Le Grand Sérum is composed of an innovative combination of 27 anti-wrinkle, antioxidant, firming and regenerating ingredients, protecting the skin throughout the entire day. Highly effective, TélomerActiv improves telomere stability and longevity to help prevent the irreversible accumulation of cell aging markers. This revolutionary anti-senescence active ingredient slows the cell aging process and increases collagen production. Its regenerating action stimulates and regenerates support tissues to reactivate cellular metabolism. Its formula also contains anti-wrinkle active ingredients to fight the signs of aging. It immediately promotes muscle relaxation and neutralises muscle contractions responsible for facial expression wrinkles. On the long term, these active ingredients will activate collagen synthesis, thus providing anti-wrinkle actions by reducing wrinkle depth. Its firming active ingredients have been selected for their activity on cell renewal, which stimulates fibroblast growth and collagen synthesis. Le Grand Sérum also has antioxidant action, thanks to active ingredients that strengthen cell defence mechanisms, capture free radicals, and protect the skin from aging. A true complexion revealer, it bathes the skin in golden light and restores incomparable radiance.
