Ultraviolet B (UVB) irradiation plays a key role in skin damage, which induces oxidative and inflammatory damages, thereby causing photoaging or photocarcinogenesis. Lycium barbarum polysaccharide (LBP), the most biologically active fraction of wolfberry, possesses significant antioxidative and anti-inflammatory effects on multiple tissues. In the present study, the photoprotective effects and potential underlying molecular mechanisms of LBP against UVB-induced photo-damage were investigated in immortalized human keratinocytes (HaCaT cells)...

It is hypothesized that certain chemicals in personal care products may alter the risk of adverse health outcomes. The primary aim of this study was to use a data-centered approach to classify complex patterns of exposure to personal care products and to understand how these patterns vary according to use of exogenous hormone exposures, oral contraceptives (OCs) and post-menopausal hormone therapy (HT). The NIEHS Sister Study is a prospective cohort study of 50,884 US women. Limiting the sample to non-Hispanic blacks and whites (N=47,019), latent class analysis (LCA) was used to identify groups of individuals with similar patterns of personal care product use based on responses to 48 survey questions...

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...

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...

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...

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...
