Cosmetics Formulation Development

Pep-Coll 5g 4.9% Ethoxydiglycol 3g 2.9% Acetyl Hexapeptide-8 10g 9.7% Galactomyces Ferment Filtrate 55g 53.4% Vitamin B3, Niacinamide 10g 9.7% Repair Activator 20g 19.4% All ingredients are in the form of water. Can they be mixed together and applied on the face? There will be two ingredients that must be mixed in the final step. Pep-Coll and Acetyl Hexapeptide-8 Which of these two has to be mixed in the end? I'm disturbed. Suitable for newbies to mix

It will look like a slap. You can mix whichever last step first. because it will dissolve into a single mass in the end

Thank you very much. I will be ordering the ingredients.
