Mutations in Mitochondrial DNA as Principal Aging Factor

Impaired functioning of mitochondria is a very important factor in aging. Irradiation of normal human fibroblasts with UV was shown to increase the frequency of mutations in the mitochondrial DNA. Treatment of the fibroblast culture with a nanoemulsion containing coenzyme Q10 and vitamin E acetate was found to protect the mitochondrial DNA against UV-induced mutations.

Perfluoropolyether Phosphate and Skin Renewal: The Therapeutic Index

The skin renewal and irritation properties of two different gels containing PFPE phosphate were compared to a glycolic acid gel. Results showed that PFPE phosphate exhibited activity similar to glycolic acid with a more favorable safety profile, and hence, a better therapeutic index.

Cranberry Seed Oil Rising in Popularity

Cranberry is abounding, and, no, not because Thanksgiving is at hand in the United States.

CoQ10 Emerges as the New Beauty Antioxidant

Coenzyme Q10 (CoQ10) is rapidly becoming a more popular antiaging ingredient in skin care.

Antiaging Effects of a Skin Repair Active Principle

A particular extract of DNA from the gonadic tissue of male sturgeons is shown to have cell renewal effects with possible antiaging benefits for skin moisture, thickness, elasticity and micro-wrinkles.

Wrinkle Reduction by Stimulation of the Skin’s Mechanical Resistance

A rye extract rich in arabinoxylans is shown to stimulate the synthesis of mechano-receptor proteins and alpha-SMA fibers in the skin, improving the skin’s mechanical resistance and reducing the appearance of gravity wrinkles.

Folk Medicine Meets Today's Skin Care

Silab launches a regenerative and tonic care ingredient based on 2000 years of folk medicine.

Building a Better Barrier from the Inside Out

Ursolic acid encapsulated in liposomes has demonstrated an ability to stimulate ceramide synthesis in keratinocytes, resulting in a barrier that is stronger and recovers more quickly from disruption.

The Stabilization of Linoleic Acid by Complexation with Alpha-cyclodextrin

In the form of a molecular inclusion compound with α-cyclodextrin, linoleic acid effectively is protected against oxidation. Investigations into the storage and light stability, olfactory tests and headspace analysis of the formulations give evidence of the stability of a suitable inclusion compound.

Improving Hair Strength

This article describes hair structure and the results of tensile testing experiments on hair that had been treated with betaine. It postulates a possible theory for the improvement in hair strength.

Applications of Essential Fatty Acids in Skin Care, Cosmetics and Cosmeceuticals

Skin benefits of essential fatty acids include enhancement of cell membrane structure and function, barrier maintenance and recovery, anti-irritant and anti-inflammatory effects and penetration enhancement. Their metabolism is described and their use in cosmetics and cosmeceuticals is surveyed.

A New Active from Germinated Seeds Boosts HSP Expression in Skin's Natural Defenses

A new active ingredient obtained from germinated seeds improves the natural skin defense by boosting HSP expression in the keratinocytes in response to stress exposure.
