Inflammation is the bodyâ€™s natural immune response to harmful stimuli, including pathogens, allergens, irritants, or damaged cells. It is classically characterized by redness, swelling, heat, and pain. In normal circumstances, inflammation is a short-term reaction that serves to combat harmful stimuli and promote healing. In the case of inflammatory disorders, inflammation is not self-regulating and becomes continuous. This type of chronic inflammation is associated with degenerative disease and premature aging. Recent research suggests a strong link between oxidative stress and chronic inflammation, due to immune response triggered by constant damage from reactive oxygen species.
Intrinsic aging, also known as chronological or natural aging, refers to changes in the structure and function of skin that occur as we age naturally. Beginning around out mid-20s, physiological changes cause collagen production to slow and skin to loose its elasticity. Dead skin cells do not shed as quickly, and the turnover of new cells begins to slow. Intrinsic aging results in skin that is thinner, less elastic, and finely lined. Additionally, changes in hormone levels may reduce the amount of oil produced, resulting in dry, flaky skin. Also see Extrinsic Aging.

Isododecane is a hydrocarbon ingredient used as an emollient and solvent in cosmetics formulations. It has a relatively low viscosity, and density, making it ideal for spreading other ingredients evenly over the skin. It also helps skin remain hydrated by protecting against transdermal water loss.
Isoflavones are phytochemicals found naturally in high concentrations in soybeans. Also known as phytoestrogens, soy isoflavones have a chemical structure that is very similar to the hormone, estrogen, and are able to bind to estrogen receptors in the human body. As a result, soy isoflavones are capable of increasing collagen synthesis and skin thickness when applied topically. Studies have also shown that soy isoflavones are potent antioxidant and anti-inflammatory agents, and are capable of protecting skin inhibiting photodamage from UVB radiation.
