Occupational irritant contact dermatitis (ICD) affecting the hands is a common and difficult-to-manage condition. Occupations that necessitate contact with harsh chemicals, use of alcohol-based disinfectants, and frequent hand washing elevate the risk of ICD. Management strategies that do not adequately prevent accumulated damage and repair skin, can develop into chronic dermatoses which negatively impact work productivity and quality of life. A 2-step skin-care regimen (Excipial Daily Protection Hand Cream (EP) and Excipial Rapid Repair Hand Cream (ER), Galderma Laboratories, L...

BACKGROUND: Although cosmetic procedures have a significant impact on certain aspects of aging, such as deep, wrinkling, sagging, and volume loss, they fail to address the overall quality of the skin. METHODS: Daily skincare routines potentially can have a significant long-term impact on the overall quality of a person's complexion. RESULTS: By expanding our product knowledge, we can help our patients individualize their at-home skincare routine using effective products and ingredients designed to address their specific skin concern and support the professional care we deliver...

A triaxial force-sensitive microrobot was developed to dynamically perturb skin in multiple deformation modes, in vivo. Wiener static nonlinear identification was used to extract the linear dynamics and static nonlinearity of the force-displacement behavior of skin. Stochastic input forces were applied to the volar forearm and thenar eminence of the hand, producing probe tip perturbations in indentation and extension. Wiener static nonlinear approaches increased the variance accounted for by 0.1 % to 3.4 % over linear approaches, to 94 % to 97 %...

BACKGROUND: Chemical peels are versatile treatments that involve chemical exfoliation of the skin for cosmetic improvement. Deeper peels produce more significant results, but can be associated with longer healing time and potential complications. Novel chemical resurfacing treatments (AGE and MELA) were developed in Europe to produce skin resurfacing via controlled inflammation to promote cell regeneration with minimum negative effects associated with conventional peelings. The AGE Resurfacing regimen is indicated for the treatment of photoaging, and consists of multi-ingredient peeling solution with trichloroacetic acid, pyruvic acid, salicylic acid, mandelic acid, and lactobionic acid...

A 14-week single-center clinical usage study was conducted to test the efficacy of a peptide treatment serum and supporting skincare regimen in 29 women with mild to moderately photodamaged facial skin. The peptide treatment serum contained gamma-aminobutyric acid (GABA) and various peptides with neurotransmitter inhibiting and cell signaling properties. It was hypothesized that the peptide treatment serum would ameliorate eye and facial expression lines including crow's feet and forehead lines. The efficacy of the supporting skincare regimen was also evaluated...

BACKGROUND: One of the key strategies for anti-ageing in the cosmetics industry today is to target the structural changes responsible for ptosis of the skin, given its impact on age perception. Several objective and non-invasive methods are available to characterise the biomechanical properties of the skin, which are operator-dependent, involving skin contact and providing single-dimensional numerical descriptions of skin behaviour. The research introduces the DynaSKIN, a device using non-contact mechanical pressure in combination with fringe projection to quantify and visualise the skin response in 3-dimensions...

Sun-exposed skin is characterized by superficial changes such as wrinkles, sagging and pigmentary changes, and also many internal changes in the structure and function of epidermis, basement membrane (BM) and dermis. These changes (so-called photoageing) are predominantly induced by the ultraviolet (UV) component of sunlight. Epidermis of UV-irradiated skin produced several enzymes such as matrix metalloproteinases (MMPs), urinary plasminogen activator (uPA)/plasmin and heparanase, which degrade dermal collagen fibres and elastic fibres in the dermis, and components of epidermal BM...

Psoriasis is a chronic inflammatory disease, affecting about 3% of the worldwide population. Although there are many therapeutic options available today for psoriasis, none of them can be considered as the gold standard treatment for maintaining a sustained period of remission. The aim of this study was to investigate whether a maintenance dosage of Michaels® Soratinex® product family is effective in maintaining a symptom-free state for patients in remission. Fifty patients (23 male, 27 female), aged 18-58-years-old (mean age: 38...

Psoriasis is a chronic, inflammatory, recurrent, genetically determined dermatitis that affects the skin and joints. Many patients affected by this condition seek alternatives and complementary treatment options such as herbal medicines. In order to establish the safety of these products, trials, according to medical standards should be performed to provide the highest quality of data. The aim of this study was to assess the efficacy and safety of an Australian series of herbal skincare products [Dr. Michaels® (Soratinex®) skin-care products for psoriasis] for the management of stable chronic plaque psoriasis...

