These soaps are typically made using a soap-making technique like the melt-and-pour method, where different colored layers are poured sequentially. The wavy sides are created by pouring the soap into a specialized mold. The shimmering effect on the top of the bar is achieved by adding mica powder, a natural mineral that provides a pearlescent luster to the soap.
The visible layers, with a lighter, slightly translucent bottom layer and an opaque, sparkly pink top, indicate that the soap contains a blend of ingredients. Many natural soaps of this type use a combination of saponified oils like coconut oil, olive oil, and shea butter to create a moisturizing and gentle bar that cleanses without stripping the skin. The specific scent and full ingredient list would depend on the maker.
