Amazing Hydration — My Skin Drinks This Up!
I absolutely love this serum! I’ve tried a lot of hyaluronic acid products, but this one from Isntree is on a completely different level. The ultra-low molecular formula actually sinks into my skin instead of just sitting on top, and I can feel the hydration immediately. My skin looks plumper, smoother, and way more refreshed, especially in the mornings. It layers perfectly under moisturizer, makeup, and sunscreen without pilling, and it never feels sticky or heavy. I also love that it’s vegan and gentle enough for my sensitive skin. After a couple of weeks, my complexion looks noticeably healthier and more radiant. If you want deep hydration that actually works, this is definitely the serum to get. I’ll be repurchasing for sure!

Amazing!
A nice lightweight hydrating serum! It also helped me with my redness (I have sensitive skin) 😊❤️ When I was done, I notice that my skin felt a little dry, so yeah, a perfect addition for dry, sensitive skin!

Love it!
I absolutely love this lotion! The texture is smooth and creamy without being greasy, and it absorbs quickly into the skin. It has a light, pleasant scent that isn’t overpowering, and a little goes a long way. I’ve noticed a real improvement in how my skin looks and feels since I started using it. Definitely a new favorite — highly recommend!

Fantastic Product A+
Like most people I was debating between this HA serum vs the Torriden, glad I went with this one. Slightly thicker consistency than the Torriden, yet lightweight provides hydration can be added to your cushion foundation for a extra glow. Torriden did not do much my skin, felt that it just sat on my skin. This HA serum provides overall hydration, glow and can be layered well with other skincare. Another plus my teenager can also use this without any problems. A+ product in my opinion.

molto leggero e acquoso come promette. Rispetto agli altri sieri all’acido ialuronico provati è molto più confortevole sulla mia pelle e si stratifica bene anche con gli altri prodotti.
