Let me take you back to 2019, I’ve just purchased The Ordinary HA 2% + B5. My first serum. My first acid. This my friends, is where it all began.

I don’t think I fully understood what a serum was, yet alone this marvellous, magical thing called “hyaluronic acid”. Although it didn’t take me quite as long to figure it out as it did to be able to pronounce it (hi-la-yoor-what?).

The rise of hyaluronic acid broke the mould for us all to start acquainting ourselves with serums and acids alike. Team this up with everyone’s OG go-to brand The Ordinary, this exact serum was (and still is) an absolute cult product.

HA is used to add hydration to your skin and lock in moisture. A variation of it can be found in the dermis (the thicker layer of your skin), as a cellular lipid that retains water, giving your skin bounce and texture. Like many things, your skin produces less and less of this as you age, so dropping in a serum which contains HA can really help keeping skin looking youthful and hydrated.

The formula uses different molecular weights so the serum can penetrate through the skin and work its magic. This stops it from sitting on top of the skin and drawing out the moisture, which only provides temporary softness rather than achieving long term results. The vitamin B5 is added as The Ordinary claim it enhances surface hydration.

You can use the AM or PM, apply to cleansed and toned skin before moisturisers and oils. Many reviewers state this works best patted into damp skin.

The Ordinary HA serum: Products


  • As with most products from The Ordinary, you will struggle to beat the price. This is perfect for beginners and anyone wanting to test-drive hyaluronic acid for the first time but don’t want the eye-watering costs of an expensive serum.

  • I was disappointed with the results. After so many incredible reviews and recommendations, I was expecting to see more of a difference to my skin than I did.

  • The texture wasn’t for me. Although not as bad as their salicylic acid, this still left my skin a little tacky and doesn’t work well if you try to rub it in.

Did I like it? Not particularly.

Price? £5.90 for 30ml

Would I repurchase? No. I’m glad I tried it, and there are many happy customers so I would urge you to give it a go if you’re looking for a first time HA serum, but I personally didn’t see the results to justify repurchasing.
