    • Hydrating serum that leaves skin soft and plump
Size: 1.01 Fl Oz (Pack of 1)
Review Image by sandra M Cardenas
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. ... show more

    • Hydrating serum that feels light and works well daily
Size: 1.01 Fl Oz (Pack of 1)
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. ... show more

    • Love this hydrating serum!
Size: 1.01 Fl Oz (Pack of 1)
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! ... show more

    • Holy hydration. Plump, smooth, and sensitive-skin friendly.
Size: 1.01 Fl Oz (Pack of 1)
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! ... show more

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. ... show more
