Cosmetics Formulation Development

My former daughter was already suffering from acne. When school starts, you have to wear a mask all day. I went to school one day and my acne increased by 3 pills. I would like to ask as follows. 1. Is this ingredient compatible? Rose Water 42% Willow Bark Extract 10% 4D Hyaluronic Acid 5% Laurocapram (Water Soluble) 2% Madecassoside -80 ( Centella Asiatica Extract ) Extract ใบบัวบก 1% Prebio-care (Skin Prebiotic ) 3% MOIST72™ 2% Tea Tree Oil (Water Soluble) 2% Licorice Extract ( Licochalcone A 1% ) 1% Nano Silver Solution 2% Silky Serum Base 30% 2. If you want to cut Silky Serum Base and add Rose Water is 72% for essence will make Nano Silver Solution is silk sludge? 3. Can you mix in order? What precautions must be taken?

Hello, I don't know what tool to mix. Using Silky Serum Base must be blended at sufficient speed. Hand manipulation can be difficult. This formula can be made into essence (liquid water). There is no sedimentation problem. But the packaging must be opaque, do not expose it to light, because Nano Silver Solution will have problems with light, if exposed to light, silver will precipitate.
