Effect of Viscosity to Active Ingredients Efficiency
Hi everyone,
I have one question on my mind. Is there any article/data which gives some insight about the viscosity effect on active ingredients?
Let me explain better: So let’s think two serum formulations both of them have some active ingredients in them. One is low viscosity (like 300-400cps) and other one is really thick like (let’s say 30.000cps). In normal cases if you put them on the top of the sheet of paper the low viscosity one will go under the sheet very easily and the high viscosity one can’t wet the surface.
So my actual question is; because it won’t let the active ingredient go into the skin do very high-viscosity products make products less efficient? If we think like retinol will it oxidize till go into the skin? Or maybe never even reach to first layer epidermis?
I look forward to hearing your opinion.
