These are the hyaluronic acid serums that I’ve tried that have a pH level below 6.0 (in alphabetical order by brand). I’ve also included a link to my review, where applicable.
Please note that I use pH strips and they aren’t a perfect science so the pH levels noted below are estimates only. There is also some variation between batches of products and a manufacturer may have made changes to their formula since I tested.
The majority of the products listed below are also silicone-free and sulfate-free.
