The Skin Edit

Rated 5 out of 5 by from Great for my thirsty skin As I delved into the 'over 40's' category one thing I really noticed was that my skin was becoming much 'duller' and less elastic. It lost it's youthful/dewy, glow and was in desperate need of a 'drink'. I've never been one for make-up nor any sort of skincare routine for that matter but the effect of ageing was undeniable. After reading up a lot on how and what to use to get hydration back into my skin I took the plunge and committed to making more of an effort with my health and fitness and also invested in some hydrating skincare products. I have to say, it has all been worth it. This serum in particular is almoust aqueous jelly-like (similar to aloe vera) and glides on well. I apply it to my slightly damp face after toning and let it settle in (which doesn't take long) before going over with my moisturiser. I worried that all these new products on my skin would be too thick and bring me out in spots but it was so not the case. My skin must've been so thirsty it drank it up. Now my cheeks are much less papery/leathery, more supple and has that natural healthy glow that I missed. I'm also pleasantly surprised at all the lovely comments I now seem to receive about my skin since I started using these products. It's now going to be a staple in my skincare regime.

Rated 5 out of 5 by from Happy Lovely serum, quite runny though. Pipette to draw from bottle can get a bit messy. Product smells lovely, some may not like that as it’s pretty strong. Applies well and appears to work!!!!

Rated 5 out of 5 by from Super hydrating HA serum My favourite hyaluronic acid serum - takes a while to sink in but I don't mind that. Apply on a slightly damp face and it's SO hydrating, has really made a difference to my skin

Rated 3 out of 5 by from Very average- not for dry skin I don’t love this product. I have very dry skin and thought this would be lovely and Hydrating but I think it’s making my skin feel dry and sticky. Wouldn’t use again

Rated 5 out of 5 by from Fantastic I’ve been using it for one week and I can already see and feel a dramatic improvement in my skin texture and appearance. It’s now plump, luminous and pleasantly elastic. I love it its my favourite! Definitely recommend it to everyone!

Rated 5 out of 5 by from Best serum EVER I have very sensitive skin and started having a reaction to the Avene cream I was using. Am absolutely delighted to have discovered this range - love la Roche posay!! I’m allergic to nickel as well so the fact it’s certified nickel free is an added bonus. It is an amazing texture and even tho it’s for sensitive skin has a very delicate light fragrance which is such a treat for someone used to unscented plain creams! I used the cream and the eye cream in this range also and I just love them all - no skin reactions and my skin feels great really moisturised and nurtured. Would 100% recommend.

Rated 5 out of 5 by from Fantastic results I have been using this serum for a few weeks now. I am a fan of La Roche Posay products and I was looking forward to trying this serum. It’s very easy to use and a little goes a long way. I use it both morning and evening and my skin feels soft, nourished and plump afterwards. I use it on my face and neck and I’ve noticed great improvement. Price wise is great too. A fantastic serum.

Rated 5 out of 5 by from Game changer I had to throw away so many B5 products until I caught this baby. It’s even better than Skinceuticals B5! Rich in texture, a bit sticky at first but that feeling will go away if you give it one minute. Recommended to my friends and they all said it was amazing. It keeps your skin glowing, dewy. I use right after the toner step and follow with the Baume B5 which is also from LRP.
