The skin innately possesses metabolic pathways and receptors to protect against external assaults. Here, one protective component, 7-dehydrocholesterol or provitamin D, naturally present in the skin, is described, which serves as the precursor for active metabolites that influence the formation and maintenance of barrier function, the activation of antimicrobial peptides, photoprotective activities, and protection against senescence.

Dormant Leucojum aestivum bulb extract is shown by the author to provide antiaging benefits including: slowing the proliferation of melanocytes and keratinocytes potentially to reduce age spots and slow cellular aging; reducing wrinkle formation by inhibiting muscle cell contractions; and increasing SOD expression in the skin to boost its natural defenses.

Degradation of dermal and epidermal proteins and the reduced proliferation of collagen and hyaluronic acid in the dermis occur during aging. Thus, antiaging technologies must to correct these deficiencies to induce skin regeneration and combat the signs of aging. Data presented here demonstrates that ECM-derived tetrapeptides have the potential to counterbalance ECM degeneration.

Complexity theory is used here to explain the formation and properties of polyelectrolyte complexes, whereby organized structures built through self-association exhibit synergistic properties. These materials can create new compounds and offer new benefits, as shown by the present work in which a complex based on PVM/MA copolymer and polyquaternium-28 is used to treat damaged hair.
