Clean and Green: A Review of Modern Day Surfactants and Emulsifiers

Many certified organic shampoos and body washes use soaps such as potassium cocoate as their primary cleansing agent, partially due to a lack of suitable, organically approved foaming alternatives. This article reviews the use of modern surfactants and emulsifiers developed based on a green and eco-conscious philosophy.

Formulation and Evaluation of Self-tanners

Self-tanning preparations are becoming increasingly important for consumers desiring a tanned look without exposing themselves to undue harm. The present article reviews DHA and other self-tanning active ingredients and their mechanisms of action. Formulating hallenges such as stability and ingredient interactions are discussed, as well as the evaluation and regulation of self-tanning products.

Soaking up the Self-Tan: The Pros and Cons of DHA and Self-tanners

Many people utilize non-UV tanning methods to meet fashion demands without exposing themselves to UV radiation. This article reviews the health benefits and possible drawbacks of dihydroxyacetone, the main active ingredient in self-tanning products.

Antiaging Benefits of Topical and Oral Lutein

Research suggests that both topical and oral lutein can increase skin hydration and decrease skin lipid peroxidation, providing antiaging benefits to skin.

Anticellulite Combo of Coriander and Sweet Orange

Silab has combined the fruits of coriander and sweet orange in a cosmetic ingredient to reduce hard cellulite.

The Photostability and Photostabilization of trans-Resveratrol

In this study, the effects of ultraviolet radiation (UVR) on trans-resveratrol were documented, finding that UV radiation causes it to undergo rapid and extensive photoisomerization and some photodecomposition. The antioxidant activity of trans-resveratrol is correspondingly reduced. However, in the presence of ethylhexyl methoxycrylene, a photostabilizer used in sunscreens, the effects of UV exposure on trans-resveratrol are minimized, thereby preserving its antioxidant activity and, presumably, its bioavailability.

Metabolism and Modulation of Hyaluronan Levels in Skin

This is the last in a series of articles that review the literature on hyaluronan, which also sometimes goes by the name hyaluronic acid.

Penetration And Metabolism Of Isoflavones In Human Skin

This human study shows that the isoflavone aglycone genistein penetrates significantly better into the skin when it is formulated in a liposomal preparation. The corresponding isoflavone glycoside genistin is not hydrolyzed to the biologically active aglycones upon topical application.

Retinoids For Cosmetics

Review and Modern Advances of Retinoids for Cosmetics

For skin cancer, skin aging and acne, retinoids have proven both preventive and therapeutic. Successful efforts toward more bioavailable vitamin A derivatives and retinoid formulations have increased their use for cosmetic benefits. Recent work to further optimize retinoids and reduce their side effects has yielded a new generation of promising molecules, described here.

Testing the Fate (and Exposure) of Cosmetic Ingredients

Risk and exposure go hand-in-hand. So when researchers dared to publish a new method to assess the exposure and fate of cosmetic ingredients, we couldn't help but give them exposure, in this review.

Photostabilization of Retinol and Retinyl Palmitate by Ethylhexyl Methoxycrylene

This study examines the photostability of retinol and retinyl palmitate, finding they break down rapidly when exposed to UV radiation in the 290–400 nm range. This severely reduces their concentrations in finished formulations. However, when combined with ethylhexyl methoxycrylene, these retinoids are shown to be protected against photodegradation, thus preserving their concentrations both during the manufacturing process and following application to the skin.

Penetration of Cosmetics Into and Through the Stratum Corneum

The penetration routes of substances through the stratum corneum and how these transport pathways function are becoming better understood. Despite this progress, however, the penetration mechanisms of cosmetic formulations remain mysterious. This overview presents current knowledge on the various pathways of penetration, and suggests that even if cosmetic formulations penetrate no deeper than the surface, their efficacy may still be optimal.
