We conduct photostability and free radical stability tests to assess the product’s resistance. In vivo tests, such as hydration, skin elasticity, and skin microcirculation, measure the effectiveness of the treatments. Sensory analysis evaluates organoleptic properties.
The chemical composition is analyzed using various spectroscopic and chromatographic techniques. Physicochemical properties such as viscosity, surface tension, and flash point are also determined. We also characterize texture through rheology and tribology.
