Apply a few drops to face in the AM and PM before creams. A tingling sensation can be expected after application. If the sensation is too strong to tolerate, the formula can be mixed with other creams or serums of your preference before each application to reduce the strength.

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...

Hydrates, plumps, smooths

I use a prescription retinoid nightly. I use this amino acid serum as a first step after cleansing and before application of my retold lotion. It provides a layer of protection AND improves my skin. I use this twice daily and could not be happier. I will continually repurchase and I recommend.
First step after cleansing
I use prescription retinoid nightly. I wanted a serum to moisturize my skin before application. This serum works really well. It makes my skin plumper, hydrated and smoother. It is high on my favorite serums list. I use it twice daily.
Combine with peptides
Verified Buyer

Like others who have left reviews, I think this product is really hydrating. I use it when my skin is dehydrated from drinking too much coffee or being in a cold dry environment. I first heard about b5's from a YouTube influencer who said to use it in the winter when your skin is dry. I wish I had known sooner that this product can be combined effectively with peptides. I was skipping peptides on days that I was using this at first. Combining this product with a peptide serum can improve the overall serum texture and benefit. You can also use it at night before a retinol. I find it's uncomfortable when I first put it on my skin but then the sensation goes away and the benefits are fantastic. You might want to dilute it with a bit of oil if you have sensitive skin.
The most hydrating product I've ever used
Verified Buyer
Reviewed at

I have been using this over the past 12 or so months and have repurchased multiple times. Nothing hydrates like this does (and I've tried a lot of different products from many different brands). I have combination skin and can't use face oils or squalane as both cause hectic CCs and breakouts. It hydrates exceptionally (and not just on the surface - it really feels like it works through the layers) and doesn't cause any issues whatsoever. I use this in the evenings as I find that it is slightly oily/sticky feeling (despite being water based) and does feel a bit heavier than some of my other serums, however, the oily/sticky feeling disappears relatively quickly. This product can be layered and I've never had an issue with pilling. 10/10, will forever repurchase.

This is a great hydrator for my skin. I use it twice a day and won't ever be without it. I love the price and how it keeps my skin hydrated.
