I would like to know how to use Hyaluronic Acid (Japan) in the formula. For example, if you want to produce 500 grams of gel, use 1% HA in the formula, you need to dissolve 1 gram of HA in 99 grams of water first, then put the dissolved HA into it. In the formula in the amount of 5 grams (500*1% = 5), right? If not, please explain how to use it before ordering. Thank you very much.

hello

If you want to produce 500 grams of gel texture, use HA 1%.

Answer: 5 grams of HA, 495 grams of water, blend well.

Don't forget preservatives. I recommend Mild Preserved Eco 1%.
