Beauty Science: Does drinking water REALLY help with dry skin?

Hi everyone!

I wanted to make this post about dry skin, even though spring time is right around the corner. Dry skin is a condition that plagues many of us despite warmer weather. And with my recent mentions of dry skin and water, I want to address a beauty myth!



So here my the question for you...

Does drinking water really fix dry skin?

We've all heard it many times. Family members, friends, neighbors, and plenty of internet skincare websites will tell you to, well...drink more water to fix that dry skin!!

Is it true?



Water is a magnificent thing. We all know this. We have all been taught this. And dehydration can cause many problems.

We know that dehydration can cause splitting headaches. But this only occurs when it's significant dehydration. (Yes, the simplest example would be alcoholic beverages!) Mild dehydration can causes the skin to lose moisture. (Think dry lips and cracked knuckles!)

A 10-20% decrease of water in the skin is enough to cause dry skin symptoms. But does this mean we can just drink that water content back?

No. Drinking more water simply means more trips to the bathroom! We're not camels, we can not store water once we reach our maximum capacity (different for everyone!). So the kidney simply filters and filters, and we pee!

So excess water won't moisturize your skin, it will only make you pee more. Dehydration however, can definitely dry out your skin.

Our skin is a barrier to the outside world. This means it keeps the bad stuff out and the good stuff in. That flaky and damaged skin won't keep the moisture in.

Alright, what do we do with dry skin if we can't chug 5 liters of water a day to fix it? We moisturize. The products on the market like lotions and creams are designed with specific ingredients that form a barrier on our skin to prevent the skin from losing moisture.

So to fix dry skin, we can drink water to become hydrated once more and we can use moisturizers to keep the moisture in.

The best course of action of course is to prevent dry skin. We can avoid things that damage the skin, like irritating ingredients from household cleaners or sun damage.

There are a few clinical studies which supported the idea that it is not the amount of water you drink, it is the minerals in the water which may help with your skin.

Think about it this way, if all that is needed to cure dry skin is to drink water, then why are there so many moisturizers out in the market?

So here's the bottom line: 


Water is great for you in many ways,
but it is not going to "fix" dry skin!

  1. Love this! Can definitely vouch for this. Had overly dry skin during December into January and no matter how much water I drank, it didn't help. I had to switch my moisturizer to one that was heavier and thicker than what I was using.

    1. Yep! I use heavier and thicker moisturizers in the winter time and lighter ones for summer time :D This way, I keep my skin happy in the cold weather and won't clog up my skin in the summer.

  2. if your intake of collagen is higher, your skin will be more supple. It's an old myth but I think it's true :)

  4. Yeah, I figured... :-) I do drink lots and lots of water because it's healthy for you, but I don't have perfect skin by any means, so it's pretty clear that it doesn't do much for your skin. Too bad!

    1. Well, water is good for keeping you hydrated, which in turn helps you to keep your skin supple and filled with moisture. A lot of the times, we don't take care of our skin so we lose that water :(

  5. Great post! I always questioned this whole "drink water to moisturize the outer layer of skin" What?! Makes no sense. I'm assuming staying hydrated (as in consistently - not chugging water in bursts) will do good things for the body overall, including skin, but that's different than using water as a fix.
