Free radical scavenging properties of mannitol and its role as a constituent of hyaluronic acid fillers: a literature review
Abstract Mannitol has both hydrating and antioxidant properties that make it an ideal excipient for use with hyaluronic acid (HA) fillers. This review examines the role of reactive oxygen species in the ageing process and their effects on both endogenous HA and HA products developed for aesthetic use. Evidence is presented to show that the free radical scavenging properties of mannitol provide it with a two‐fold mechanism of action when combined with HA fillers: reducing the inflammation and swelling associated with the injection procedure itself, and preventing the degradation of the injected HA by free radicals. Mannit...

A robust sebum, oil, and particulate pollution model for assessing cleansing efficacy of human skin
Abstract With increasing concerns over the rise of atmospheric particulate pollution globally and its impact on systemic health and skin ageing, we have developed a pollution model to mimic particulate matter trapped in sebum and oils creating a robust (difficult to remove) surrogate for dirty, polluted skin. ObjectiveTo evaluate the cleansing efficacy/protective effect of a sonic brush vs. manual cleansing against particulate pollution (trapped in grease/oil typical of human sebum). MethodsThe pollution model (Sebollution; sebum pollution model; SPM) consists of atmospheric particulate matter/pollution combined with greas...

Polygonum multiflorum Radix extract protects human foreskin melanocytes from oxidative stress in vitro and potentiates hair follicle pigmentation ex vivo
ConclusionPolygonum multiflorum Radix extract protects in vitro primary human foreskin melanocytes from the deleterious effects of H2O2‐exposure and improves pigmentation within ex vivo human hair follicles, demonstrating the utility of Polygonum multiflorum Radix extract as a potential active ingredient for the protection of melanocytes against premature death. This data provides in vitro mechanistic evidence consistent with existing in vivo studies for the use of Polygonum multiflorum Radix extract as a strategy for the prevention of oxidative‐stress induced hair greying, in line with traditional Polygonum multifloru...

Climbazole Boosts Activity of Retinoids in Skin
ConclusionClimbazole boosted retinoid activity both in the SE model, after a combined topic treatment with either retinol or retinyl propionate, and in vivo, in combination with a low level of retinol. Based upon the evidence presented here, we suggest that the topical skin application of climbazole in combination with retinoids, could deliver skin aging benefits more than a less robust retinoid alone.This article is protected by copyright.

Elastin structure and its involvement in skin photoageing
Abstract Skin aging is a complex process that may be caused by factors that are intrinsic and extrinsic to the body. Ultraviolet (UV) radiation represents one of the main sources of skin damage over the years and characterizes a process known as photoaging. Among the changes that affect cutaneous tissue with age, the loss of elastic properties caused by changes in elastin production, increased degradation and/or processing produces a substantial impact on tissue esthetics and health. The occurrence of solar elastosis is one of the main markers of cutaneous photoaging and is characterized by disorganized and non‐functiona...

Dynamics of glycerine and water transport across human skin from binary mixtures
ConclusionThese studies confirm that glycerine enters HSC in substantial quantities and has a long residence time therein. The coupling between bulk water and glycerine transport projected from binary solution data suggests the net effect of glycerine is to slow water loss from the skin. The data support the concept of glycerine as a humectant with an excellent balance of skin penetration and retention characteristics; however, they do not rule out the possibility of an additional biological effect on skin barrier homoeostasis.

Effects of hair sprays on colour perception: a hyperspectral imaging approach to shine and chroma on heads
ConclusionsHair sprays are generally employed for hair style hold and weather resistance and considered without effect on hair colour. Our approach shows that spray‐deposited films can affect colour perception by altering the microstructure of the hair surface. Thin films deposited on the hair fibre surface can partially fill gaps between cuticles, which reduces the cuticle natural angle. This partial erasure results in a angle shift of the shine regions towards the angle of internal reflection, thus decreasing the perceived hair colour regions as experienced by a group of consumers.
