Reviews Summary
Customers say this serum provides deep hydration and makes skin feel plump and soft. Many reviews mention improved texture and a noticeable glow after regular use. While most praise its lightweight feel and quick absorption, some note issues with pilling under makeup. The serum works particularly well in evening routines, though experiences vary with dry and sensitive skin types. Common feedback includes its effectiveness at strengthening the skin's moisture barrier. Some users report it works better than traditional hydrating serums, while others find it less effective.

    Love this

    I’ve been using the hyaluronic acid for a while now and decided to change for a bit. It’s as good on my skin as the hyaluronic acid but it’s good to try something different. No complaints.

    Nice Serum

    Nice serum, especially in the summer when my skin needs some more hydration. You don’t need a lot. The packaging is oke. It would be nice to see how much is left. But I really don’t like the smell, it’s chemical/chlorine like.

    Great product, my skin has been so much better following the use of this product and my skin is looking so much healthier. Was having loads of breakouts prior and now my skin is great since I’ve been using this product
