After several weeks using La Roche-Posay Hyalu B5 Serum, I have noticed a big difference in the hydration and appearance of my skin. Its formula with pure hyaluronic acid, vitamin B5 and madecassoside leaves the skin visibly softer, firmer and more filling from the first applications.
I love that it is light, oil-free and suitable for sensitive skin, as it is rapidly absorbed without leaving a sticky feeling or causing irritation. My skin looks cooler, brighter and the fine lines look less marked.
In addition, a small amount yields a lot, so the bottle lasts a long time. The quality of La Roche-Posay is really noticeable in the results.

I bought this serum because I needed extra hydration, especially with my busy schedule and long work shifts.
The texture is lightweight but very hydrating. It absorbs quickly and leaves my skin feeling soft and smooth without being greasy. I use it before my moisturizer, and it layers well with other products.
I’ve noticed my skin looks more hydrated and feels more comfortable, especially on days when it feels dry or tired.
Pros: very hydrating, lightweight, smooth texture, good for daily use
Cons: a bit pricey for the size
Overall, this is a great serum if you’re looking to improve hydration and keep your skin looking healthy.

I’ve been using this for a year, and I can really see a difference in how "bouncy" my skin looks. It absorbs quickly and doesn't leave a sticky residue. It's become a staple in my morning routine for that extra glow. People tell me I even look younger for my age. Best hyaluronic acid serum I’ve tried so far.

I’ve been using the La Roche-Posay Hyalu B5 Pure Hyaluronic Acid Serum regularly, and it’s one of the most reliable hydrating serums I’ve tried. The lightweight, gel like texture absorbs quickly without feeling sticky or heavy , this is a must for me because one thing i cant stand is when a product leaves me feeling grimy, and right after applying I can feel a noticeable boost of moisture my skin looks fresher and more supple almost immediately. The formula uses pure hyaluronic acid to draw in moisture and vitamin B5 to help support the skin’s moisture barrier, which over time makes my skin feel softer, plumper, and less dry or tight.
It layers easily under moisturizer, sunscreen, and makeup without pilling, and it works well with both morning and evening routines. I’ve noticed that with consistent use my skin feels more elastic and balanced, especially in areas that tend to get dry. It’s gentle enough for most skin types, including sensitive skin, although if you’re extremely sensitive to fragrance you might notice the scent more than in unscented serums.
It’s a bit pricier than basic drugstore hyaluronic acid gels, but the quality feels solid and the hydration is real you can see and feel the difference. If you want a hydration boosting, everyday serum that helps skin look smoother and more plump without irritation, the La Roche-Posay Hyalu B5 Serum is a dependable choice.

If you want your skin to feel supple and so so soft get this immediately. I have tried a couple of different serums and this has got to be the best one yet.
It smells so good, and I stay touching my face for hours because it feels amazing.
I do wish it wasn’t in a dropper bottle as I prefer the pumps - but that’s personal preference. It is also a small bottle and pricey in my opinion but it will unfortunately be a staple in my routine.
I didn’t even finish my last serum and prefer this one now.

I absolutely love this serum! It absorbs quickly without feeling sticky and leaves my skin deeply hydrated and plump. After just a couple of weeks, I noticed my skin looking smoother, healthier, and more radiant. The fine lines around my eyes have softened, and my skin feels refreshed all day. Perfect for sensitive skin too — no irritation at all. This has become a staple in my skincare routine, and I highly recommend it to anyone looking for effective hydration and repair.

I have very sensitive skin and this thermal water was the first step my dermatologist added to my routine. It instantly calms redness, refreshes, and preps my skin before serum and moisturizer. It feels pure and gentle, never causes irritation, and is a product I can’t live without anymore. It may look simple, but it makes a huge difference—5 stars without hesitation.

I bought this 3 la roche posay set coz I want to lighten my face as am always expose cleaning our swimming pool everyday and florida weather made my skin darker. I dont use skincare coz im lazy and busy and has sensitive skin but I found this brand from my flight attendant friend coz her skin was amazing!!!and ddnt think twice to try bcoz of her!
- Mela b3 - to lighten my face (day and night use)
- Hyalu b5 - to hydrate my face and help with fine lines in my eyes, anti aging serum (day and night use)
- Hydraphase- for dehydrated skin and dull complexion (day and night use)
When I wrote this feedback its my 6th day using it and am so happy so far. No breakout, not affecting my skin, no stings, no weird side effects in my face, it feels really good in my face and my make up became awesome looking its not caky anymore and no more annoying lines from my foundation , thats when i found out my skin is normal to dry skin (i get caky and lines when im on foundation) and these set helps me a lot!!! Hoping to bring back my lighter face soon with mela b3!!!
About the seal and authenticity I searched about it too I was bothered of not having seal so I made a research and found this
•No, not every La Roche-Posay product is sealed some come simply in a box with no wrapping or seal.
• Yes, some items feature protective elements like QR codes or holograms for authenticity.
• Packaging styles can differ depending on the product type and region.
If you’re ever unsure, you can usually check authenticity by scanning the QR code (when present) or verifying the product through their official website or app.
Negative part, Its little pricey but so worth it!!!
