Love this hydrating serum!
Fantastic! My skin feels and looks so hydrated! I like the smell and smooth texture. It doesn’t bother my sensitive skin or rosacea. My forehead wrinkles are much less pronounced and less noticeable. I didn’t realize it was due to dry skin. I was using expensive wrinkle creams on my forehead with no results. This has made the biggest difference. Love this product! Will keep this is my daily regiment forever! It took years off my forehead in 2 weeks! Wish I took a before photo! Because I liked this so much I tried the cleanser by the same brand, I like it. Looking forward to trying more of this brands products. Great prices too!

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!!!

Holy hydration. Plump, smooth, and sensitive-skin friendly.
I’ve been using La Roche-Posay Hyalu B5 Serum for a few weeks now and I’m honestly impressed. My skin tends to get dry and tight (especially in winter), and this serum makes my face feel immediately hydrated, soft, and noticeably plumper. The texture is lightweight and absorbs quickly without feeling greasy or sticky. It layers beautifully under moisturizer and makeup, and it hasn’t caused any irritation or breakouts (which is huge for me because my skin can be sensitive). After consistent use, my skin looks more smooth and refreshed, and some fine lines look less noticeable simply because my skin is so much more hydrated. A little goes a long way, so the bottle should last a while. Definitely a great product if you’re looking for hydration and a healthy glow. Highly recommend!

Hydrating, Soothing, and Perfect for Sensitive Skin!
La Roche-Posay Hyalu B5 Serum has been a game-changer for my skincare routine. The formula is lightweight, absorbs quickly, and leaves my skin feeling instantly hydrated and plump. I’ve noticed a visible improvement in smoothness and elasticity after using it consistently. It’s gentle enough for my sensitive skin, no irritation, redness, or breakouts at all. I love that it combines hyaluronic acid with vitamin B5 and madecassoside. The combination really helps restore moisture, soothe dryness, and give a subtle anti-aging boost. It layers beautifully under moisturizer or makeup, and the oil-free formula is perfect for daily use, even for combination or oily skin types. If you’re looking for a high-quality, effective hydrating serum that supports healthy, youthful-looking skin without harsh ingredients, this is a must-try. Reliable, soothing, and genuinely nourishing. Highly recommend!

Serum
This serum is very hydrating and lightweight. It absorbs quickly and makes my skin feel plump and refreshed. I like using it before my moisturizer because it helps lock in hydration and gives my skin a healthy glow. It works well under makeup and doesn’t cause irritation. Great option for anyone looking to boost hydration.

Very nice and refreshing
So refreshing and nice light scent it. Some things like this that I’ve used had a small or texture that I did not like but this is nice and lightweight, moisturizing, and refreshing.

Go to everyday face serum
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.

Love the product. Goes great with my other La Roche products. I notice a difference after I've cleansed and applied the serum. My skin looks brighter and less stressed/tired. I will keep using it

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.

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.
