| Résumé : |
In addition to wrinkles and sagging skin, age spots are also considered hallmarks of ageing. UV-induced damage and its accumulation with time underly the formation and the appearance of age spots. Indeed, a time-dependent progression of the histological morphology of age spot lesions has recently been described using reflectance confocal microscopy. The involvement of UV as a causal agent in the formation of age spots also appears to draw in pro-inflammatory pathways.'''° As per its clinically demonstrated reduction of UV-induced erythema, the age spot/luminescence active (activoil spotless) most likely down regulates the inflammatory cascade triggered upon sun exposure that can ultimately participate in age spot formation.
The use of a formulation containing 2% Activoil Spotless succeeded to significantly reduce the appearance of age spots in placebo-controlled, split-face trials and the effect was observed after 30 days. Results obtained with the Mexameter (melanin¬specific) were somewhat comparable to those obtained by measuring the ITA° (not specific to any chromophore) with the spectrophotometer. This observation could reveal that the reduction in age spot appearance is mostly due to a reduction in melanin pigment (decrease in synthesis or an increase in degradation). However, even though the contribution of other pigments such as lipofuscin to age spots formation remains to be demonstrated, it cannot be excluded that Activoil Spotless may simultaneously act on pigments other than melanin when reducing age spot appearance.
The clinical action of Activoil Spotless is not limited to age spots but also extends to skin luminescence. A significant improvement in the spectrophotometry L* parameter was observed already after 30 days and this action progressed up to Day 60. This increase in the parameter L" also reveals a unique anti-ageing action for Activoil Spotless that can translate into a 'youth gain' of up to 10 and 20 years in terms of skin luminescence.
Since multiple pathways appear to join their actions in forming age spots, using an ingredient such as Activoil Spotless itself made of a combination of stabilised lipophilic active components emerges as being an ideal cosmeceutical tool in reducing and preventing the appearance of age spots and improving skin luminescence. |
