If you would make a top 10 list of things we don’t appreciate as much as we should, water would be in the top 5. Yes, those of us who live in the developed world, where an abundance of drinking and technical water exists, tend to take it for granted. But then again, there’s the fact that more than half of our bodies is actually water. And the fact that we can’t imagine life existing without it so much so that wherever in the universe we search for life we always look for water first. Water is that important, and we couldn’t survive without it for more than a few days.

But what role does water play in how our skin looks, and even more important, works? Well, for all the cells in the body, water is much needed because things get dissolved in it. And by things, we mean both nutrients that feed the cells, and the waste that is left after the feeding. Serving as an important part of the body’s transport system, water is directly responsible for proper functioning of all the cells in all the organs, including the skin. Without it, the cells in the organs wouldn’t be able to perform their duties. For skin cells, that means they wouldn’t be able to protect us efficiently from outside invaders like bacteria and viruses, and the skin wouldn’t be as effective in repairing the damage it takes on the job.

To put it bluntly, without proper hydration, the skin would become dry and cracked, make you more prone to infections, and it would degrade and age more quickly. But there’s a question looming – do we really need to hydrate from both the inside and the outside?

The short answer is – yes. Hydration from the inside is not optional, but the topical products that hydrate the skin are important as well. Now, people did survive for centuries without moisturizers, but then again, in this day and age, if you want your skin to be as healthy as possible, it’s likely you’ll need a good moisturizer. Even if you have normal skin, not too dry and not too oily, you’ll need to moisturize at least in the winter, when the air is drier and it’s harder for the skin to keep the moisture in. And if you have oily, or dry, or mixed skin, you’ll need to moisturize it to prevent it from becoming even oilier or drier, at the least.

So, in a nutshell – water is good for the skin because the skin wouldn’t function properly without it, and that’s a hard fact. Of course, it’s up to you to determine how much hydration your body and your skin need, but there’s no way to get around it. We need water, and since our skin is a part of us, it needs water too, so we must make sure to provide it.
