Science & Benefits
Excipients qs. (quantum satis) is a pharmaceutical term indicating the amount of base ingredients needed to bring the total formula to 100%. In skincare, these are typically inert substances like purified water, pH adjusters, or stabilizers. While they carry a 'Good' rating because they are functional and generally non-reactive, this label acts as a 'black box' for the consumer, as the exact identity of the vehicle components is not specified. For most acne-prone users, this poses no risk, but for those with extreme sensitivities to specific undisclosed solvents, it represents a lack of ingredient transparency.
