I tried googling it but the directions were very vague
If I’m making a 500g lotion I will use 20g HQ and 80g witch hazel and once dissolved , add the serum to jergens lotion. Idk why but any other lotion causes it to seperate and become lumpy . Hope this helps!
I want to know that too! Its so hard to dissolve hydroquinone powder!I came across some HQ powder but I have no idea how to dissolve it though, can anyone help me? I plan on dissolving it and adding it to some cerave lotion.
