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.
