Adding Ingredient to Pure Aloe Vera Gel Tester and Using Vitamin C Serum Testers

Question

I purchased the tester product "Pure Aloe Vera Gel" and added the following ingredients:

Whitening/Anti-Acne: Azelaic Acid (Potassium Azeloyl Diglycinate) 10%
Moisturizing: Galactomyces Ferment Filtrate 20%
Anti-Oil: MatteSilica™ (Silica) 5%
Anti-Acne: Salicylic Acid EZ™ (BHA) 5%
Anti-Oxidant: Hi-EGCG™ (Green Tea Extract) 3%
Anti-aging/Anti-Acne: Vitamin B3 (Safe-B3™) 5%
Anti-aging: Copper Peptide (GHK-Cu) 3%

I would like to know if I can add Repair Activator™ (Bifida Ferment Lysate) to this mixture myself. If so, what percentage should I add?

Also, for the testers Vitamin C E Ferulic (Lite) and stabilized vitamin c (Natural-C Glycol™) Serum, can they be used directly on the skin, or do they need to be mixed with cream first?
