Hydration Benefits of Hyaluronic Acid
Hyaluronic Acid—it’s actually a natural substance your body makes, mainly hanging out in your skin, joints, and eyes. It’s like nature’s secret weapon for keeping things moisturized and glowing.
This magical ingredient can hold up to 1,000 times its weight in water, making it a hydration superhero for your skin.
So, when you see Hyaluronic Acid (or HA or HYLA) on the label of our Silk pillowcases or sleep masks, you can rest easy knowing it's working overtime to keep your skin plump, hydrated, and looking younger as you sleep. Because when it comes to beauty sleep, we’re all about boosting hydration—naturally.
"The enVy® brand is really a playground for us to see how far we can push the technology, design, and innovation of our sleep fabrics… most notably our pure 100% SILK."

How Our HYLA Technology Works
What’s So Great About Hyaluronic Acid?
When it comes to skin, Hyaluronic Acid is like the ultimate moisture magnet creating soft, supple skin that feels plump and hydrated—like a drink of water for your face!
As we age, our natural hyaluronic acid levels dip, which contributes to the fine lines and wrinkles we all know (and love to complain about). That’s why. we added this powerhouse ingredient to the SILK in our specialized pillow, sleep masks and dedicated Silk pillowcases.
The bonus? It encourages your skin to start making its own hyaluronic acid again—talk about a beauty comeback!
Where Does Hyaluronic Acid Come From?
We’re all about keeping things natural, and our hyaluronic acid is no exception. It’s made through a cool biotech process called bio-fermentation. This means it’s created with the help of lactic acid bacteria (yep, those tiny little guys are working hard behind the scenes). Once produced, it’s purified, and infused into our specialized COPPER + HYLA silk products.
The hyaluronic acid we use is all-natural, biodegradable, and kind to the planet. It’s made with a green chemistry process, which means minimal energy, water, and waste. And for our eco-conscious folks, we’ve got you covered—it's organic hyaluronic acid, too!

📏 Why Size Matters — A Lot:
Not all HA is created equal — and size is everything when it comes to skin benefits.
High Molecular Weight HA sits on the surface of the skin — but it doesn’t go deep.
Low Molecular Weight HA — like sodium hyaluronate, which is used in your COPPER + HYLA pillowcases and pillows — is small enough to penetrate deeper into the skin, where it can:
Boost hydration from within
Improve elasticity and firmness
Reduce wrinkle depth
Calm inflammation
💡 That’s why sodium hyaluronate is considered the gold standard in skincare — it’s more bioavailable, more absorbable, and more effective at tackling the need for skin hydration.
Hyaluronic Acid Infusion Science & Care FAQs
What is hyaluronic acid and why is it used in sleep products?
Hyaluronic acid is a naturally occurring molecule in the skin that attracts and retains moisture. When infused into silk sleep products, it helps support overnight hydration during the skin’s natural repair and regeneration cycle.
Does hyaluronic acid actually work while I sleep?
Yes. Sleep is when skin repair and regeneration peak. Hyaluronic acid supports hydration during this critical overnight repair window, helping skin feel smoother, plumper, and more comfortable by morning.
Does the hyaluronic acid stay in the pillowcase permanently?
The hyaluronic acid infusion is not permanent and will gradually diminish over time, typically after 30+ washes, depending on care.
The good news: the pillowcase also contains permanently infused COPPER, which continuously self-sanitizes the fabric. This means the pillowcase stays cleaner between washes, reducing how frequently it needs to be laundered and helping extend the effective life of the hyaluronic acid infusion.
How is your hyaluronic acid different from other HA technologies?
Our hyaluronic acid uses a small molecular structure, which allows for better skin penetration and hydration support.
Many conventional hyaluronic acid technologies use larger molecules that tend to sit on the surface of the skin rather than being easily absorbed.
Can I use HYLA pillowcases with my regular skincare routine?
Absolutely. HYLA pillowcases work with your skincare routine by helping reduce overnight moisture loss and friction. They do not replace topical skincare products but support their performance while you sleep.
Is HYLA silk suitable for sensitive or acne-prone skin?
Yes. Silk is naturally smooth, breathable, and gentle on the skin. Combined with hydration support from hyaluronic acid and the antimicrobial benefits of copper, these pillowcases are well-suited for sensitive, reactive, or blemish-prone skin.
