Having talked about the hydration from within, I also need to mention the outside. As the air gets drier it is necessary to moisturise your skin, nails and hair. You can increase the use of your everyday products or may even get some other hydrating products. However, pure oils are in my opinion the best supporters. Coconut oil, rosehip oil, tea tree oil and many other oils come with sum-less benefits and are a cheap and sustainable alternative. Anyhow make sure to moisturize your skin regularly.
