FOR, Edouard Mauvais-Jarvis, Director of the scientific communication of Dior

"The night is a time-out. Both use it to benefit the skin care! Especially since she is finally free from aggressions and that once her head on the pillow, no longer dread to shine. You can use it to apply more nourishing textures. This is a privileged moment for cell repair. The skin, "out of gravity", can recreate material in the right places. The ideal cocktail? Antioxidants (to block the chain of radical reactions produced during the day) and repairing active ingredients. All the skins, in my opinion, need this nocturnal meal, whatever the season. But the need for repair is all the more important as the skin has undergone strong aggressions during the day (UV excess in summer, cold in winter). This is valid whatever the age, because the aggressions endured are the same for everyone. However, the older you become, the less the skin repairs itself: the night cream becomes even more essential. "

AGAINST, Hervé Hérau, creator of the eponymous brand

"Night is the privileged moment of cell renewal and toxin elimination. A real cleansing then takes place in the heart of our skin, which must not be opposed. When you sleep, the microcirculation intensifies, a sign that the skin is oxygenated. If you apply a night cream, you simply "smother" it! Worse, you accelerate its aging. Especially since its texture is often very rich. You may wake up with swollen areas. Same with an eye contour care. The only product I can possibly imagine is a fruit acid cream, designed to optimize cell renewal. At least it goes in the right direction. But the product used must be cast in a fluid texture, very rich in water. However, nothing replaces a night without night cream, in my opinion. This advice is valid for all skin types, even in winter. I know that dry skin is hard to keep naked. But the epidermis soon gets used to! In three to four days, all the tugging ceased. "
