Doesn't Set Well

After using a few bottles, I noticed that some droppers make a squeaking noise when you pull them out or push them in, while others don't.

It glides on smoothly and absorbs quickly with a refreshing feel.
Perfect for those rushed mornings when you need to speedily apply your base before makeup.
Plus, it didn't cause any blemishes!

히알셀 하이드라 세럼

I heard somewhere that it works great when applied together with microneedle patches.

No complaints about the product itself! However, you should aim to buy it on sale as the regular price of 25,000 won for one bottle seems a bit steep.

This is my first time trying a serum that feels like a hyaluronic acid ampoule, and it's absolutely amazing! It's incredibly hydrating and gives me a sensation of my skin being deeply moisturized. The best part is that it absorbs smoothly without any pilling!

I felt like one application didn't give that bouncy or firm feeling, so I applied it 2-3 times with intervals. My skin is super sensitive and usually gets red and bumpy with products that don't suit me, but even with multiple layers, I didn't have any issues. In fact, it works really well when I apply it and then spritz on some mist.

It doesn't have that rich, bouncy texture. It's more like... it lacks that plump feeling. As someone with large pores, I didn't expect it to help with that, but it did seem to provide good hydration. However, it feels like the moisture evaporates quickly, so I recommend applying it multiple times.

I've been using this since early 2025, and I'm halfway through my second bottle. It seems to work well with makeup and doesn't feel sticky. My skin barrier was really damaged, so most products would pill, but this one layers well without pilling. I liked that it came in a generous amount, and it felt refreshing when applied with a mist. It didn't cause any blemishes, so I've been using it consistently.

I don't have any major complaints. It's fragrance-free and feels refreshing, which is exactly what I like.

Perfect for combination dehydrated skin that's super sensitive and prone to flare-ups. It hydrates without irritation. No pilling, so it's great to use before makeup too.

Here's a tip for an aloe mask: mix aloe gel with this hydrating serum in a 3:1 ratio. I find it boosts hydration and the effects last longer!

While there's nothing particularly disappointing, I wish this excellent product had more promotion. It would also be great to see more frequent summer discounts.

I've used up an entire bottle. Got it at a great price during a buy-one-get-one-free deal. It's a shame this isn't as well-known as other famous hydrating serums. I loved that it's gentle, replenishes moisture well, and absorbs quickly without leaving my skin feeling dry. It was a solid, reliable product that I used without any issues.

It works well with other BioHealBo products and is great for adding hydration to any skincare routine without feeling heavy.

I can't really tell what's good about it. Maybe I need to use it more to find out?

BioHealBo has many lifting and collagen lines, but this one is perfect for the hydration step. The lineup is quite useful. I've been wanting to try the resurrection plant extract, though I'm not sure about its effects yet.

Compared to other hyaluronic acid serums, I can't say it has any major advantages. It's just an average product.

I bought this product because it contains low molecular weight hyaluronic acid, and it's definitely hydrating and not bad for sensitive skin. While it doesn't absorb super quickly, I recommend thoroughly massaging it in with your hands before moving on to the next step in your skincare routine!

Personally, I'd recommend using a small amount in the morning and applying it generously at night for best results.

Given how quickly it absorbs, a larger size would be nice.

It's packed with hydration, but the texture doesn't run off your skin. Instead, it slowly glides when applied, giving you time to work it in. A little goes a long way - it absorbs quickly with a small amount, while using a full dropper provides a richer feel without being dry. It's a great base product for those with dry skin, even in summer. After using it at night, you wake up to moisturized skin without any greasiness. The best part? No stickiness on application, which is its biggest advantage. The nano hyaluronic acid absorbs rapidly without any tacky feeling, leaving the skin comfortable. Even with a small amount, you can feel a cooling sensation and your skin becoming more supple. Its strength lies in quick absorption without leaving an oily residue. While experiences may vary, it didn't cause any blemishes even on my super sensitive skin, which I really appreciated.

When I layer this product twice, sometimes it feels slightly insufficient after a while (for example, when my skin gets particularly dry during my menstrual cycle!). However, mixing it with Sidmool's Panthenol Ampoule makes it absolutely perfect. I love it so much!

This product really fills in deep dryness! Looking at the ingredient list, you can see a balanced mix of high, medium, and low molecular weight hyaluronic acid. Usually, hyaluronic acid serums often have a lot of high molecular weight and a tiny bit of low molecular weight, with no medium weight at all. But this product seems to have a nice balance of all three, which is why I decided to try it. I experienced zero blemishes or irritation, and when I layer this product twice, it provides excellent deep hydration! The price is also very reasonable, so I'm planning to stick with this one~

Use it up quickly... It's moisturizing, but it feels like the hydration is just sitting on the surface of the skin?

I love how moisturizing it is. Perfect for winter use. It feels like it really locks in the hydration.

The runny texture requires quick application skills to prevent it from dripping.

It feels like my skin is getting a rapid hydration boost. As someone with oily skin, I often find heavy creams overwhelming, but this one absorbs well and leaves a clean finish.

The consistency is quite runny, which allows for quick absorption, but I found that a single application wasn't enough to combat dryness. While thicker formulas tend to provide better hydration, this product does feel less heavy and applies with a fresh, lightweight feel. So it seems to have its pros and cons.

I've tried hyaluronic acid serums from various brands as they're great for a light application before makeup, and I noticed Biohealbo has one too. The texture is similar to others, but it's a bit thinner and less slippery. Usually, these serums leave a sticky feeling right after application, so I'd either layer a cream on top or wait for it to absorb before applying makeup. However, this product's residue disappears quickly, which I really appreciate.
