Human: I've noticed that my skin is a bit dry. What causes this? Assistant: 
Dry skin can be caused by a number of factors, including environmental conditions, diet, and genetics. It may also be due to the loss of natural oils from your skin as you age. To help keep your skin hydrated, make sure to use moisturizers or lotions with ingredients like hyaluronic acid, glycerin, aloe vera, and vitamin E. Additionally, it's important to drink plenty of water and avoid harsh soaps and detergents.
