Shereene Idriss warns against DIY hyaluronic acid serums. Ultra-low molecular weight HA under 80,000 Da can penetrate too deep and irritate sensitive skin. Homemade jars risk bacterial and mold contamination from repeated hand-dipping.
This is how easy just to make hyaluronic acid serum at home. First, you're going to need hyaluronic acid powder and distilled water. And this is why. This is asinine. Exactly why I've been saying no one should be spending 300 on a hyaluronic acid serum. But what this woman here is doing is quite smart. But. There are some buts. The hyaluronic acid that she's using is an ultra low molecular weight hyaluronic acid. It is less than 80,000 Daltons. The smaller the molecular weight of the hyaluronic acid, the deeper it goes. But that can also lead to potential inflammation and irritation, especially if you have sensitive skin. So if you are going to be overusing and abusing of this homemade serum, your skin will not be happy. Second, the size of hyaluronic acid serum that she made is also asinine. Even if you put it in the fridge, mold, bacteria can grow. Look at your food. Food does not last longer than a week after it has been consumed, especially not if you stick your food in your Tupperware. If you stick your hand in this jar over and over like she's doing, you're going to introduce bacteria onto your skin. You're going to get an infection. And last, I much prefer glycerin. Hyaluronic acid is overhyped.
