Facial expression under stiff stratum corneum leads to strain concentrations, followed by residual wrinkle formation
ConclusionBecause exposure to dry or humid conditions in the short‐term could affect only stratum corneum mechanics, the present results indicated that stratum corneum could be considered to be responsible for localized strain during facial expressions. This strain is followed by residual wrinkle formation. Accumulation of residual wrinkles will produce permanent wrinkles in the long‐term. Improving the mechanics of stratum corneum might be an effective approach in wrinkle formation prevention.This article is protected by copyright. All rights reserved.

Inhibition of TRPV1 prevented skin irritancy induced by phenoxyethanol. A preliminary in vitro and in vivo study
ConclusionsDifferent to capsaicin, phenoxyethanol did not down regulate the expression of TRPV1 in HaCaT cells, suggesting that different regulatory mechanisms may exist for capsaicin and phenoxyethanol. Our experiments demonstrated that phenoxyethanol induces skin misperception and uncomfortable skin sensations like itching and burning comparable to capsaicin via activating TRPV1.The stimulation was inhibited by blocking TRPV1 with ID1609. The present data strengthened hitherto studies that TRPV1 plays a critical role in sensitive skin.This article is protected by copyright. All rights reserved. (Source: International Jou...

A fundamental investigation into aspects of the physiology and biochemistry of the stratum corneum in subjects with sensitive skin
ConclusionsDespite the physiological similarities between the two groups of sensitive skin subjects, differences in their biochemistry were clearly evident. Lower levels of PCA, BH and TG activities together with a greater number of smaller and immature corneocytes indicate inferior SC maturation in the capsaicin‐sensitive subjects. The reduced maturation of corneocytes and thinner SC likely contributes to a greater penetration of capsaicin and the associated increased skin sensitivity.This article is protected by copyright.

Understanding effects of topical ingredients on electrical measurement of skin hydration
ConclusionsBoth the Corneometer® and Skicon® were influenced to different extents by chemicals other than water and therefore cannot be seen purely as measures of skin ‘hydration’. While there is strong evidence that the devices do correlate with expert assessment of skin dryness the level of water in the skin is only part of the story when it comes to understanding the benefits of topical moisturizing products applied to the skin. An alternative approach would be to consider skin ‘moisturization’ as a property which is influenced by water, salts and other materials such as humectants and emollients, which is mor...

Variation in the activities of late stage filaggrin processing enzymes, calpain‐1 and bleomycin hydrolase, together with pyrrolidone carboxylic acid levels, corneocyte phenotypes and plasmin activities in non‐sun exposed and sun‐exposed facial stratum corneum of different ethnicities
ConclusionVariation in PCA levels has been found for different ethnic groups in this study (AA > BA > C subjects). The values in the AA subjects are surprising as one might expect that the lack of pigmentation, and thereby increased photodamage, might lead to lower levels. Increased BH, but not C1 activity, was observed in the AA subjects indicating that BH is associated with PCA production to a greater extent. Surprisingly, corneocyte maturation is still impaired with elevated PCA levels in AA subjects. The higher levels of plasmin and BH activities on the cheeks, especially for AA and C subjects, suggest that they ...

Plant‐based active photoprotectants for sunscreens
Abstract Excessive exposure to the sun's radiation is the major exogenous mediator of skin damage, which accelerates skin ageing and increases the risk of developing skin cancer. Compounds with photoprotectant activity are extremely useful for decreasing the effect of ultraviolet (UV) radiation on the skin; however, numerous sun filters, especially organic sunscreens, are allergenic. Therefore, the development of formulations containing plant extracts, which may be potentially safer, is extensively being explored. Plant‐based cosmetics are commonly used to avoid skin ageing because they contain antioxidant agents that mi...

Antimicrobial activity of Butyl acetate, Ethyl acetate and Isopropyl alcohol on undesirable microorganisms in cosmetic products
ConclusionProducts containing more than 5% ethyl or butyl acetate or more than 10% isopropyl alcohol are hostile towards microbial growth. These products can therefore be considered as microbiologically low‐risk during both production and use, and so do not require microbiological testing (challenge‐test and end product testing). Moreover, the nine tested mixtures of these three solvents — which are characteristic of nail varnish compositions — all have a high cidal activity on the tested strains within a short time. The risk of cross‐contamination can therefore be considered as controlled when the nail varnishes...

Increased level of tumor necrosis factor‐alpha (TNF‐α) on the skin of Japanese obese males: measured by quantitative skin blotting
ConclusionWe found that high levels of TNF‐α were detected on the skin of Japanese obese males, which implied the higher TNF‐α in the skin. The elevation of skin TNF‐α may be one factor related to skin fragility that is often found in obese individuals.This article is protected by copyright. All rights reserved.

CRM1 and chromosomal passenger complex component survivin are essential to normal mitosis progress and to preserve keratinocytes from mitotic abnormalities
ConclusionBasal keratinocytes may divide frequently during skin lifespan, and signs of deterioration could appear such as loss of protein factors required for correct mitosis. Our findings suggest that mitotic abnormalities can be prevented by the modulation of CRM1 and survivin. We demonstrated the ability of compound “IV08.009” to efficiently protect cultured keratinocytes from mitotic abnormalities.This article is protected by copyright. All rights reserved.

Fatty acid profile of new promising unconventional plant oils for cosmetic use
ConclusionFA composition of cosmetic oils in combination with data concerning their oxidative quality, is very important for determining their safe and effective use. It is very important to standardize and test the FA content in commercially available oils of cosmetic use. Résumé ObjectifLes huiles ont été utilisées en application cosmétique depuis l'antiquité. Avec l'intérêt croissant dans la formulation cosmétique strictement “naturelle”, il y a eu aussi un intérêt accru pour l'utilisation d'huiles obtenues à partir de noix, des herbes, de fruits et de graines de légumes. En raison d'un manque de bons...
