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.

In this dual approach to antiaging, intrinsic factors are first addressed by slowing cell proliferation in skin via a technology based on dormins—in this case, extracts from dormant Narcissus tazetta bulb. Then, to protect against extrinsic aging, colorless carotenoids are employed to absorb UV radiation and prevent oxidative stress damage.

The use of steroids to treat atopic dermatitis (AD) often causes side effects; thus, the authors present a blend of plant-derived materials designed as an alternative treatment or an adjuvant therapeutic agent. Through in vitro and in vivo evaluations, the blend is shown to provide effective anti-inflammatory and AD-mitigating effects.

Fragrances are blends of synthetic chemicals, essential oils and solvent extracts, known as absolutes. Recent research has evaluated the effects of these natural aromatic products, revealing they can impact processes in skin. Here, the author describes how a fragrance with specially selected naturals can provide a pleasant scent as well as impart cosmetic activity.

Phytoene and phytofluene (P&P) are carotenoids that are precursors in the biosynthetic pathway of other carotenoids. These materials occur naturally in microorganisms, algae and other plants and exhibit benefits for skin care including skin lightening, anti-inflammatory activity and protection against UV and oxidative damage, as is shown here.

In the present report, the authors developed a foundation specifically tailored to the needs and preferences of elderly women and, through scientific measurement, confirmed that wearing the right makeup leads to brain activation. Studies validated that among elderly women, satisfaction with self-appearance could contribute to higher self-confidence, improved outlook and resistance to neurological ailments.

A combination of Chinese herbs is shown here, by gene array analysis, to stimulate the skin’s resistance against free radicals, oxidative stress and toxic molecules, while also reducing extracellular matrix degradation. The extract also is shown to help against skin irritation in vivo.