Facial rejuvenation can be categorized into skincare and facial contouring. Research and development of cosmeceuticals is aimed at addressing the major signs of photoaging: wrinkles, dyschromia, and sallowness. Assessment of photoaging comes in clinical and photographic forms; a photonumeric scale developed by Griffiths et al. has been assured of its validity and reliability for the assessment of severity of photoaging in qualitative studies. Treatment of photoaging comes in two categories: preventive and reversal of signs; whilst sunfactors are the most efficient and essential in preventing photodamage, research and development of cosmeceuticals for facial rejuvenation has been robust, thanks to several landmark studies in the last fifty years, funded by some of the forerunners in contemporary cosmetic industry...

A 52-year-old non-smoking beautician using a skincare device spraying steam and ozone (a "vapozone" facial steamer) was referred for progressive dyspnea and dry cough during working periods. Although spirometry was normal, she had decreased diffusing capacity of the lung for carbon monoxide, bronchiolitis with air trapping on high-resolution CT scan and 60% lymphocytosis by bronchoalveolar lavage. Twenty-six antigens were tested and serum-specific precipitins were found mainly against Pseudomonas sp. and Mycobacterium mucogenicum...

Mosquitoes display biting preferences among different sites of the human body. In addition to height or convection currents, body odour may play a role in the selection of these biting sites. Previous studies have shown that skin emanations are important host-finding cues for mosquitoes. In this study, skin emanations were collected from armpits, hands and feet; the volatile profiles were analysed and tested for their attractiveness to the malaria mosquito Anopheles coluzzii. Skin emanations collected from armpits were less attractive to An...

The prime objective of current investigation was to develop a topical skin care cream (w/o) loaded with Ananas comosus extract versus placebo control, and evaluated non-invasively for changes in skin barrier function i.e., epidermal hydration levels and transepidermal water loss (TEWL), on healthy human volunteers. Active cream carrying 2% extract of Ananas comosus in the internal phase of w/o emulsion was prepared while placebo contained no extract. Stability assessment of both creams was performed at various storage conditions 8, 25, 40 degrees C, 40 degrees C + 75% RH (relative humidity) and 50 degrees C...

Pure water was used as the eluent for separation of coumarin, vanillin and ethyl vanillin at temperatures ranging from 100 to 200°C using a homemade subcritical water chromatography (SBWC) system. Chromatographic separations were performed on five commercial columns including XTerra MS C18, XBridge C18, Zorbax RRHD Eclipse Plus, Zorbax SB-Phenyl and Zorbax SB-C18 columns. The retention time of all three solutes decreased with increasing water temperature. The shortest retention time among all acceptable separations, less than 4 min, was achieved on the Zorbax SB-C18 column at 200°C...

Normal aging and photoaging of the skin are chronic processes that progress gradually. The extracellular matrix (ECM), constituting over 70% of the skin, is the central hub for repair and regeneration of the skin. As such, the ECM is the area where changes related to photodamage are most evident. Degradation of the ECM with fragmentation of proteins significantly affects cross talk and signaling between cells, the matrix, and its constituents. The accumulation of collagen fragments, amorphous elastin agglutinations, and abnormal cross-linkages between the collagen fragments impedes the ECM from its normal repair and regenerative capacity, which manifests as wrinkled, non-elastic skin...

BACKGROUND: From birth, the functional properties of the neonatal epidermal barrier mature whereby the stratum corneum (SC) hydrates and the skin surface acidifies. The identification of a thinner infant SC compared with adults suggests underdeveloped mechanisms underlying differentiation and desquamation. OBJECTIVES: To assess the functional properties of the neonatal SC from birth, in conjunction with the quantification of superficial chymotrypsin-like protease activity [kallikrein-7 (KLK-7)] and filaggrin-derived natural moisturizing factors (NMF)...

As lifetime exposure to ultraviolet (UV) radiation has risen, the deleterious effects have also become more apparent. Numerous sunscreen and skincare products have therefore been developed to help reduce the occurrence of sunburn, photoageing, and skin carcinogenesis. This has stimulated research into identifying new natural sources of effective skin protecting compounds. Alkaline single-cell gel electrophoresis (comet assay) was employed to assess aqueous extracts derived from soil or hydroponically glasshouse-grown roots of Althea officinalis (Marshmallow) and Astragalus membranaceus, compared with commercial, field-grown roots...
