Is drinking water good for your skin?

Is drinking water good for your skin?
The idea that you’ll have a better complexion if you stay hydrated is commonplace, so we were surprised to discover the lack of evidence to back this up. If you have been working hard to achieve smooth skin that glows, the chances are that you will have read about the virtues of drinking lots of water.


What we know

Our skin is our largest organ. Covering the whole body it makes up about 16% of your overall body mass and is approximately 2 millimeters thick.
Our skin does a multitude of jobs for us including
    1. 1. Protecting your body from environmental stressors like germs, pollution, radiation from the sun, and more
    2. 2. Regulation of your body temperature
    3. 3. Receiving sensory information
    4. 4. Storing water, fat, and vitamin D
      In addition to all the functions our skin carries out, our skin is also what we present to the world. So there probably aren’t too many of us who would say “no” to healthier and younger-looking, more vibrant skin. Our skin is made up of three layers.
      Structure of skin
      Figure 1
      The subcutaneous tissue (fat) layer makes up the bottom layer. The middle layer is called the dermis. And the top layer is the epidermis. The outermost layer of the epidermis is called the stratum corneum. This important membrane keeps bad things from entering the body. It also plays a role in making sure that too much water doesn’t leave our bodies. In other words, it helps keep the skin hydrated by preventing water evaporation. This layer does more than act as a barrier, the cells in the membrane can also absorb water, but that doesn’t mean you can lie in a pool of water and absorb it or drink it and have anti-aging success, but it does mean that a moisturiser might be absorbed.


      What the Science Says


      There isn’t a lot of science that’s studied water and anti-aging skin benefits. In one small pilot study,  researchers looked at how water intake affected skin. More specifically, they tested what type of water --mineral or ordinary tap -- would yield the best results. They found that drinking 2.25 liters (9.5 cups) of water daily of mineral or ordinary tap water for 4 weeks did have some effect. But results were mixed. People who had routinely drunk little before the start of the study did see an increase in skin thickness. As you age, your skin loses density because of collagen and elastin breakdown and leaving you with some sagging, fine lines, and wrinkles, plus you can’t retain moisture that well, as you age, skin thins. Drinking more water really won’t help with this.  One time more water will help is during periods of high temperatures when your chances of dehydration skyrocket as temperatures continue to climb, drinking more water is vital.  

      The takeaways


      The doctors do agree that water is important for good health. But minimizing wrinkles and perking up your skin really comes down to care from the outside and the inside. Drink water, limit alcohol, don’t smoke, moisturise, wear sunscreen, and improve your nutrition. The takeaway is pretty clear: Drink your water because it’s important to your good health. Just don’t expect it to get rid of your crow’s feet.
