It's All in the Perception
By: Rachel Grabenhofer, Cosmetics & Toiletries…
Thinking about products, consumer happiness is an outcome of consumer perception. And as the industry knows, consumer perception is crucial to product success. It’s the difference between skepticism and trust, like and dislike, and, ultimately, the sale or no sale

Fischer-Tropsch vs. Mineral Products for Moisturization
By: Madelyn Bekker, PhD; Nicolaas Rossouw Louw; an…
Differing amounts of Fischer-Tropsch (FT) wax were used in petroleum jelly and final cosmetic emulsions to evaluate moisturizing effects in skin. FT wax was shown to perform as well or better than traditional mineral-derived products.

Comparison of Age Determination by Three Evaluation Methods: Self-assessment, Expert Grader and Naïve Grader
By: Rosanna Mootoo, Nima Gohil, Cristina Stroever…
This exploratory study investigates how consumers perceive age, using objective and subjective approaches. Results of this study suggest that when a subjective approach is implemented for age determination, subjects affix their emotions to the evaluation. The reverse logic was applicable for the expert and naïve grader methods, as grader results appeared more neutral than the self-assessment.

Testing Moisturizing Claims for Skin
By: Chris McLeod, HPCI Media
Although this author cannot deny that moisturization capabilities can provide relief for those who suffer from flaky, itching or irritated and dry skin, it would be careless not to acknowledge the marketing-based beguilement within this moisturization sector.

Testing Tactics—Consumer vs. Scientific Language: Relating In vivo to In vitro
By: Trefor Evans, PhD, TA Evans LLC
It should perhaps go without saying that consumer products are sold using consumer language. Market researchers and consumer scientists spend a great deal of time studying their target audience and learning this vocabulary, which subsequently allows the recounting of product benefits in the same terminology.

Adjusting Substrate/Product Interfacial Properties to Improve In vivo/In vitro SPF Correlation
By: S. Miksa, D. Lutz and J. Ongenaed, HelioScreen…
This work evaluates the impact of a plasma treatment on test substrates to modify their surface energy, to more closely correlate in vitro SPF measurements with in vivo measurements—without chemically altering the test products. The authors chose the level of plasma modification to use on a substrate based on in vivo values; they explain how to choose it regarding specific formulas in a further paper.

Consumer Perception of Fine Lines and Wrinkles Assessed by Qualitative Methods
By: Rosanna Mootoo, Stephanie Basile, Cristina St…
There are varying definitions, associations and overall impressions of fine lines and wrinkles among different consumer segments. The findings of this study offer invaluable insight into consumers’ opinions, and by qualitative in-depth interviews, they provide a well-defined vernacular for aging descriptors. This language is critical for developmental research, consumer evaluation and marketing within the cosmetic industry.

Determining Korean Consumers’ Degree of Exposure to Lipstick and Face Creams
By: Kwangsuk Joo, Ongsoo Kim, Heonsik Kim and Jeu…
This study describes methods used in a Korean study to calculate consumer exposure to lipstick and face creams. The average amount applied daily was estimated and compared with data collected by weighing containers before and after use. The data collected was 1.8 to 1.6 times greater than the estimate, so although the survey represented real use patterns, the actual data was more accurate.
