This is well packaged and easy to use. The serum absorbs into skin well. Haven't noticed any improvement in skin tone.

Good serum, lightweight but given the skin moisture enough. BF is the best deal of the year.

Hydrates, provides protection - you simply can’t go wrong with Zelens

I wanted a new hyaluronic acid serum for the cooler months and my usual go-to (Pestle and Mortar) was sold out, so I thought I'd give this one a go. I am not disappointed. The formulation feels refined and elegant, and it goes on like a dream. It sinks in nicely and doesn't leave a tacky residue. It plays nicely with other products, and has left my skin hydrated and plumped up. I took a star off because I think too much of the price goes on packaging, and while a heavy bottle is nice and luxe I'd rather the attention went on the product. (For the record I'm Caucasian, female, perimenopausal, and my skin is normal-to-combination.)
