H Khan, N Akhtar, A Ali
The skin is fortified with a setup of lipophilic and hydrophilic, enzymatic and non-enzymatic antioxidant systems. Ascorbyl palmitate (AP) and sodium ascorbyl phosphate (SAP) are reported as lipophilic and hydrophilic antioxidants, respectively used for skin care. Present study was aimed to assess the combined AP (in oil phase) and SAP (in aqueous phase) via multiple emulsion (ME1) for controlling sebum secretions in healthy human females. FTIR analysis of AP and SAP was performed for identification. Multiple emulsions (ME1 and control) were prepared and analyzed for physical stability...

The relationship between diet and acne is highly controversial. Several studies during the last decade have led dermatologists to reflect on a potential link between diet and acne. This article presents the latest findings on a potential impact that diet can have on pathogenesis of acne vulgaris. The association between diet and acne can no longer be dismissed. Compelling evidence shows that high glycemic load diets may exacerbate acne. Dairy ingestion appears to be weakly associated with acne and the roles of omega-3 fatty acids, dietary fiber, antioxidants, vitamin A, zinc and iodine remain to be elucidated...

Mammalian skin is characterized by the presence of sebaceous glands (SGs), which develop with the hair follicle and whose predominant cell type is the sebocyte. Sebocytes are epithelial cells that progressively accumulate lipids and eventually release their content (sebum) by holocrine secretion as cells disrupt. In addition to thermoregulatory and pheromonal actions, numerous additional functions have been demonstrated or postulated for sebum, including antimicrobial and antioxidant activities. The SG has also been involved in the pathogenesis of skin diseases as acne vulgaris and some forms of alopecia...

AIM: Polycystic ovary syndrome (PCOS) affects 5-10% of women of childbearing age and manifests itself through oligomenorrhea, anovulation, hirsutism, micro-polycystic ovaries. Insulin resistance is a characteristic of PCOS patients and is more pronounced in obese patients. Insulin resistance and consequent hyperinsulinemia are related to many aspects of the syndrome such as hyperandrogenism, reproductive disorders, acne and hirsutism. In the long-term it may increase the risk of cardiovascular disease and negatively affect lipid profile and blood pressure...

Most orally administered polyphenols are metabolized, with very little absorbed as aglycones and/or unchanged forms. Metabolic and pharmacokinetic studies are therefore necessary to understand the pharmacological mechanisms of polyphenols. Jumihaidokuto (JHT), a traditional Japanese medicine, has been used for treatment of skin diseases including inflammatory acne. Because JHT contains various types of bioactive polyphenols, our aim was to clarify the metabolism and pharmacokinetics of the polyphenols in JHT and identify active metabolites contributing to its antidermatitis effects...
