Product Description

An intensely hydrating serum that is clinically proven to re-plump and repair skin in only 1 day.
Specifically formulated for de-hydrated skin that is showing signs of aging - loss of volume and skin elasticity with fine lines or wrinkles.
Immediately after application of this Hyaluronic Acid Serum, skin recovers bounce, suppleness and a radient complexion.
Clinically proven to improve elasticity & firmness by 24% and hydrate skin by 70% in just 4 hours.
After a month of use, 87% had more elastic and even skin and 71% agreed their wrinkles looked reduced

Hyaluronic acid effectively plumps the skin which reduces the appearance of fine lines and wrinkles, as well as improving skin hydration and texture. This formula contains two different sized molecules of Hyaluronic Acid. The larger molecule works on the surface of the skin to reduce wrinkles and re-plump the skin. The smaller molecule penetrates more deeply into the skin to increase skin volume and elasticity.

Vitamin B5 helps improve the skin's natural repairing process and helps stimulate repair of damaged skin.

Madecassoside accelerate helps stimulate collagen synthesis which gives skin its firm and elastic quality.

Hyalu B5 has been through rigorous dermatological testing to ensure it is suitable for even the most sensitive skin.
9/10 dermatologists would recommend La Roche-Posay for sensitive skin.
Recommended for use as part of the optimum anti-ageing regime as agreed by our top UK dermatologists.

Fresh re-plumping hydrating serum. For dehydrated, dull skin, showing signs of ageing. Contains Hyaluronic Acid and Vitamin B5 to repair and re-plump skin. No parabens or colourants. Suitable for even the most sensitive skin.

Directions

Use Hyalu B5 Serum every evening after cleansing, to repair and hydrate the skin overnight, followed by a Retinol night cream.

Rated 5 out of 5 by from Absolutely lovely I’ve been using the Hyalu B5 Eyes Serum for a few weeks now, and it’s quickly become a staple in my routine. The texture is lightweight but hydrating — it sinks in beautifully without feeling greasy or heavy. It instantly smooths and plumps the under-eye area, making my tired eyes look more awake. Fine lines look softer, and my concealer sits better throughout the day. The formula feels super gentle (no stinging at all), which is a big win for my sensitive eyes. 💙 Bonus: It’s fragrance-free and pairs well with my other skincare. 👁️ Verdict: Hydrating, soothing, and worth every drop!

Rated 5 out of 5 by from Excellent serum I love this serum! I have very sensitive skin but I can even use this round my eyes. It absorbs very easily and I think it definitely makes a difference to how my skin looks and feels. I’ve had lots of people asking me why I don’t look 53 - mission accomplished! I highly recommend this serum - I use it with the Roche Posay SPF 50 moisturiser, also fantastic. No problem putting on make up afterwards, no piling.

Rated 5 out of 5 by from I LOVE THIS I like using this so much because it is not sticky at all and sits beautifully on my skin. It makes my skin feel so smooth, glowy and hydrated through out the day. I have sensitive skin and let me tell you this did not disappoint me. Will definitely be re purchasing this!

Rated 4 out of 5 by from Can't find information on site How do I store it? Should it be kept in the dark? A fridge, away from sunlight? However could be me? I've given 4 stars for now and said I would recommend a friend. But, only started using today and too soon to tell. I do agree dropper could be better though.

Rated 1 out of 5 by from Heavily fragranced I’ve used a few of la Roche posay products before and enjoy the fragrance free products for my super sensitive rosacea skin. I bought this assuming the same but it has an extremely strong fragrance and irritated my skin immediately. There should be notes to say that this contains fragrance as it’s not cheap for something I could only use once! Disappointed at lack of transparency for this one.

can i use this on legs?

Asked by: Anonymous
It’s designed for facial use although I’m pretty sure you can use this anywhere,  it’s a bit expensive for leg use. Maybe a good cream would be better.

Can I use this product around the eyes too?

Asked by: Gersende
You absolutely can. It’s amazing for moisturising around the eye area and I’ve noticed a huge improvement in fine lines around a my eyes since using this. I’ve tried lots of hyaluronic acid products and this is by far the best, I wouldn’t use anything else now

Will this serum cause breakouts ?

Asked by: Anonymous
Hi, The La Roche-Posay Hyalu B5 Hyaluronic Acid Serum will not cause breakouts and in fact, may help and acne skin. La Roche-Posay as a brand work along side dermatologists to target skin problems of every kind (especially problematic skins). Hyaluronic Acid also not only helps plump skin by giving it a drink of water, but did you know it actually also helps regulate inflammation levels and helps to balance sebum production too? Hope this helps! Thanks Katie, Beauty Expert.
