A novel UV-fluorescence approach to assess the long wear efficacy of foundations.

Background: The long wear properties of foundations are regarded as a must-have in terms of claims. Here, we propose an instrumental approach based on UV-fluorescence imaging as an alternative to clinical grading methods.

Methods: A method was developed, with UV-fluorescence images captured with the Visia CR as a first step, followed by images analysis using Image-Pro plus.

Clinical evidences of benefits from an advanced skin care routine in comparison with a simple routine.

Background: The use of a skin care routine is commonly promoted by the cosmetic industry, yet there is a lack of clinical evidence to support this practice over the use of a single skin care product.

Aims: In the present study, we aimed at showing the clinical benefits of using a comprehensive skin care routine vs a simple one.

Methods: Skin micro-/macro-topographic, skin color, and superficial/deep hydration were collected at baseline and after 4 weeks of use, on forty-nine women randomly allocated to two groups.

DermaTOP Blue and Antera 3D as methods to assess cosmetic solutions targeting eyelid sagging.

Background: As the eye contour ages, the skin on the lid becomes lax often causing a voluminous protrusion where the superior palpebral sulcus begins to sag onto the upper eyelid. This sagging feature may present a novel anti-ageing target for cosmetic products when treating the eye area. A quantitative method to evaluate the volume of this sagging feature has not been previously established.

Evidence of enhanced conjugation in ortho-arylene ethynylenes with transition metal coordination.

The effective conjugation of ortho and ortho-alt-para-arylene ethynylenes, with appropriately positioned pyridine and pyrazine heterocycles, increases upon binding to Ag(I) and Pd(II) cations. Significant bathochromic shifts in the electronic spectra, witnessed upon introduction of these metal bridges, are consistent with enhanced electron delocalization in the unsaturated backbone. Control studies suggest that this electronic behavior is attributable exclusively (in the case of Ag(I)) or partially (in the case of Pd(II)) to conformational restrictions of the conjugated backbones.
