Hyaluronic acid.

"I like the Costa Baja. I have no affiliation with them at all. Zero. But I've been using it for years. Why? Because it's in a pump. So, you're not having to unscrew a cap to use a dropper. Every time you unscrew something, you're inviting other things into the bottle. When we're micro needling, we don't want other things in the bottle. We want pure hyaluronic acid. So, I like this because you can get it in a big container. So, it's very easy to pump this in here, but also it's airtight, so you're not getting anything inside of it. There's no scent. There's no nothing."

"I like this. This is Costa Baja. I like it for three reasons. The pump, for more purity and less exposure to stuff that will give you an infection. The fact that it's only pure hyaluronic acid, so there's no scent in it. You don't want to use anything with scent and no active ingredients. And the fact that it's in a big bottle because I use this every time I microneedle and I don't want to spend a ton of money and this is very economical to do."

"The serum I'm using is a hyaluronic acid, it's just a pure hyaluronic acid and that's what you want to look for. I like that it comes in a big tub and it's relatively affordable for what I'm using it for. I think it's less than twenty dollars, it might be twelve dollars. It's Costa Baja hyaluronic acid, there's nothing else in this, no scent, no nothing, 100 percent pure."

"I'm using a hyaluronic acid, it's a Costa Baja. I like it because it's cheap, it comes in like a bigger container, and it's not like in a little dropper. I like this as well because I don't have to wash it off of my face. The ultrasound gels are kind of thicker, the conductor gels are a little bit thicker and you have to wash them before you do anything. This I can do a microcurrent treatment, it just kind of helps the hyaluronic acid to soak in the skin a little bit, and so it's nothing that I have to wash off."

"The brand of hyaluronic acid I'm using is Costa Baja hyaluronic acid. I like it because it's cost, it's lit. I think this is like 25 bucks. It's not very expensive. It's in a huge container and it has a pump. So it's airtight. That's better for any sort of infection, right? That's better to keep the whole area clean in that this product inside here has not touched any hands or light or anything like that."

"I do like Costa Baja hyaluronic acid and I use that as a conductive gel a lot because it's cheap, you can get it in a big thing. I also use it as a slip when I'm doing micro needling. So it's a multi-purpose kind of conductive gel for me. It's just pure hyaluronic acid."
