// Evidence: Antimicrobial agents possess bactericidal, bacteriostatic, fungicidal, or fungistatic properties through disrupting cell membrane integrity, inhibiting protein synthesis, interfering with metabolic pathways, or damaging DNA/RNA. Common antimicrobials include quaternary ammonium compounds, alcohols, chlorhexidine, triclosan, and essential oils. Efficacy depends on concentration, pH, contact time, and microbial load.

// Evidence: Antioxidants prevent or delay oxidation by donating electrons to free radicals, chelating pro-oxidant metals, or regenerating other antioxidants. Mechanisms include direct radical scavenging (vitamin E, vitamin C, BHT, BHA), metal chelation (EDTA), or enzymatic action. On skin, they neutralize reactive oxygen species (ROS) generated by UV radiation and pollution, preventing lipid peroxidation and DNA damage.

// 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.

// 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.

// Evidence: Emollient ingredients create smooth, soft skin by filling spaces between corneocytes in stratum corneum. These include esters (isopropyl palmitate), oils (jojoba, argan), fatty alcohols, and silicones. The mechanism involves spreading on skin surface, filling microscopic irregularities, and creating lubricious film. Effects are immediate tactile improvement and visual smoothing. Emolliency measured by spreading coefficient and skin feel assessments.
