Expensive but effective
One of the best HA serums on the market and nice splurge when you want something French and fancy sounding. It hydrates and plumps fine lines as advertised without being heavy nor greasy. It does have a fragrance, but it is pleasant and mild. I was concerned it would irritate my very sensitive skin and rosacea, but pleasantly surprised after a month of daily use, zero problems. I use it in combination with the Double Repair moisturizer. My dermatologist has been pretty impressed with the health of my skin lately. In complete fairness, there are other HA serums on the market that are as effective, use the same ingredients and concentrations, at half to a quarter of the price (The Ordinary, for example.) YMMV

Hydrating serum that leaves skin soft and plump
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.

Sensitive, Normal to Dry Skin and this is the amazing set I bought
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!!!

Extremely hydrating
In my skin care routine, I start with cleansing, then using a toner, followed by a serum, and then a moisturizer followed by sunscreen. I am always searching for the next best thing to replace ones that I am already using. With this serum I have found my perfect one so far. This gives a lovely base line for my hydration to prep for the next moisturizer to wear. Paired with a good moisturizer this serum does wonders. I noticed that my skin stays hydrated longer than if I just used moisturizer alone. And I seen a big difference in my skins complexion. I used this everyday for two months and used it twice a day and the results are hard to argue with.

Hydrating serum that feels light and works well daily
This serum has been a really good addition to a daily skincare routine. It feels lightweight, absorbs quickly, and does not leave a greasy or heavy feeling on the skin. I like that it focuses on hydration, helping the skin feel softer, smoother, and more refreshed after use. The combination of hyaluronic acid and vitamin B5 helps improve moisture and overall skin texture. It works well for both men and women and layers easily with other products. A great option if you want a simple, effective serum for everyday hydration and skin care.

Amazing for dry skin
This is a heavenly product. I have suffered from dry skin for years. I introduced this product to my routine and can say that this has hydrated my skin and made it look healthier on a daily basis. It also does not give me milia, which I have had issues with in the past. Love it and will continue to use morning and night.

Best brand and product.
I like that it delivers noticeable moisture and plumping effects without feeling heavy or greasy. The hyaluronic acid helps draw water into the skin, which can make skin look smoother and more refreshed pretty quickly. The addition of vitamin B5 also helps soothe and support healing, so it’s often recommended for dry, irritated, or slightly compromised skin. The texture is slightly gel-like but absorbs well, layering nicely under moisturizer and makeup. It’s also fragrance-free, which is a big plus for sensitive skin users.

Great product, would purchase again
I was hesitant to buy this because of the reviews saying it was too sticky and didn't absorb well in their skin. Luckily, I decided to try it anyways, and I personally think it's great. I find it no more sticky then similar, more expensive serums I've tried and after it absorbed in after a few minutes it my skin felt smooth, soft and clean. I've had no outbreaks or reactions to this product so far, and I have very dry skin due to the cold harsh winter and find it is hydrating nicely. Also the scent was not that bad. It has a mild perfume scent that fades quickly.

Super Produkt - jedoch Verpackungsfail
Das Serum an sich ist hervorragend. Zieht schnell ein, spendet Feuchtigkeit, riecht sehr angenehm. Für Allergiker sehr gut geeignet. Jedoch ist das Handling über Amazon nun mehrmals leider wirklich schlecht gewesen. Die kleine Verpackung wurde nun insgesamt 3x in einen Umschlag gequetscht. Die Pipette war jedes Mal zerbrochen oder sogar die Flasche selbst. Da könnte das Handling deutlich besser werden. Musste es dann vor Ort kaufen, da ich es dringend für den Urlaub benötigte. Kundenservice war jedoch super bei der Reklamation.

Gran Concentrado Antiarrugas con Ácido Hialurónico
Compré este sérum de La Roche Posay después de leer varias recomendaciones sobre sus beneficios para la piel, y después de unas semanas de uso, puedo compartir una opinión honesta y constructiva. Puntos positivos: Textura y absorción: La textura es ligera, no pegajosa, y se absorbe rápidamente en la piel. Es ideal para usar tanto en la mañana como en la noche sin dejar una sensación grasosa. Ingredientes clave: Me encanta que esté enriquecido con ácido hialurónico. Mi piel se siente notablemente más hidratada y con un aspecto más fresco desde el primer uso. También contiene vitamina B5, que ayuda a calmar la piel. Resultados visibles: Después de usarlo regularmente durante 3 semanas, noto una mejora en la firmeza y un efecto de relleno en líneas finas, especialmente alrededor de los ojos y la boca. Sensibilidad: Tengo piel sensible, y este sérum no causó irritación ni brotes, algo que siempre me preocupa con productos nuevos. Precio en Amazon: El precio en Amazon es muy competitivo comparado con otras tiendas. Ofrecen una excelente relación calidad-precio, lo que hace que sea más accesible para probar un producto de esta calidad. Áreas de mejora: Tamaño del envase: Aunque el precio es competitivo, el tamaño del frasco es pequeño. Si se usara dos veces al día, podría acabarse relativamente rápido. Dosificador: El gotero funciona bien, pero sería más práctico si la botella tuviera un aplicador más preciso para evitar desperdicio, ya que el producto es valioso. Resultados a largo plazo: Aunque los resultados iniciales son prometedores, creo que necesitaré más tiempo para confirmar su impacto en arrugas más profundas. Recomendación final: Es un producto ideal para quienes buscan hidratación intensa, mejora en líneas finas y cuidado efectivo para pieles sensibles. Recomendaría complementar este sérum con una buena crema hidratante y protector solar para maximizar sus beneficios.
