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 love this product. Keeps my face soft and supple. I would love to have it in a bigger size though, because my skin drinks it up. I use 4-6 drops to a freshly washed face. Would love to see The Ordinary come up with body moisturizers or serums that contains amino acids.
I love The Ordinary!

This serum is a must in my skincare regimen. I buy several different serums so that I can tailor it to my skin's specific needs.
holy grail - make it in a bigger size
I absolutely love this serum - It's the most underrated The Ordinary product,IMO. Because of its watery consistency, it's perfect to layer with your current skincare,specially during warmer months when you can get oilier. At night I use this serum in combination with my moisturizer; during the day,I use it with a hydrating toner. I sometimes use TO's hyaluronic acid serum,but the consistency is not my favorite; I keep coming back to this one.
No idea what it's doing but DON'T STOP
I forget how I even ended up buying this. I use it before the hyaluronic acid which is great in its own right. Adding this has almost immediately changed how my skin feels, holds moisture, and reacts to the world around me. I think I have combination skin but it's really just dry and aging (whatever that means). This (while VERY runny) absorbs very well into my skin. I see less texture issues (dry, patchy, rough etc) and a reduction of fine lines. I use it daily with an arbitrary Ordinary system. For the effect and price, this was an absolute win and a surprise find.

How do you layer this if we use multiple serums? How does it pair with Glycolic acid creams, retinol, Vitamin C and hyaluronic acids?
- Asked by Judy
- Official Answer By The Ordinary - Brand EngageHi there! Amino Acids + B5 has no conflicts and can be applied after cleansing and Glycolic Acid 7% Exfoliating Toner. We recommend applying based on thinnest to thickest consistency. If using serums with a similar consistency, feel free to layer based on order of concern.
