What the gurus are saying

The sealed pump and pure-hyaluronic formula with no scent or other additives earn consistent praise, especially from those using it for microneedling, the pump design keeps oxygen out and prevents contamination from repeated dipping. Reviewers also highlight the value, at around $25 for a large container. One thing to keep in mind: both have struggled to find it in stock.

"I normally love this hyaluronic acid, the Costa Baja. I like it because it comes in a big pump. I'm not sure if it's back in stock, it was sold out for a long time, so right now I'm using something else instead."

"I don't have any preference on the type of hyaluronic acid as long as it's unscented. You don't want anything else in it, just pure hyaluronic acid."

While we often obsess over facial skincare, our HANDS are usually the first place to betray our age

"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. All right? Which when we're micro needling, we don't want other things in the bottle. We want like 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 the Costa Baja just because it's cheap and it comes in a big pump thing. You want just a pure hyaluronic acid, that's all you want. You don't want any fragrance, you don't want anything weird in it, just hyaluronic acid because that occurs naturally in our body."

"I like this 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'm not a brand ambassador for this but I like it 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 just a Costa Baja hyaluronic acid, there's nothing else in this, no scent, no nothing. 100% pure."

"I'm using a hyaluronic acid, it's 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. I can do a microcurrent treatment and 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."

"I'm using a Costa Baja hyaluronic acid you can use any sort of hyaluronic acid as long as this is just my recommendation and I've been doing this a long time you guys no scent at all so zero scent that's going to increase your your likelihood of having irritation and irritation is good because that's what we're actually doing but there is a part where it's like that is not going to be um that's going to cause more harm than good so I'm starting with a little bit of this hyaluronic acid."

"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."

Confused about which at-home skincare gadgets actually work?

"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."

"This is my favorite hyaluronic acid for micro needling. I love this by Costa Baja because it's in a pump, so no oxygen gets to it and you're not dipping something in and contaminating it every time like you see with a lot of these products. That said, it's out of stock and I can't find it anywhere, so I've had to switch to something else."

"Normally I like this hyaluronic acid by Costa Baja, but I cannot find it right now because it is out of stock. I like it because it comes in a pump, so no oxygen gets in and I am not contaminating the dropper by dragging it across my skin. I only use this specific hyaluronic acid for microneedling, and I'm waiting for it to come back in stock."

"My favorite use for it used to be mixing two of these in with the Costa Baja Hyaluronic Acid Serum and using this on my body right after I got out of the shower. I use these on my body for firming and things like that and hydration. I can tell a difference when I don't use a little bit of copper peptides in my body moisturizer. My skin gets rougher. It gets more flaky. It's more easily irritated and itchy and things like that. What I liked about the Costa Baja was that there's three ingredients in this. So it made it pretty easy to mix in and not play scientist because when you start mixing in with products that have a lot of other ingredients, you start to become a scientist and it's not necessarily a good thing. It's more simple ingredients."

"I buy the Costa Baja hyaluronic serum, it's not terribly expensive, and it's got I think three ingredients in it. I mix copper peptides raw into it and I make my own little copper peptide serum. Otherwise a giant bottle of copper peptide serum would be much much more expensive. I think this cost between 20 and 25 dollars depending on where you get it. It used to be on Yes Style, now this brand doesn't ship to the US anymore so I found it on iHerb."

"I've got my Costa Baja hyaluronic acid, which I'm mourning because I cannot find this brand anywhere. And the brand's website doesn't really have any information or anything anymore. So, I have no idea what's going on, but I used to mix this with my copper peptides and then use it on my body after coming out of the shower."

"I've got the Costa Baja Hyaluronic Acid Serum in a giant tub that is 8 oz and typically on its own is plain I wouldn't be like totally excited about it but I mix in my copper peptides and it's perfect for it so I already have my backup ready to go because I'll probably finish this one tonight. It does a really nice job and you can use this on your face body or wherever. This form is just super simple water, hexanediol and then sodium hyaluronic so it's super simple product that makes mixing it really easy. I think this tub is 20 bucks not on sale and it lasts me I don't know six weeks or so because a little bit of it goes a long way so I think that one is worth checking out."
