Active Cosmetic Mechanisms
ANTISTATIC
Static EliminatorReduces static electricity and flyaway hair
SCIENTIFIC ANALYSIS
// Evidence: Antistatic agents neutralize electrostatic charges through cationic surfactants (quaternary ammonium compounds like behentrimonium chloride) or conductive polymers that increase surface conductivity to dissipate charge or attract moisture. The mechanism involves forming a conductive film on fiber surfaces, neutralizing charge buildup. Particularly effective on damaged hair with raised cuticles.
HAIR CONDITIONING
Hair SoftenerImproves hair manageability, softness, and appearance
SCIENTIFIC ANALYSIS
// Evidence: Hair conditioning ingredients smooth the cuticle, reduce frizz, and add shine through cationic surfactants (behentrimonium chloride), silicones (dimethicone, amodimethicone), natural oils, and proteins. These deposit on negatively charged damaged sites, neutralizing charge, filling surface irregularities, and providing lubrication. Mechanism involves electrostatic attraction, film formation, and surface smoothing.
HUMECTANT
Moisture MagnetAttracts and retains moisture in skin and hair
SCIENTIFIC ANALYSIS
// Evidence: Humectant ingredients draw water from the environment and deeper skin layers through hygroscopic properties. Common humectants include glycerin, propylene glycol, hyaluronic acid, urea, and alpha-hydroxy acids. These contain multiple hydroxyl groups or other hydrophilic functional groups that form hydrogen bonds with water molecules. Mechanism involves attracting water to the stratum corneum, reducing transepidermal water loss, and increasing skin hydration.
SKIN CONDITIONING
Skin EnhancerMaintains skin in good condition and improves its feel
SCIENTIFIC ANALYSIS
// Evidence: Skin conditioning ingredients enhance appearance, texture, and health of skin through various mechanisms. This broad category encompasses emollients, humectants, occlusives, and other agents that improve skin feel, appearance, and function. May work by moisturizing, smoothing, softening, or protecting skin. Effects include improved tactile properties, enhanced barrier function, and better overall skin condition.
