  Pros

  I bought this to replenish moisture since my face was feeling dry. It applies smoothly and seems to absorb well into the skin. The gentle ingredients make it comfortable and easy to use regularly.

  Cons

  COSRX products generally tend to feel a bit sticky when applied to the skin.

  Tip

  For those with oily skin, it's probably best not to apply too thick a layer.

  Pros

  With 3% hyaluronic acid, it really locks in deep hydration

  Cons

  The strong sour smell and sticky texture are quite noticeable. I guess it's because of the high hyaluronic acid content

  Pros

  I've been using this for about two weeks, and it seems like a great product when used correctly. It provides excellent hydration and definitely helps combat dryness when applied.

  Cons

  Probably because of the hyaluronic acid, it feels a bit more uncomfortable if it gets into your eyes.

  I tried this for the first time, and it definitely seems to have better hydration than other regular serums. I'm really enjoying using it.

  Cons

  There's nothing particularly disappointing about it. If I had to nitpick, maybe the price...?

  - Snagged this as a welcome deal for just $3! - I'm slathering it on generously whenever my skin feels parched, without any worries!

  Cons

  - It doesn't seem to pack as much of a hydration punch as I was hoping for.

  Tip

  Grabbed it for just $3 with the welcome deal!

  Pros

  I was searching for a product to combat winter skin dryness and bought this out of curiosity due to its great price. The ingredients were also reassuring. It's a serum with quite a thick consistency that glides on smoothly. As soon as you apply it, your skin starts to glow! The tight, dry feeling on my face has significantly diminished. I'm very satisfied!

  Cons

  The product is good, but when I tried to add it to my cart again, I couldn't find the product information...

  Tip

  You can feel the wrinkles smoothing out, so apply it by gently pressing in the opposite direction of your skin's natural folds.

  Pros

  After applying it before bed, I definitely noticed my skin felt more moisturized the next morning. I'll need to use it a few more times, but I'm hoping it will help reduce my skin's dryness.

  Cons

  You need to apply quite a generous amount. If you only use a little, you won't see any noticeable difference.

  Pros

  It's definitely hydrating. I've tried many ampoules, but when I use this product after applying a booster serum, it seems to combat deep dryness much more effectively. I bought it for $3 during a promotion, and it's a great value for money.

  Cons

  I can't think of any particular drawbacks, but I wish it had an extra lid for the container.

  Pros

  It's absolutely perfect for this time of year. With winter being so dry, I apply two layers before bed, and when I wake up in the morning, my skin feels amazing.

  Cons

  The price is quite steep compared to the amount you get. Unless it's on sale, it's hard to justify the purchase.

  Tip

  It works wonders when applied in layers before using a sheet mask.

  Pros

  This product provides instant hydration to the skin, making it particularly effective for dry skin types. The highly concentrated hyaluronic acid penetrates deeply, keeping the skin moisturized. A major plus is its quick absorption without any sticky residue. Upon application, you'll feel an immediate boost in hydration. With consistent use, I noticed improvements in skin elasticity and moisture retention. It's gentle enough for sensitive skin, making it suitable for various skin types. The powerful hydrating properties make it especially useful for preventing winter dryness and improving skin texture.

  Cons

  The price point might be on the higher side for some, and the lack of fragrance could be a drawback for those who prefer scented products. However, this ampoule focuses on delivering hydration and moisture, making it a solid recommendation for those with dry skin.

  Tip

  Apply after toner: For maximum absorption, use the ampoule right after cleansing and toning while your skin is still damp. This allows the product to penetrate more deeply, prolonging the moisturizing effect. Nighttime intensive care: Using it at night allows for better absorption as your skin regenerates during sleep. This maximizes the hydrating effects, especially in dry winter conditions. Apply generously before bed and layer with a cream for extra moisture. Mix with other products: This hyaluronic acid ampoule pairs well with other moisturizing products. Try mixing it with a nourishing cream or oil to simultaneously boost hydration and nutrition. A drop of ampoule mixed with your favorite cream or oil can provide richer benefits. Refrigerate for added benefits: Keeping the ampoule cool can enhance its soothing properties. Store it in the fridge and apply to redness or irritated areas for an immediate cooling and calming effect. Don't forget neck and décolletage: Extend the use beyond your face to your neck and décolletage for softer, more supple skin. Regular care of these areas helps maintain healthier, smoother skin overall.
