I bought this during lock down and I am really pleased with it wrinkles not as noticeable but dries my skin so only use at night found not as many creases on my face when I wake up.

It's not the first time I bought Hyaluronic acid serum, at first I just thought it was a random fault. But after buying my second bottle with some time apart as the product does last some time which is good... BUT shortly after a few uses the cap doesn't tighten back up properly. And I was gentle with it too, especially the second time around. I think it is down to the flimsy plastic cap. What happens is I try to tighten it up, gently like you would do normally with these sort of products & the cap just undoes itself. Because of this I cannot actually take this serum on overnight travel as the product would just leak everywhere. Also as the cap does not tighten properly that must also mean more oxygen gets to the product then it should, which can't be good. I can say with all the confidence that I will never buy this product or any other L'Oréal products in similar packaging ever again! And no one else should! At least not until the problem is fixed!
