The rate of sebum excretion from the forehead skin of patients with early breast cancer was found to be just significantly higher than in age-matched control women. This may indicate that some breast cancer patients have an increase in circulating or tissue-bound sebotrophic hormones, or a decrease in their inhibitors.

Acne vulgaris is a common inflammatory condition that multi-factorial and impacted by both intrinsic extrinsic features. Several previous studies have assessed for correlations between factors such as circulating hormones, stress, or the microbiome. However, there not been any specifically against lesion counts differentiating non-inflammatory counts. Here, we correlate several acne lesions. Tw...

The delay between synthesis and excretion of sebum in sheep and in man was determined by measurement of the time between intradermal injection of (1"C ]acetate and the appearance of a peak of radioactivity in the skin surface lipids at the injection site. In two sheep, a peak of radioactivity in the total surface lipid occurred 6 days after injection, and this is interpreted as the time require...

BACKGROUND Rosacea and melasma are two common skin conditions in dermatology. Both conditions have a predilection for the centrofacial region where the sebaceous gland density is the highest. However it is not known if sebaceous function has an association with these conditions. AIMS AND OBJECTIVES We aimed to assess the relationship between facial glabellar wrinkle severity and facial sebum ...

BACKGROUND AND OBJECTIVE A minimally invasive fractional radiofrequency microneedle (FRM) device has been used in skin rejuvenation and acne scars, and a recent pilot study demonstrated the positive therapeutic effect on acne. We evaluated the efficacy of FRM device for acne vulgaris in Asians and conducted objective measurement to assess its effect on sebum production. PATIENTS AND METHODS T...

OBJECTIVE After pilot and preliminary studies aimed at identifying pertinent biochemical parameters, a multicenter clinical study was performed to evaluate the effect of pollution on human skin. METHODS The clinical study was performed in collaboration with the 'Centre Régional de lutte contre le cancer de Montpellier' and the 'National Institute of Public Health of Mexico' on 96 subjects in ...
