This is a rather intense serum! A few small drops go a long way. The consistency has a thickness that resembles nail polish (which I wasn't expecting), but it dries down quickly once it's rubbed/patted in. It doesn't leave a residue like oil. Don't bother using a cotton pad; just use your hands to apply. It gives a nice satiny finish and you can easily layer other products on top of it with no trouble.
In addition to having varieties of HA in there, the ingredients include cica, a very popular ingredient in k-beauty right now that's believed to soothe red/irritated skin. Aloe is listed in the ingredients, too. There is no fragrance at all; it's completely odorless, which is a plus if you have sensitive skin.
Overall, I found the product OK, not revolutionary for the current state of my skin. I have sensitive, acne-prone skin that tends to be on the drier side, and I use adapalene nightly. I'm willing to try new products to add moisture to my routine. For now, I have no plans to incorporate this product into my daily routine. I think using this when my skin is super dry and needs an extra boost will be more ideal. I have a feeling this will come in handy during the coming winter months!
