Reviews Summary
Customers say this serum absorbs quickly and leaves skin feeling plump and hydrated. Many reviews mention its lightweight texture and easy application. The serum blends well with other products, though some note it works best when layered with moisturizer. While most users report improved skin texture and firmness, a few mention needing more time to see results. Reviews frequently highlight its gentle formula, making it suitable for sensitive skin. Common feedback includes requests for a larger bottle size.

    A Have to Have Serum

    Love this serum! I have used other collagen serums, and this is a great one at a great price! Makes my skin feel hydrated and helps with fine lines and wrinkles.

    Will always repurchase!

    So far, decent

    No changes seen to date. New add to my routine which replaces Hyraluronic acid. Would be nice if Inkey would provide more support for mature users - models barely in their 20's talking about "aging" is hardly good marketing.
