Science
Mechanism of Action
Acetoin functions principally as a fragrance ingredient and masking agent. It imparts a pleasant, often sweet, odor to formulations, thereby improving their sensory appeal. It also effectively conceals or diminishes unwanted scents from other components, ensuring a more agreeable user experience. It does not have a direct mechanism of action on skin physiology.
