![]() He is worried about it being too white, since it has a higher percentage of zinc oxide. My dad also thinks that EltaMD UV Physical Tinted Facial Sunscreen is a more robust formula, so he would pick it over CoTZ. CoTZ Face Natural Skin Tone SPF 40, on the other hand, uses polymers like a bunch of methicones and dimethicones, along with alumina, like Australian Gold Tinted Face Sunscreen. My dad is intrigued by EltaMD UV Physical Tinted Facial Sunscreen because it uses alumina (aluminum oxide) and sodium hydroxide instead of polymers (like silicones in the CoTZ sunscreen) to thicken its base formula. ![]() Most of skin care products use polymer to thicken(stabilize)the base formula, but Product 1 uses Alumina (Aluminum Oxide) and Sodium Hydroxide to dissolve in and react with acids in water to achieve the desired viscosity for the base. I prefer Product 1 over Product 2, Zinc Oxide is the most skin friendly and effective sunscreen, however, since both actives are white in color, I don’t know when applied, is it too whitesh for you or it’s acceptable? Formulation and particle sizes of raw materials may impact the color of residue.
