Abstract
Background: In people with Fitzpatrick type IV to VI skin, dry skin can be associated with a grayish-whitish coloring, a reduction in skin shininess and even flaking in more severe cases. This condition is usually referred to as “ashy” skin. This is considered a cosmetic problem; however, it can be distressing affecting patients’ quality of life and in severe cases it can lead to further problems. There is not a wide variety of moisturizers on the market specifically designed for skin of color, which skin type usually desires a thicker, creamier moisturizer to combat dry skin symptoms.
Aims: The main goals of this study were to design moisturizing creams for skin of color and study how formulation technology affects product quality and stability.
Methods: First, a detailed review of marketed products was performed to identify key moisturizing ingredients for skin of color. After identifying the main moisturizing ingredients, other necessary ingredients were selected to formulate moisturizing creams.
Results: Multiple batches of creams were formulated with varying the processing parameters (including mixing speed, speed of
adding the water phase, using liquid vs. solid shea butter, use of water bath, and amount of oil/aqueous phase included) and the creams were tested for aesthetics, viscosity, droplet size distribution and physical stability.
Conclusions: This study showed that processing parameters and technology significantly affects the physicochemical characteristics and physical stability of moisturizing creams
