POROSITY refers to the ability

of the skin or a material to absorb liquids or other substances.

For example, when creating skincare products

like face masks or moisturizers,

understanding the

porosity of different ingredients

can help in formulating products

that effectively penetrate the scalp and

provide desired benefits.

Porosity can also be relevant when

dealing with materials like

fabrics headwear, and hair shaft,

as it affects how well they can hold and

release liquids or chemicals.
