      Reviews

      "The texture is light and watery, like a serum. It absorbs quickly without any stickiness, so it's perfect as the first step in your skincare routine. When applied before heavier creams, it seems to work well with the subsequent products. While the moisturizing effect isn't extremely long-lasting, it maintains a subtle hydration. There's no sticky or heavy feeling right after application, and even when dryness starts to set in by the afternoon, it wasn't too uncomfortable. Those with extremely dry skin in winter might need additional moisture, but for daily use, it's more than adequate."

      — Yuridia (5/5)

      "My skin has been really dry lately, so I decided to try a serum, and the Isntree Hyaluronic Acid Serum exceeded my expectations! It truly lives up to its name as the epitome of hydration. When I first applied it to the back of my hand, it felt light and watery, but I was amazed at how quickly it absorbed into my skin. ✨"

      — Sonji (5/5)

      "I've been using the Isntree Ultra-Low Molecular Hyaluronic Acid Serum (50ml) consistently and wanted to share my thoughts. With the changing seasons, my skin has been getting dry and tight, but incorporating this serum into my morning and evening skincare routine has noticeably improved hydration. The price is reasonable for a high-moisture serum, making it a great option for daily care without breaking the bank."

      — Junia (5/5)

      "After using it for a few days, the biggest improvement I noticed was in reducing inner dryness. The tightness in my skin definitely decreased, and it felt more hydrated from within. However, since my skin is extremely dry and dehydrated, the serum alone wasn't quite enough to fully address the dryness. So, I tried layering toner twice before applying the serum, and from then on, my skin texture felt noticeably smoother and overall healthier."

      — Lucetta (4/5)

      "I first discovered Isntree through my girlfriend's recommendation and tried a few products. Now that we're living together, I've ended up with quite a collection! I have extremely oily, acne-prone skin, and the Hyaluronic Acid and Onion lines have worked wonders for me. The products are so gentle that I only use the Milk line to remove sunscreen, and I'm extremely satisfied. However, after using nearly 10 bottles of the serum, I noticed that towards the end, the product at the bottom doesn't come out with the dropper and is hard to get even when I turn the bottle upside down. Despite this, I'm grateful for the great products and will continue to be a loyal customer. Go Isntree! 💙"

      — Jaylynn (5/5)

      "If you're like me and struggle with dryness, constantly battling dehydrated skin, this is for you. Every morning my makeup would flake, and by afternoon my skin felt tight and parched. No matter how much skincare I applied, I couldn't solve the underlying dryness, leaving me frustrated. But I've finally found my holy grail product! It's the Isntree Hyaluronic Acid Ultra Low Molecular Serum."

      — Kimora (5/5)

      "I had been using the hyaluronic acid essence and decided to try the ultra-low molecular serum as well. It's a bit more watery compared to the essence, so it absorbs quickly. It seems to provide excellent hydration, and I'm very satisfied with it."

      — Dayamai (5/5)

      "I tried a sample and loved it so much that I decided to order it. At first, it made my face look incredibly dewy, but now I'm not sure if it's just me, but the effect seems to be diminishing. I think I need to keep using it consistently to see the results."

      — Meriem (4/5)

      "I think I received extra mask packs because I purchased over a certain amount. When I tried them, they seemed like a lighter version of the hyaluronic acid mask packs I used before, but with upgraded material."

      — Keisha (5/5)

      "I realized this is what a great daily serum should be like."

      — Madelynn (4/5)
