Most loved serum. Period.
Of all the many serums I have tried from the Ordinary, and any other skincare line, this is without a doubt my favorite. I buy it again and again. I would say the best way to describe the effect this has on my fair, dry, sensitive skin is: strength. My skin feels protected, firm, bouncy, and strong ...

Still on the fence about this product!
I have to give 3 stars to this product because, after using all the content of the bottle over the course of various months, I am still confused about whether I actually liked it or not. For a bit of context: I have dry skin, which can really only take as much in terms of the amount of products I l...

I got this with the EUK 134 a few years ago, and did a patch test on my arm. I washed a large spot on my arm, then applied the Amino Acids + B5, let it dry a bit, then put the EUK over the top. In the morning, not only did I like the improved texture and hydration, much to my surprise that area was noticeably brighter and had a more even skin tone! The Amino Acids + B5 is particularly appreciated because it can be used under pretty much anything. I can not use the various versions of the Buffet, or whatever they are calling it now, because it contains some ingredients that aren't for me. Yes, it is a wee bit sticky as others have mentioned, but I have found waiting a few seconds and putting something hydrating on top takes care of that. I tend to be allergic and sensitive to things, and I don't react to this - it seems to help keep my skin calm. I don't remember now how many bottles of this I have used. It's a go to. (As an aside to deciem - please do not put squalene/squalane in this - I can not use anything with that ingredient in it. I mention it as someone suggested they might prefer it in a squalane base. I would also appreciate it if squalene/squalane could be added to your list of 'ingredients at a glance' to make it easier to avoid.)

This serum is a literal dream. It makes my skin so hydrated, plump and smooth. It sinks into my skin instantly and is so light in texture. I don't even need to use moisturiser because this does a much better job at hydrating my skin. My skin looks and feels so much nicer and make up sits much better on my skin now.
Great for very dry skin if consistent

I started with this for my skin care journey. Being 37 with fine lines and dry skin, it healed up my skin. One bottle lasts 3-4 months if using daily am and pm. Only need 3-4 drops at a time on damp skin. My skin has again started glowing like my earlier days.
I will continuet to use it!!

great price and effective
Amps Hydration Without Stickiness
My skin requires more hydration than is available in most Ordinary formulations - Buffet, Copper Peptide, etc - and I can't love anything feeling sticky on my skin. The amino acid serum helps to solve all of those issues with just a few drops.
