This post will be reviewing The Ordinary Amino Acids + B5.

In one of my previous posts, I shared how I have successfully transitioned from my winter skincare routine to my spring skincare routine. So far, that has been going well. I haven’t exactly been back to my regular AM and PM routine but at least I’ve been consistent in my daily routine. Unfortunately, a couple of days into my new routine, I ran out of sheet masks. Of course, I ordered a new batch immediately. But that will take a couple of weeks to arrive. I order them for cheap from AliExpress. In the meantime, I needed to find a lightweight hydrating serum to use until my sheet masks arrive.

So, I went through my skincare stash and I remembered buying The Ordinary Amino Acids. This was during the time I wanted to try out all their hydrators. So far, I have including The Ordinary Hyaluronic Acid, The Ordinary Natural Moisturising Factors, The Ordinary Plant-Derived Squalane and The Ordinary Marine Hyaluronics. These products are easily the best offerings from The Ordinary for dry skin.

I’m back to using Amino Acids for about a week now after a hiatus and I’m ready to talk about it.

Pin this first!

First Impressions of The Ordinary Amino Acids

  • Product Promise

According to Deciem,

This concentrated solution includes Amino Acids and Amino Acid derivatives creating a combined total concentration of 17% (by weight). This resembles the composition of Amino Acids found in the skin’s own Natural Moisturising Factors and provides enhanced barrier support, elasticity, osmotic balance and desquamation. The formulation also includes a 5% (by weight) concentration of D-Panthenol which is a pro-vitamin of Vitamin B5 to provide surface and below-surface hydration while aiding in skin repair and anti-irritant functions.

Amino Acids + B5 offers non-greasy hydration support for the maintenance of healthy, functioning skin. It may cause a temporary tingling sensation upon application. If desired, the formula can be mixed with other serums or creams upon application to reduce its strength. 

  • Overview

Like I mentioned earlier, this is an incredibly lightweight hydrating serum that is perfect for everyday use. It’s especially great for people that don’t have access to Korean Skincare for hydration but just want something from The Ordinary. Initially, just like the Marine Hyaluronics, I was disappointed by the consistency of the serum. But after layering so many products this past winter, I’ve found a new appreciation for lightweight serums during the Spring and Summer.

  • Size & Packaging

30ml amber pipette bottle.


  • Price

£5.90. It can’t get any better than that!

  • Ingredient List

I’m really clueless about chemistry hence I don’t understand most of the ingredient list asides water. But I trust Deciem to not have included anything shady.

  • Fragrance

It’s pretty much fragrance-free as far as I can tell. This makes it so suitable for sensitive skin.

  • Directions

We are directed to;

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.

  • What I do

I do exactly that except that I use it mostly in the PM for my simplified routine. I use it after cleansing with Micellar Water to hydrate my skin before my moisturiser and Rosehip seed oil.

  • How it worked?

So far, I’ve enjoyed it, to be honest. Even though, I’ve had to layer it a few times to get the hydration level that works for my skin. Asides from that, it’s not too bad. As I mentioned earlier, this is a perfect hydrating serum for the spring. Plus if you decide to layer it with actives such as AHA, BHA, Retinol or Vitamin C, I honestly doubt there will be a conflict. Although, it’s better to patch test first. But I doubt it. As for the tingling sensation that is to be expected after application, I didn’t really notice it.

The Ordinary Amino Acids vs Marine Hyaluronics

You know, a few days using The Ordinary Amino Acids, I decided that I was gonna repurchase and alternate between the two. In terms of difference, there isn’t that much. They are both lightweight hydrating serums that work during the warm seasons. You can decide to use them together or separately if you wish. There’s no such thing as too much hydration. Just remember that most times, one layer isn’t enough. You need to apply it a few more times to get that Korean style level of hydration.


The Ordinary Amino Acids is great for hydration. It cheap, readily available and will keep your skin hydrated. Just remember that you might find it inefficient during the autumn and winter. So, make sure you swap it for heavier serums or humectants like The Ordinary Hyaluronic Acid.
