  • substituting powder HA for liquid

    Posted by esthetician922 on May 27, 2020 at 10:21 pm

    Hi guys, 
    My formula calls for powder hyaluronic and i bought a liquid made up of the following: INCI: Sodium Hyaluronate Crosspolymer, Sodium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolyzed Sodium Hyaluronate, Pentylene Glycol, Ethylhexylglycerin, Aqua

    Should I just suck it up and buy powder or how can I use the liquid in place of it % wise?

    Maybe I am overthinking it. 

    hyaluronic is only 1% of the formula.

    You can do whatever you like! 

    Hyaluronic acid usage is mostly constrained by cost and viscosity build up depending on molecular weight. Too much can also dry and leave a powdery film or pill on the skin it seems. Some claim that it can have a “drying” effect if concentrations are too high or used in dry climates (take it with a grain of salt).

    Only by experimentation you’ll find what the best amounts to use are. Normally you want to use the least amount of a product that still gives noticeable results to keep costs low and profit margins high! 

    Worst case scenario: you spend a lot of money on a expensive and trendy raw material. 🙂

    When it comes to what is used: 1-2% hyaluronic acid (1% HMW, 0.5-1% SLMW and MMW). But this is just a guideline. The liquid version you have doesn’t specify molecular weights or concentration. If they do, calculate how much you need of that solution to achieve whatever final concentration you want.

    Thanks @letsalcido
    I figured I was overthinking it.
