Profile of Ascorbic Acid

L-Ascorbic acid (AscA), more commonly referred to as vitamin C, is best known for its vital role in human health and nutrition, where it functions as a cofactor in enzymatic reactions, such as collagen synthesis, and as an antioxidant.

Tetrapeptide Targets Epidermis Cohesion

Most antiaging products claim to act on the dermis; however, the epidermis, a key element of cutaneous aging, is often forgotten. In the present study, researchers selected an acetylated tetrapeptide for its effect on epidermis cohesion, triggered by activity on syndecan-1 and collagen XVII; these effects are confirmed in vivo.

Grapefruit Extract Cream: Effects on Melanin in Skin

The current work aimed to formulate a stable w/o emulsion containing grapefruit extract by entrapping the extract in the inner aqueous phase. The final formula was found to have skin-whitening, moisturizing, cleansing and antiwrinkle effects, among others.

A Direct Connection to Melanocytes

An academic study of the pathway of UV-induced pigmentation may have created a safe tan for sunseekers. Scientists at the Dana-Farber Cancer Institute, Harvard Medical School, have begun research and evaluation of the compound forskolin, which they believe darkens skin pigmentation successfully without the use of self-tanners and without sun exposure.

Cellulite: Evolving Technologies to Fight the 'Orange Peel' Battle

This article focuses on the structure of cellulite and examines materials that claim to affect its appearance via mechanisms such as lipolysis, lipogenesis, water drainage, tissue repair and the firming of skin.

Pisum Sativum Extract for Safe- and Self-Tanning

The cosmetic industry is challenged to develop active ingredients to provide the skin with a natural, healthy glow without sunlight exposure. Here, the author examines the effects of Pisum sativum extract on melanocytes and shows a time- and dose-dependent increase in skin tone, also suggesting the material could protect skin from UV damage.

Leucojum aestivum Bulb Extract for Antiaging Benefits

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.

Profile of Salicylic Acid

2-Hydroxybenzoic acid, or salicylic acid (SA), is among the most important medicinal compounds ever discovered. Since ancient times, humans have benefited from the therapeutic effects of naturally occurring SA precursors, which readily metabolize to SA and provide analgesic, anti- inflammatory and antipyretic benefits.

Slowing Intrinsic and Extrinsic Aging: A Dual Approach

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.

Lessons in Peptides and Finding Balance

On April 16, 2013, in Paris, in-cosmetics organizers presented Karl Lintner, PhD, with the Lifetime Achievement Award; a well-deserved honor as the father of Matrixyl, who has dedicated much of his life to identifying and validating active cosmetic technologies.

Naolys Introduces Anti-aging Active Derived from Rutin and Hibiscus

Naolys has introduced an anti-aging plant cell complex comprising an active cell of "bluebird" hibiscus and a rutin molecule from Japanese knotweed.

Lightening, Boosting and Protecting with Colorless Carotenoids

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.
