Rejuvenated H3O Hydration review

“Don’t be such a snob! Hydration is the foundation of youthful skin.” That’s what I’d tell young Gio if I could go back in time.

When I first started getting into skincare, I didn’t value hydration at all. I was in my early 20s, drinking my 8 glasses of water a day and living in Italy, where the weather is sunny and warm and even the winters are mild.

Why bother with hydrating masks and Hyaluronic Acid serums when my skin already had all the moisture it needed? Keep those and pass me the antioxidants, thanks. Back then, if a product wasn’t antiaging, it didn’t exist for me.

I was stupid enough to believe it would be like that forever. Turns out, forever ended 3 years ago when I moved to London. It’s not as cold as they say, but the wind is unrelenting.

Within a few months, it had sucked my skin completely dry. My skin was flaking, my complexion had lost its glow, and my face had aged 10 years overnight.

Those hyaluronic acid serums and hydrating masks I despised so much? They saved my skin. Lesson learned: the best antiaging products in the worlds won’t help you if your skin isn’t hydrated.

Why Hydration Is The Foundation Of Youthful Skin

Did you know that 60% of your body is made of water? Just to give you an idea, your brain is made of up 73% water. Your lungs, 83%. And your skin, roughly 64%.

You know what that means? Your body can’t function without water. When you’re dehydrated, all kinds of bad things happen. You feel tired and dizzy, can’t concentrate, have headaches and muscle cramps, struggle with insomnia… and that’s just the tip of the iceberg.

Dehydration takes it toll on the skin, too. Now moisture’s gone, your skin is shrivelling like an old prone. New wrinkles spring out of nowhere. Those you already have look 10x worse. All the glow’s left your skin. And the flakes!

Yep, moisture helps skin exfoliates itself on its now. Without it, dead cells stay on the surface of your skin, giving you a bad case of the flakes.

Exfoliation isn’t the only thing your skin can’t do without enough moisture. Cellular hydration also triggers the release of growth hormones and DNA repair, processes that help the skin repair itself from the damage it sustains every day.

Truth bomb: dehydration doesn’t only make you look older. It makes you ages faster, too.

How Do You Keep Your Skin Hydrated And Healthy?

Three ways:

  1. Drink water: Whenever possible, drink plain old water instead of soda. You can add some lemon or mint leaves for more flavour. But if that’s still too much for you, good news: fruits and vegs count, too. They’re packaged with water, remember?
  2. Use hydrating skincare products: I love anything with Hyaluronic Acid. This moisture magnet can attract and bind to the skin up to 1000 times its weight in water.
  3. Take hydrating supplements: Supplements like Rejuvenated H3O Hydration contain nutrients that can hydrate skin cells from within.

I’ve been doing steps 1 and 2 for years, but now I’m in my late 30s, I feel the need to step up my hydration game a notch or two. Anything to slow down the hands of time, you know?

So, last month I added Rejuvenated H3O Hydration to my water. Did it work? Let’s find out:

What’s In Rejuvenated H3O Hydration?


The key ingredient in Rejuvenated H3O Hydration? Hyaluronic Acid.

Hyaluronic Acid is a humectant: that’s how scientists call ingredients that can attract water from the environment (including your own body) and bind it to the skin.

Hyaluronic Acid is the best at this. Like I told you above, it can bind up to 1000 times its weight in water. That’s a waterfall of extra water for your skin.

The catch? Hyaluronic Acid is too big to penetrate skin. When you apply it topically, it just hydrates the surface of your skin.

Good news: drinking Hyaluronic Acid works too. Studies show that oral supplements increase hydration, make skin suppler and brighter and even reduces the appearance of wrinkles!

Rejuvenated H3O Hydration doesn’t just hydrate skin. It’s also packed with antioxidants that help you fight wrinkles:

FYI, the amount of antioxidants here is low. But hey, every little bit helps, right?

Rejuvenated H3O Hydration is a pink powder. Yes, it makes the water a little pink – that alone is reason enough to use it (can you tell pink is my fave colour?).


The taste ain’t bad. I wouldn’t call it good, either. It’s not delicious as a berry smoothie or hot chocolate, but it ain’t bitter or unpleasant. More like bland. It doesn’t taste like much of anything. It’s kinda like drinking… water.

How To Use It

  • One or two servings a day tops.
  • Add one scoop to a glass filled with 300ml of water (or your preferred beverage), mix it in with a fork and drink.
  • You can use a small shaker for mixing it in.

Performance & Personal Opinion

Did drinking this supplement made a difference in my skin? Yep. I kid you not, a couple of days after I started pouring Rejuvenated H3O Hydration into my water, my skin already felt softer and suppler. It looked a little brighter, too.

A month later, my skin looks healthy. I can’t say the difference is dramatic – probably because since my first winter in London, I make sure my skin is always fairly hydrated.

But the supplement did give it that extra little boost. You’ll notice it more when you’ve had a poor night sleep and the next morning your skin isn’t the worse for it. 🙂

Who Is This For?

It’s best suitable for dry and dehydrated skin.

Who Is This NOT For?

If your skin already has all the moisture it needs, you do NOT need this.


The box contains 24 small sachets. It’s also available in pouches (30 servings).
