  • Highly recommend!
Size: 1.01 Fl Oz (Pack of 1)
continue to use it for a while longer as part of my facial routine. ChatGPT said: I absolutely adore this Hyaluronic Acid Serum for my skincare routine. After cleansing my face with a gentle cleanser, I apply this serum as the first step in my routine. It feels incredibly soft and gives my skin a refreshing, hydrating sensation. I’ve been using it for a couple of months, and it’s lasting much longer than I expected—a little truly goes a long way! I particularly enjoy using it for facial massages before it’s fully absorbed, as it glides smoothly over my skin. The fragrance is light and pleasant, never overwhelming. Since incorporating it into my routine, I’ve noticed a visible improvement in my skin's texture and hydration levels, thanks to the benefits of Hyaluronic Acid. I’m thrilled with the results and plan to keep it as a staple in my skincare regimen. Highly recommend! ... show more

  • New skin care
Size: 1.01 Fl Oz (Pack of 1)
I love this! It makes my skin look very glowy & not oily. But it is a little thick not very much, but over all I love it & it smells good. The only thing is that this has a fragrance which is not good for the skin.

  • Amazing skin glow
Size: 1.01 Fl Oz (Pack of 1)
This serum is the best on the market in my opinion! It is very lightweight, gives your skin the amazing glow it craves, adds moisture to your skin almost immediately. This lays perfectly under your makeup and can be used daily. It has no scent to it and I have a super sensitive nose. I also have super sensitive skin and this plus the sunscreen by this same company I have no issues using daily. It is very effective in creating your skin barrier to give you skin a smooth appearance. ... show more

  • I’m genuinely impressed with the results
Size: 1.01 Fl Oz (Pack of 1)
I’ve been using the La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum for a few weeks, and I’m genuinely impressed with the results. The combination of hyaluronic acid and vitamin B5 makes my skin feel plump and hydrated without any heaviness or greasiness. I love how lightweight the formula is, making it perfect for daily use under my moisturizer or even makeup. After consistent use, I’ve noticed that my skin looks smoother and more radiant, and fine lines around my mouth and eyes appear less pronounced. It absorbs quickly and doesn’t leave any sticky residue, which is a huge plus. The only reason I didn’t give it 5 stars is the price—while the product is excellent, it’s a bit on the expensive side for the amount you get. Nonetheless, if you’re looking for a high-quality serum that delivers noticeable hydration and anti-aging benefits, this is a fantastic choice! ... show more

  • Fantastic
Size: 1.01 Fl Oz (Pack of 1)
I have always had uneven skin on my forehead for as long as I can remember. After using this serum for only two weeks, it has smoothed out the skin and made my whole face much more consistent. I did notice some breakouts around my nose and chin, but even that cleared up much faster than a typical whitehead. This will be a repeat purchase, I’m super happy with the results. ... show more

  • A Game-Changer for Radiant Skin: La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum
Size: 1.7 Fl Oz (Pack of 1)
The media could not be loaded. As someone who is passionate about skincare, I've tried countless serums claiming to deliver hydration and youthful radiance. La Roche-Posay's Hyalu B5 Pure Hyaluronic Acid Serum stands out as a true gem among the sea of products on the market. After incorporating it into my skincare routine, I'm thrilled to share my experience and endorse this product wholeheartedly. First and foremost, let's talk about the scent. Unlike some skincare products that overwhelm with strong fragrances, the scent of this serum is subtle yet delightful. It's a refreshing experience that adds a touch of luxury to my daily skincare ritual without being overpowering or artificial. Upon application, the serum glides effortlessly onto the skin, leaving behind a silky-smooth texture. It's incredibly lightweight and absorbs quickly, which is perfect for layering under moisturizers and makeup. What truly sets it apart is its ability to provide intense hydration without any greasiness or residue. From the first use, I noticed a significant improvement in the plumpness and overall hydration of my skin. The star ingredient, hyaluronic acid, works wonders in attracting and retaining moisture, ensuring that my skin stays hydrated throughout the day. Coupled with vitamin B5, known for its soothing and reparative properties, this serum goes beyond just hydration—it actively nourishes and revitalizes the skin, leaving it looking radiant and healthy. One of the things I appreciate most about this serum is its versatility. Whether I'm dealing with dry patches in the winter or battling dullness in the summer, this serum has become my go-to solution. It's gentle enough for daily use yet potent enough to deliver noticeable results over time. Plus, it plays well with other skincare products, making it easy to incorporate into any routine. After weeks of consistent use, I can confidently say that La Roche-Posay's Hyalu B5 Pure Hyaluronic Acid Serum has become a staple in my skincare arsenal. Not only does it deliver on its promises of hydration and radiance, but it also provides a sense of indulgence and self-care with each application. If you're in search of a serum that ticks all the boxes—great smell, silky feeling on the skin, and unparalleled hydrating power—look no further than this extraordinary product. Trust me, your skin will thank you! ... show more
