A catch-all term for ingredients that improve how skin looks and feels — softer, smoother, more supple. The workhorse behind most moisturizers.

Fills in the tiny cracks between skin cells to make everything feel smooth and soft. The "silky finish" ingredient.
Cleanser
Emulsifier
Forces oil and water to stay mixed instead of separating into layers. The unsung hero holding your lotion together.

Traditional Use
Lanolin, derived from sheep's wool, has been used since ancient times as a skin conditioning agent. This PEG-modified version was developed in the 20th century to make lanolin more water-soluble and easier to incorporate into modern cosmetic formulations.
