Résumé : |
The quest for means to get a beautiful skin is endless. However, defining what is beautiful partially depends on the geographical and ethnic origins of the persons. For instance, having a white skin is an extremely important element of the women's beauty in Asian culture. The desire for white skin originally cornes from traditional Asian values and beliefs. This desire has also been reinforced by Western influences (for instance Caucasian models are often used in adverts for European or American cosmetic brands sold in Asian countries). That is the reason why whitening/lightening products are among the best-selling products in the Asian cosmetic industry and are also becoming very important in Middle East, Africa and South America. In these areas, for many people, hyperpigmentation and skin pigmentary spots are not only considered as aesthetic problems, but they are also synonymous of decreased self-esteem, premature skin ageing and may facilitate the occurrence of skin damages, exacerbated by sun exposure. Conversely, Caucasians are looking to tan their skin since many consider tanning as a marker of a healthy lifestyle. But recent global consumer surveys on the primary cosmetic concerns of women have identified uneven skin tone and age spots as major concerns relative to signs of ageing. Trying to maintain or to regain a uniform skin tone, clear of age spots, is therefore a major and shared objective to consumers worldwide. |
