Subvisible microscale texture is present on the crista cutis of the skin and interacts with incident light to create a soft and radiant 'shitsukan' appearance. [PDF]

Int J Cosmet Sci
Subvisible microscale texture on the skin’s surface is not visible to the naked eye. However, this structure plays a crucial role in regulating the optical properties of the skin’s surface contributing to skin appearances by making the skin appear softer, more radiant, and smoother.

Performance of hybrid diffuse reflectance spectroscopy (HDRS-ISO 23698) methodology for assessment of sunscreen protection in the ALT-SPF Consortium validation study. [PDF]

Int J Cosmet Sci
Hybrid Diffuse Reflectance Spectroscopy (HDRS), now ISO 23698, demonstrated bioequivalence to gold‐standard SPF, UVA‐PF, and CW methods, achieving similar accuracy with improved variability after training. This new non‐erythemal approach enables safe non‐invasive sunscreen performance assessment on human skin, expanding possibilities for evaluating ...

A comparison between silicone‐free and silicone‐based emulsions: Technological features and in vivo evaluation

International Journal of Cosmetic Science, Volume 44, Issue 5, Page 514-529, October 2022., 2022
Abstract Objective Nowadays, the use of silicones in cosmetic formulation is still controversial, given that “natural” or “biodegradable” components are preferred. Often, the exclusion and/or the discrimination of these excipients from cosmetic field are unmotivated because all things cannot be painted with the same brush.

New approach for hair keratin characterization: Use of the confocal Raman spectroscopy to assess the effect of thermal stress on human hair fibre

International Journal of Cosmetic Science, Volume 44, Issue 5, Page 588-601, October 2022., 2022
Confocal Raman Spectroscopy for the evaluation of the thermoprotective effect of the hair product. Abstract Objective The objective of our research was to investigate the heat‐protecting effect of a product ex vivo and in vivo on human hair fibres. Methods A preparatory study was carried out in order to determine an optimal threshold of thermal stress.

Chemically characterizing the cortical cell nano‐structure of human hair using atomic force microscopy integrated with infrared spectroscopy (AFM‐IR)

International Journal of Cosmetic Science, Volume 44, Issue 1, Page 42-55, February 2022., 2022
Abstract Objective The use of conventional microscopy and vibrational spectroscopy in the optical region to investigate the chemical nature of hair fibres on a nanometre scale is frustrated by the diffraction limit of light, prohibiting the spectral elucidation of nanoscale sub‐structures that contribute to the bulk properties of hair.

Photodynamic Therapy for Cancer: Principles

Canadian Journal of Gastroenterology and Hepatology, Volume 16, Issue 6, Page 393-396, 2002., 2002
The principles of photodynamic therapy (PDT), using drugs (photosensitizers) that are activated by light to become cytotoxic, provide the basis for understanding the current and potential future clinical applications in gastroenterology, general oncology and other specialities.
