Hyaluronic Acid 2% + B5

A hydration support formula with ultra-pure, vegan hyaluronic acid

The molecular size of HA determines its depth of delivery in the skin. This formulation combines low-, medium- and high-molecular weight HA, as well as a next-generation HA crosspolymer at a combined concentration of 2% for multi-depth hydration in a water-based formula. This system is supported with the addition of Vitamin B5 which also enhances surface hydration. 

Note: Hyaluronic Acid is found in the skin naturally but its natural function within the skin is not hydration. Many products have used HA to claim hydration benefits, but HA is too large of a molecule to penetrate the skin and instead sits on the surface and can draw moisture out of the skin making the surface feel soft and hydrated temporarily, while making you feel like you need more HA after the product is rinsed. This formula uses three forms of HA with varying molecular weights, as well as an HA crosspolymer, to offer multi-depth hydration and visible plumping without drawing water out of the skin solely to improve temporary surface hydration
Apply a few drops to face AM and PM before creams. If irritation occurs, cease use and consult a physician. Use only as directed on unbroken skin. Patch testing prior to use is advised. Keep out of reach of children. See how to combine multiple formulations from The Ordinary in a single regimen

Patch tests are an easy way to help predict if you may experience a negative initial reaction to a new product. It is recommended to perform a patch test before incorporating any new product into your regimen. We have outlined a general method for conducting your own patch test below based on the type of product.

  • Apply a small amount of the product onto a clean area of skin on the upper forearm.
  • Keep the area dry.
  • If the product has a specified duration of use, rinse off after this time has elapsed. Otherwise rinse off after 24 hours.
  • If any redness, burning, itching, blistering or irritation is observed at any time throughout the test, do not use the product.

Rated 2 out of 5 by from Meh.... Come out of the dropper very thick & feels very tacky on my dry skin. Even after allowing considerable time for it to dry. Did not feel as light as other HA I've use in past.

Rated 5 out of 5 by from The hydration I needed! I have been using ordinary products for a year now and I couldn't be more satisfied! Hyaluronic Acid has been in my everyday morning routine for almost a year and I have to say that the results are amazing! I live in Cyprus, a country with a lot of sun and my skin is often tight after long day but Hyaluronic Acid has been my remedy as it protects my skin and keeps it hydrated!

Rated 3 out of 5 by from Doesn't do very much I've had this serum for over a month now, but I feel very sad to say that it doesn't do much for me! I have terribly dry skin, so after reading the rave reviews I thought this would be a gamechanger, but unfortunately I still get dry patches. The consistency is alright - it almost feels like patting water on your face, but then it dries out without making my skin glowy or plump.

Rated 5 out of 5 by from Wonderful! I started using the Acid Hyaluronic from Deciem 3 months ago and will definitely buy another one. I used to have very dry skin and because it was too dry my skin would produce oil to compensate. This product hydrates so well that it doesn't hurt anymore, less oil production and no more dead skin. I also used to have large pores and this product made my skin soooo smooth, they didn't disappear but they definitely reduced. I recommend 100%!

Rated 5 out of 5 by from The best product I've ever used! I suffer with dry, flaky skin on my nose and between my eyebrows. This is the only product I have found that actually works for me and gives me instant results. I was amazed by how quickly it worked and will never be without it! I only started with a simple kit and have found this paired with the moisturiser has given me the most amazing results. It feels a little sticky when soaking in and makes your skin feel slightly tighter but this only lasts for about 30 seconds for me. I then apply moisturiser and my skin feels super soft and amazing!

Rated 2 out of 5 by from Not efficient This product does not help to moisturise my skin. I bought the 60ml bottle based on the high rating. Have been using it for 2-3 weeks together with Niacinamide 10% + Zinc 1%. I do not see any improvement and really doubt about theirs benefits as claimed. Instead, both of them leave pilling spots so I could not use either the product during AM as they won't blend with other moisturiser nor sunscreen cream, and leave the patchy marks on over the faces. Then I used them at night, but unfortunately, the pilling pieces drops into my eyes and caused eyes irritation/itchiness. Very disappointed.

Rated 2 out of 5 by from Not as effective as other Hyaluronic Acid products I bought this as I had used a face lotion with hyaluronic acid in it in the past, and loved how plump and glowing it made my skin. However, when I apply this during my morning regimen (spritz of rosewater, HA, aloe-based SPF 15) it does not have this effect. It doesn't seem to do anything. My face is just as hydrated if I skip it. There is no glow. It doesn't seem to plump at all. I've also combined it with my lotions for daytime or nighttime and that also does not seem to do anything.
