Average effective serum

5 stars out of a maximum of 5

I found the serum to be light but quite nourishing, after the first few applications I could start to see the difference in fine lines under my eyes. Not much is needed for a good application so I have quite a bit left so am hopeful of even better results over time

Fantastic Serum La Roche Posay

5 stars out of a maximum of 5

Amazing light-weight product , super fun to apply and feels very clearly superior in terms of ingredients it contains. I do feel my fine lines have reduced slightly since using and it has a great feel on skin.

La Roche-Posay Hyalu B5 Hyaluronic Acid

4 stars out of a maximum of 5

I enjoyed using this product very much. It made my skin feel firmer and it smelt absolutely fantastic. After applying to my face it did feel a little tacky for a few mins but not long. My make up went on fine afterwards too

La Roche-Posay Hyalu B5 Hyaluronic Acid

5 stars out of a maximum of 5

I felt I just had to write this review because this is such a lovely product. I’ve only been using for a few days but my skin looks and feels hydrated, soft and glowing. In fact I’ve already had comments from friends who say my skin looks amazing and you can’t ask for more than that when you’re approaching 73! Yes, the oil is quite thick, but when you have dehydrated skin, it’s like manna from heaven and maybe the people who are complaining are perhaps using too much? The dropper is a brilliant innovation too. I use the oil at night, followed by Redermic R Day (which is inappropriately named as it’s actually recommended by LRP as a night cream!) I absolutely recommend this oil to anybody

Ive been using this product for 2 weeks now. It has a faint smell thats goes away quickly. Initially its sticky but absorbs well into the skin. My skin feels soft & plumped after usage but its more noticeable after using the product with a sheet mask

The La Roche Posay Hyalu B5 serum is a lovely product. Made my skin soft and even. It did not make me skin dry or sensitive. Would definitely repurchase and I felt like I'd had a skin peel without the price tag

La Roche Posay

5 stars out of a maximum of 5

Hyalu B5 serum does exactly what it says on the box. Already after 1st use my skin felt more elastic, I love the feeling of instant hydration after applying the product. If you are looking for instant skin hydration, get yourself a bottle, you won't regret.
