How to Prove 'Rub-resistant' Sun Protection

Today’s consumers desire sunscreens that are not only more effective against UV radiation, but also provide water, sand, sweat and rub resistance. These authors propose a new in vitro test to assess and compare rub resistance factors, which they illustrate here by testing 20 sun care products.

Modifying Hair’s Structure From the Inside

Changing hair properties is a regular function of daily-use treatments. But what other methods can be used? Altering the hair’s internal structure may be the next way to achieve these changes.

Silab’s Mitokinyl Battles Urban Pollution

Silab has introduced Mitokinyl, an anti-pollution natural active ingredient, which fights damaging environmental stressers.

Coiffed Conundrum: Equating the Measurement of Hair Shine

Shine constitutes the ability for light to reflect off of surfaces. For consumers, perceived shine is indicative of healthy hair. For marketers, it is the gateway to hair product benefits claims. But how can shine be measured to support those claims?

Matmarine Blue Ingredient Leaves Matte Finish

To help produce a product leaving a matte finish to last the whole day, 2% of Lipotec’s Matmarine blue ingredient (INCI: Pseudoalteromonas Ferment Extract) was applied to a BB cream.

Photostability Test for Additional Sunscreen Claims, Part III: New Claim

Proposed here is an in vitro method, based on UV transmission measurements at two irradiation doses, to test and rank sunscreens based on their photostabilities. This approach was used to assess some 107 sunscreens and shows how, by strictly controlling key parameters, comparisons between the photostabilities of products can be made, with potential for new label claims.

Photostability Test for Additional Sunscreen Claims, Part II: Calculations and Results

Proposed here is an in vitro method, based on UV transmission measurements at two irradiation doses, to test and rank sunscreens based on their photostabilities. This approach was used to assess some 107 sunscreens and shows how, by strictly controlling key parameters, comparisons between the photostabilities of products can be made, with potential for new label claims.

Photostability Test for Additional Sunscreen Claims, Part I: Protocol Setup

Proposed here is an in vitro method, based on UV transmission measurements at two irradiation doses, to test and rank sunscreens based on their photostabilities. This approach was used to assess some 107 sunscreens and shows how, by strictly controlling key parameters, comparisons between the photostabilities of products can be made, with potential for new label claims.

Terminalia Chebula for Preventive and Restorative Anti-aging Benefits*

This paper examines a tannin-enriched Terminalia chebula extract. Discussed are its mechanisms for preventative and restorative anti-aging effects, and skin pigmentation control. A pilot clinical study further confirms the extract’s bioactivity to reduce wrinkles and pigmentation. Improvements in yellowish skin tones also were observed, likely due to glycation reversal.

Beating the Damaging Effects of Heat on Hair

Heat treatments are among the more popular methods for achieving straight hair, yet their high temperatures are quite damaging to the hair’s structures. Learn about the damaging effects and suggested solutions for repairing heat-damaged hair.

Hidden Hair Damage and the Importance of Multiple Tests

It is of paramount importance for hair researchers to know the history of hair at the time of applying a treatment. The lack of such knowledge can create misleading results. Thus, a stress-strain test in both dry and wet states can provide a rapid means to check the reliability of the information collected, as is shown here.
