Reviews Summary
Customers say this serum absorbs quickly into the skin and provides immediate hydration. Many reviews mention its lightweight, non-sticky texture that layers well with other products. The serum leaves skin feeling plump and soft, with users particularly appreciating its gentle formula. While most find it deeply hydrating, a few note it's basic in performance. Frequent comments address its versatility in skincare routines and easy application. Some mention the packaging could be improved for better dispensing.

    Uncomplicated serum

    Love this hyaluronic acid serum. It’s just that, simple. This allows me to use other ingredients as I wish. Normally this type of serum has other ingredients in it. That does not agree with my skin but this one is great. Would prefer the packaging to be different- maybe a dropper wound be more convenient for application.
