research Influence of Liposomes and Niosomes on the In Vitro Permeation and Skin Retention of Finasteride
Liposomes and niosomes can increase finasteride retention in the skin.
research Targeted Determination of Residual Sex Hormones in Cosmetics Using Magnetic Solid-Phase Extraction with Isotope-Labeled Internal Standards by UHPLC-MS/MS
A new method effectively detects trace sex hormones in cosmetics, ensuring safety.
research Adrenal steroid precursors exert potent androgenic action in the hamster sebaceous glands of flank organs and ears.
Certain adrenal hormones can strongly stimulate oil gland growth in hamster skin, similar to male hormones.
research Influence of Liposome Type and Skin Model on Skin Permeation and Accumulation Properties of Genistein
Elastic liposomes deliver genistein through haired skin better than conventional liposomes.
research Influence of phosphorus on morphology and physiology of freshwater Chaetophora, Draparnaldia and Stigeoclonium (Chaetophorales, Chlorophyta)
Phosphorus limitation causes significant hair growth in certain algae.
research Human stratified squamous epithelia differ in cellular fatty acid composition
Fatty acid composition in human skin, mouth, and hair cells varies with keratinization, and cultured cells show essential fatty acid deficiency.
research Sebocytes are the Key Regulators of Androgen Homeostasis in Human Skin
Sebocytes play a key role in controlling androgen levels in human skin.
research Preparation of 4-aryl-2-trifluoromethylbenzonitrile derivatives as androgen receptor antagonists for topical suppression of sebum production
Scientists made a chemical (compound 4e) that can be applied on skin to reduce oil production, which can help with acne, but it might cause skin sensitivity to light.
