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.

    Repairs skin from inside out

    I have very sensitive skin and often react to things and when I slowly can reintroduce skin care against then this is the first thing I start to use. It really helps speed up the process and get my skin back to a happy, healthier and smoother state. Love it!
