Yellow, brown, yellow-brown or reddish brown skin tones are part of the same single category of foundation make-up that has always existed. Developing a strategy for extending the boundaries of shading to address a wider range of colour is necessary, especially as demographics change. Certain pigments and powders can be too white or opaque, or do not match a specific hue or undertone far Hispanic, Asian, Indian, African and Native American skin. The end result may lead to an appearance that is not perceived as natural. This article focuses on the selection of pigments and powders that will help the cosmetic formulator to create a diverse shade palette to address the needs of ethnic skin tones.

Various particle sizes and coatings are available allowing flexibility in creating a sunscreen with a high SPF, PFA, and critical wavelength. Particle size can be varied to achieve optimal results and a wider range of product forms can be created. Surface treatments can help to improve the dispersibility and stability of zinc oxide in oils, esters, and aqueous systems.
