Functions
Astringent
Tightens and contracts skin tissue, temporarily shrinking pores and reducing oiliness. That "clean, tight" feeling after toner.
Cleanser
Foaming
Fragrance
Added for scent. Can be natural or synthetic. Common irritant and allergen — one of the top reasons people react to products.
Moisturizer
Adds or helps retain water in the skin. Could work as a humectant, emollient, or occlusive depending on the ingredient.
Conditioning
A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.
Emulsifier
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.
Locks In Moisture
Traditional Use
Used by indigenous South American cultures for centuries as a natural cleanser and foaming agent due to its high saponin content. Spanish colonists adopted it for textile cleaning and subsequently for cosmetic preparations.
