La Prairie Skin Caviar Luxe Sleep Mask

La Prairie Skin Caviar Luxe Sleep Mask is a fragrance in a 50 ml bottle. A fragrance opens brightest in the first few minutes; what is left an hour later is the part you actually live with. A spray on clothing or in the hair lasts longer than one on skin, though it can shift the balance of the scent and mark delicate fabrics. Discounted listings come and go, and rarely at the same shop twice. Keep the bottle out of sunlight and away from bathroom humidity — a cool, dark drawer preserves it for years, a windowsill turns it in months. The cheapest listing is not automatically the best deal: delivery and any code applied at checkout decide that.
