2022 packaging, same formula

As of mid-2020, the Hyaluronic Acid Airy Sun Stick is a part of IsNtree's newest line of Hyaluronic Acid Sun Protection products! Despite the small size of this product, it definitely packs a punch.

How?

Well, to start off, you have the impressive and reliable SPF 50+ PA++++ rating, making sure that your skin is well protected from the damaging ultraviolet rays of the sun. No room for UVA and UVB to reach your skin. Beyond that, one of the key features of this new line of products includes 8 Different Types of Hyaluronic Acids included as a part of its formulation, ensuring that this vital ingredient reaches the various levels of the skin, helping to reinforce and replenish moisture levels within the skin. The value doesn't end there though - ingredients like French Coastal Pine Bark, Bamboo, Kelp, Aloe Vera, and Yam Root Extracts help to cool down and moisturize the skin, while offering the entire formulation a mild and non-irritating ingredient profile.

One application is enough to get you started...

...but don't let it end there. Sun Protection is most effective when it is re-applied every couple of hours or so, as it breaks down and wears off under constant exposure to the sun's ultraviolet rays. Nothing unique to IsNtree for this one, but is universal to all sunblocks.

With IsNtree though, the powerful SPF 50+ PA++++ formulation makes sure that your face is protected from the sun, no matter where you are or what you do.

Teardrop Shape
Unlike the 'rectangular oval' shape that you might find with other sun sticks, this one has been designed to be in the shape of a teardrop. Why?


Covered Skin = Protected Skin
Effective application. Get into the nooks and crannies, like right beside your nose, with the thinner part of the stick! Protection is only possible when the skin is properly covered.

Complete Coverage
The tear-drop shape lets you get the complete coverage you need to make sure that every inch of your skin is protected from ultraviolet rays

8 Types of Hyaluronic Acid
Hyaluronic Acids are not at all the same, which is why IsNtree has gone to great lengths to include 8 different types of it in their product. The difference 'weights' or 'sizes' of the Hyaluronic Acid is one of the key reasons why - different sizes reach different depths of the skin, with smaller ones reaching deeper depths. Why does this matter? For comprehensive coverage. Making sure the surface of the skin is moisturized is a noble start, but making sure that the deeper layers are also moisturized is even better.


How to Use
After you have finished the entirety of your normal Skincare Routine, including a toner, serum/ampoule, and cream, is when this Sun Stick is designed to be used. Just make sure that all the products used in the other steps have first been absorbed by the skin before applying the sun stick to avoid the product being excessively smudged here and there.

Great product! I love the feel of these.
Size: Queen, Color: White
“I recently purchased the Serta Power Chill Cooling Pillow Protectors, and they have been a game-changer for my sleep comfort. These pillow protectors have exceeded my expectations in several ways. First and foremost, the cooling technology is fantastic. I tend to sleep hot, especially during the summer months, and these pillow protectors have made a noticeable difference. They keep my pillows cool and comfortable throughout the night, which has led to more restful and uninterrupted sleep. The fit is also excellent. They easily slip over my standard-sized pillows and stay securely in place without any annoying bunching, wrinkles or slipping during the night. And the zipper is amazing. Having no wrinkles in my cover is easier on my hair. What’s great about these protectors is that they not only keep my pillows cool but also protect them from spills, stains, and allergens. It gives me peace of mind knowing that my pillows are safeguarded while I enjoy a cool and refreshing sleep environment. There is no noise when sleeping on this cover, it’s soft. Cleaning is a breeze. They are machine-washable and maintain their cooling properties even after multiple washes. The quality of the materials used is evident. These protectors feel durable and well-made, promising long-lasting use. While they are slightly more expensive than basic pillow protectors, the added cooling benefits and protection they offer are well worth the investment. They’ve made a significant difference in my sleep quality, and I highly recommend the Serta Power Chill Cooling Pillow Protectors to anyone seeking a cooler and more comfortable night’s sleep.”

Loose on standard pillow.
Size: Queen, Color: White
Too large for standard pillow. It would fit a queen size pillow much better. It does stay cool.

Soft and cool. Very cool. 🧊
Size: Queen, Color: White
I bought these for my memory foam pillow and they’re excellent for cooling it. I use 2 of these on the pillow for maximum chill factor and it works. They’re very soft, the zippers are high quality. Easy to put on with a bit of stretch- generously sized. They’re stain resistant. I’m glad they’re NOT waterproof because they’d be too hot then. They’re very durable. Wash on delicate setting in a mesh bag and air dry and they last long. They’re very quiet- smooth and silky. Definitely recommend!

Cool enough
Size: Queen, Color: White, Size: Queen, Color: White
I thought I had purchased pillows so when I received these I was a little disappointed. However that was 100% on me for not reading the listing and just trusting my search. I decided to give them a try and so far they seem ok. They don’t stay cool even though I have them on cooling pillows. They are super thin but very soft. They fit on my pillows perfectly. I don’t think it has improved my sleep quality but it hasn’t made it any worse either. I don’t think they are waterproof but I don’t really want to test that. I like that the zipper is small and seems to be decent quality. Smelled heavily of chemicals when I first took it out of the package but that disappeared after a few minutes.
