"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 forgot is I have a gripe with 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. That's probably what makes it a little goopy in the bottle, though it doesn't feel goopy on the skin, maybe because they included some denatured alcohol, which I personally don't mind when it's formulated into a product with care."
