What the gurus are saying

This serum's 3% hyaluronic acid concentration is unusually high, making it thick in the bottle but smooth on skin. Both gurus appreciated the hydration and ceramides for the moisture barrier, though they weren't convinced they'd repurchase, particularly if they already use other hyaluronic acid products. The fragrance-free formula includes some stabilizing alcohol, which didn't bother those who tried it.

"I just finished it up and I've been using it off and on. I actually ended up really really really liking this all the way through. It worked out really well just for hydrating the skin. I think it's a great option for a hyaluronic acid serum. It also has ceramides which are good for the moisture barrier. But one thing I have a gripe with is this particular format of serum."

"This is the hyaluronic acid 3 and I actually do really like it, it's just still ultimately a hyaluronic acid serum, so it's another product where I'll use it but I'm not sure I'll repurchase it, I already have so much hyaluronic acid. I do like that it's a fragrance free formula with some additional soothing ingredients including ceramides, and somehow hyaluronic acid at three percent, which is a high level we don't see too often."
