Get the most benefit out of the night for your skin: the active renewal of cells takes place from 11:00 p.m. to 4:00 a.m. — but that’s only if you’re asleep! During the nighttime, the hormone cortisol is produced, which promotes the destruction of skin cells. But if you’re asleep, your body produces another substance — growth hormone. Recovery cream intensifies skin regeneration at the cellular level, restoring its energy and vitality. It works while you rest.
