Hydrogenated palm glyceride

// Evidence: Light stabilizers prevent photodegradation through UV absorbers that convert light energy to heat (benzophenones, benzotriazoles), radical scavengers (hindered amine light stabilizers), or quenchers that deactivate excited states. These protect photosensitive ingredients like fragrances, colors, and vitamins from degradation during storage. Mechanism involves absorbing UV radiation or scavenging photo-generated free radicals.

// 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.

// Evidence: Cleansing surfactants specifically formulated for removing sebum, dirt, and impurities. Primarily anionic (sodium laureth sulfate, sodium cocoyl isethionate) and amphoteric surfactants (betaines). Mechanism involves reducing surface tension enabling water to wet oily surfaces, solubilizing lipophilic materials in micelles, and emulsifying oils for rinse-off. Cleansing efficacy balanced with mildness by surfactant selection, concentration, and pH optimization. Must avoid excessive lipid removal that compromises barrier function.
