Reviews Summary
Customers say this serum provides instant hydration with a lightweight, easily absorbed texture. Many reviews mention using it daily as part of their skincare routine, with the serum leaving skin feeling plump and soft. While some note it can feel slightly sticky, most praise its ability to layer well with other products. Frequent comments address the convenient larger bottle size, though a few mention the dispenser could be improved. Reviews indicate it works particularly well when applied to damp skin, and many users report being repeat purchasers. Some find it requires more product than expected for desired results.

    Small but very long lasting!

    This small bottle lasted me a few months! It's super hydrating I loved using it before my moisturizer. Perfect for people who struggle with dryness and dehydration, especially while using retinol & retinoid products that can be drying!
