Did you know that environmental exposure causes up to 80% of your skin's ageing? Internal and external aggressors, such as pollution, sun exposure, stress and diet are all silently ageing your skin each day. Collectively, these factors are known as the 'Exposome'. Developed after 9 years of research, Vichy introduces Slow Âge; our most powerful probiotic skincare range with SPF, specifically designed to counteract the effects of the Exposome and clinically proven to slow down the appearance of ageing signs. Slow down. Age well.
