Reviews Summary
Customers say this serum provides excellent hydration with a lightweight, easily absorbed texture. Many reviews mention its effectiveness for dry skin, with users noting their skin feels plumped and soft after application. The serum layers well with other products and a small amount goes a long way. While most praise its non-sticky formula, some find the texture slightly tacky. Long-term users particularly appreciate the larger bottle size for daily use. Reviews frequently highlight its versatility in different skincare routines, though a few mention it didn't provide enough hydration for their needs.

    Best Hyaluronic acid

    This is the best Hyaluronic acid ever. I have used quite a few different brands, one of the very famous ones gets so much pilled on my skin. Been loving this one as no issues and skin feels so plump and soft. Definitely worth the money.
