Reviews Summary
Customers say this serum feels lightweight and absorbs quickly into their skin. Many note visible improvements in skin plumpness and texture after regular use. The formula works well in layered routines, with users particularly appreciating its non-sticky texture and smooth application. While some mention it feels slightly sticky initially, most find it blends seamlessly. Regular users report softer, more supple skin, though a few haven't noticed significant results. The serum receives praise for its gentle formula, with several mentioning it works well for sensitive skin.

    Wonderful!

    Really noticing more plump skin after just a few uses. Love the Matryxyl 3000 in this.

    Goes into the skin really well, a light serum which you can top off with more if needed
