Mitigating 'Maskne:' Boldo to Balance Sebum, Bacteria and Redness in Acneic Skin

Peumus boldus (boldo) extract was tested for effects on sebum production, S. aureus growth and C. acnes lipase activity in vitro, as well as on skin redness in vivo. This work aimed to develop a natural ingredient to control sebum, inhibit microbes and their activity, and reduce redness in acne-αfflicted skin.

Microbiological test methods for w/o formulas have raised questions in terms of their suitability. They also require a more critical view of the results than other product types. This first article in a two-part series reviews the limitations of such methods and options for their optimization. It also critically observes to what extent test results provide relevant information for an appropriate safety assessment. Part II, in August 2022, will explore a holistic approach to more accurately assess microbiological safety.

Determining Preservative Efficacy in W/O Formulas, Part I: Test Performance and Limitations

Microbiological test methods for w/o formulas have raised questions in terms of suitability. They also require a more critical view of the results than other product types. This first article in a two-part series reviews the limitations of such methods.

Fluorescence Lscm To Assess The Penetration Of Low Molecular Protein Hydrolyzates Into Hair

Fluorescence LSCM to Assess the Penetration of Low Molecular Protein Hydrolyzates Into Hair

The present study uses confocal laser scanning fluorescence microscopy to assess the penetration of protein hydrolyzates into hair. While higher amounts of protein were found in the cuticle, still significant quantities were observed in the cortical parts of hair, and this penetration was enhanced by longer incubation times.
