cream etc is better then nothing..
People with oily skin dont get as many wrinkles as them with dry.. so yes HYDRATE
healthy diet.. well that is a given for a healthy body as well.
but even if you can cleanse your face.. use something with no soap as that will dry it out even more.. so a cream cleanser is great
Also, wearing a hat and saying out of the sun.. or wear sunscreen is nearly #1 on the list.

Good luck!
